Answers

Answer 1

To solve the circuit and find the currents and voltages, we can use Ohm's Law and Kirchhoff's Laws.

(a) The currents: IR1, IR2, IR4, and IR5. Using Ohm's Law (V = IR), we can calculate the currents:

IR1 = VR1 / R1

IR1 = VR1 / 8kΩ

IR2 = VR2 / R2

IR2 = VR2 / 2kΩ

IR4 = VR4 / R4

IR4 = VR4 / 4kΩ

IR5 = VR5 / R5

IR5 = VR5 / 5kΩ (b) The voltages: VR1, VR4, VR6, and VR7mUsing Kirchhoff's Voltage Law (KVL), we can determine the voltages: For VR1, we need to consider the voltage drop across R2 and R3: VR1 = VR2 + VR3. For VR4, we need to consider the voltage drop across R5: VR4 = VR5. For VR6, it is directly connected to the voltage source, so VR6 is equal to the source voltage. VR7 is the voltage drop across R7. (c) The power absorbed by resistor R7. The power absorbed by a resistor can be calculated using the formula P = IV, where P is power, I is current, and V is voltage. P7 = IR7 * VR7. To find the exact values of the currents and voltages, we need the specific values of the voltage source or additional information about the circuit configuration.

Question 6 5 pts At a distance of 3.66 mm from a sheet with uniform surface charge density o, the electric field points toward the sheet with a magnitude of 1220 N/C. What is the value of o? (1 nC = 1

Answers

The value of the uniform surface charge density o is 3.334 × 10^(-7) C/m².

The electric field near a charged sheet can be calculated using the formula:

E = σ / (2ε₀)

where E is the electric field, σ is the surface charge density, and ε₀ is the permittivity of free space.

Given that the electric field magnitude E is 1220 N/C and the distance from the sheet is 3.66 mm (or 0.00366 m), we can rearrange the formula to solve for σ:

σ = 2ε₀E

Substituting the values, we have:

σ = 2 * (8.854 × 10^(-12) C²/Nm²) * 1220 N/C

σ = 2 * 8.854 × 10^(-12) * 1220 C/m²

σ ≈ 3.334 × 10^(-7) C/m²

Therefore, the value of the uniform surface charge density o is approximately 3.334 × 10^(-7) C/m².

what is ex(p), the value of the x-component of the electric field produced by by the line of charge at point p which is located at (x,y) = (a,0), where a = 9.7 cm?

Answers

The value of the x-component of the electric field produced by the line of charge at point p  4.639 × 10^4 N/C

Ex(p) = keλ / a

The electric field generated by the line of charge at any point is given by

E = keλ / r,

where ke is Coulomb’s constant, λ is the charge per unit length, and r is the distance from the line to the point where the electric field is determined.

A point P is located on the x-axis a distance of a = 9.7 cm from the line of charge. The charge on an infinitesimal element of length ds is dQ = λ ds, so the electric field dE produced by this charge at point P is

dE = ke dQ / r'.

The total electric field at point P produced by the entire line is obtained by integrating the expression for dE over the entire line. We find

Ex(p) = ke λ / a

Consequently, the value of the x-component of the electric field at point P isE

x(p) = ke λ / a = (9 × 10⁹ N·m²/C²)(5 µC/m) / (9.7 × 10⁻² m) = 4.639 × 10⁴ N/C

Thus, the magnitude of the electric field at point P is 4.639 × 10⁴ N/C, directed to the left.

The value of the x-component of the electric field produced by the line of charge at point p which is located at (x,y) = (a,0), where a = 9.7 cm is Ex(p) = keλ / a = (9 × 10⁹ N·m²/C²)(5 µC/m) / (9.7 × 10⁻² m) = 4.639 × 10^4 N/C

what is the frequency of radiation whose wavelength is 0.95 nm ?

Answers

The frequency of radiation with a wavelength of 0.95 nm is 3.16 x 10^17 Hz.

The frequency of radiation whose wavelength is 0.95 nm can be found using the formula: frequency = speed of light / wavelength.

The speed of light is a constant and is approximately 3.00 x 10^8 m/s.So, first we need to convert the given wavelength to meters.

A 0.535-kg mass suspended from a spring undergoes simple harmonic oscillations with a period of 1.55 s How much mass, in kilograms, must be added to the object to change the period to 1.75 s?

Answers

0.207 kg or approximately 0.21 kg mass must be added to the object to change the period to 1.75 s.

Given, a mass of 0.535 kg suspended from a spring undergoes simple harmonic oscillations with a period of 1.55 s.

From the given information, we can use the formula of time period of simple harmonic motion as:

T = 2π √(m/k) where T is the time period, m is the mass, and k is the spring constant.

Since we want to find how much mass must be added to change the period from 1.55 s to 1.75 s, we can set up an equation:T1 = 1.55 s, T2 = 1.75 sT1 = 2π √(m/k)T2 = 2π √((m+M)/k)where M is the mass that needs to be added.

From the given information,T1 = 2π √(0.535/k)T2 = 2π √((0.535+M)/k)

Dividing the second equation by the first equation,

T2/T1 = √((0.535+M)/0.535)

Squaring both sides,T2²/T1² = (0.535+M)/0.535

Now we can solve for M,

M = (T2²/T1² - 1) × 0.535M = (1.75²/1.55² - 1) × 0.535M = 0.207 kg

Thus, 0.207 kg or approximately 0.21 kg mass must be added to the object to change the period to 1.75 s. This is because the time period of an oscillating mass is directly proportional to the square root of its mass. By adding mass to the object, we increase its mass and hence increase its time period.

Answers

The weight of the object on the bathroom scale is calculated by multiplying the mass of the object by the acceleration due to gravity. The acceleration due to gravity is a function of both the mass of the planet and the distance from the object to the center of the planet.

The object of mass 6.641 kg is placed on a bathroom scale on the equator of a planet. The acceleration of gravity on the planet is given to be 2.482 m/s². If the planet did not rotate, the acceleration of gravity at the equator would be the same as the acceleration at any other point on the planet.

However, since the planet is rotating, it bulges out at the equator, causing the distance from the object to the center of the planet to increase and resulting in a decrease in the acceleration due to gravity.

This effect is known as the centrifugal force. The formula for calculating the weight of the object on the bathroom scale is:Weight = mass × acceleration due to gravityOn the equator of the rotating planet, the weight of the object is less than it would be on a non-rotating planet.

This is because the centrifugal force acts in the opposite direction to the force of gravity, effectively reducing the force that the object experiences. Therefore, the weight of the object on the bathroom scale is less than it would be on a non-rotating planet with the same mass and radius.

determine the average emissivity of the filament at (a) 1500 k and (b) 2500 k. also, determine the absorptivity and reflectivity of the filament at both temperatures.

Answers

At 1500 K, the average emissivity of the tungsten filament is 0.325, the absorptivity is 0.325, and the reflectivity is 0.675. At 2500 K, the average emissivity of the tungsten filament is 0.325, the absorptivity is 0.325, and the reflectivity is 0.675.

At 1500 K and 2500 K, we can calculate the tungsten filament's average emissivity, absorptivity, and reflectivity.

Emissivity is 0.5 for photons with wavelengths < 1 μm. Emissivity is 0.15 for radiation > 1 μm.

(a) 1500 K

We must compute average emissivity (_avg), absorptivity (α), and reflectivity () at this temperature.

The blackbody's spectral range at 1500 K determines the average emissivity. Emissivity is 0.5 for < 1 μm and 0.15 for > 1 μm.

Stefan-Boltzmann law calculates average emissivity:

(A1 + A2)/(A1 + A2) = _avg.

Where: 0.5 (emissivity for < 1 μm) 0.15 (emissivity for > 1 μm).

A1 and A2 are spectral range regions.

Calculate the average emissivity assuming equal regions for both spectral bands (A1 = A2 = 0.5):

ε_avg = (0.5 * 0.5 + 0.15 * 0.5) / (0.5 + 0.5) = 0.325

For opaque materials, absorptivity (α) equals emissivity. Thus, α = 0.325_avg.

Reflectivity is the counterpart of absorptivity: - α = 1 - 0.325 = 0.675.

Thus, at 1500 K, the average tungsten filament emissivity, absorptivity, and reflectivity are 0.325, 0.325, and 0.675, respectively.

2500 K

We can determine 2500 K average emissivity, absorptivity, and reflectivity using the same method.

(0.5 * 0.5 + 0.15 * 0.5) / (0.5 + 0.5) = 0.325.

The average tungsten filament emissivity at 2500 K is 0.325.

Since absorptivity equals emissivity, α = _avg = 0.325.

Reflectivity is the counterpart of absorptivity: - α = 1 - 0.325 = 0.675.

Thus, at 2500 K, the average tungsten filament emissivity, absorptivity, and reflectivity are 0.325, 0.325, and 0.675, respectively.

a) The change in entropy (ΔS) for the isothermal expansion of one mole of an ideal gas, we can use the equation:

ΔS = nR ln(Vf/Vi)

Where:

ΔS is the change in entropy,

n is the number of moles of gas (1 mole in this case),

R is the ideal gas constant (8.314 J/(mol·K)),

Vf is the final volume,

Vi is the initial volume.

Since the volume is expanded to twice its initial value, we have Vf = 2Vi.

Plugging these values into the equation, we get:

ΔS = (1 mole)(8.314 J/(mol·K)) ln(2Vi/Vi)

What is the acceleration on a body that approached the earth and comes within 6 earth radii of the earth's surface? Show your work.

Answers

The acceleration on a body that approaches the Earth and comes within 6 Earth radii of the Earth's surface is approximately 9.82 m/s².

The law of universal gravitation states that the force of gravity between two objects is given by:

F = (G * m₁ * m₂) / r²

Where:

F is the force of gravity

G is the gravitational constant (approximately 6.67430 × 10^(-11) N·m²/kg²)

m₁ and m₂ are the masses of the two objects

r is the distance between the centers of the two objects

To calculate the acceleration at a distance of 6 Earth radii from the Earth's surface, we need to determine the gravitational force acting on the body and then divide it by the mass of the body.

The distance between the body and the Earth's surface is 6 Earth radii. Let's denote it as r.

r = 6 * Earth radius

The acceleration (a) can be calculated as:

a = F / m

Where:

F is the gravitational force between the body and the Earth

m is the mass of the body

Since the mass of the body cancels out, we can calculate the acceleration using:

a = (G * M) / r²

Where:

M is the mass of the Earth

Now, we can substitute the values into the equation:

a = (G * M) / (6 * Earth radius)²

a ≈ (6.67430 × 10^(-11) N·m²/kg² * M) / (6 * Earth radius)²

The value of M, the mass of the Earth, is approximately 5.972 × 10^24 kg, and the Earth radius is approximately 6.371 × 10^6 m.

Substituting these values:

a ≈ (6.67430 × 10^(-11) N·m²/kg² * 5.972 × 10^24 kg) / (6 * 6.371 × 10^6 m)²

The final momentum of the two bodies in a completely inelastic one-dimensional collision can be determined by using the principle of conservation of momentum.

When two bodies collide in a completely inelastic one-dimensional collision, they stick together and move with a common velocity after the collision. In such a collision, the principle of conservation of momentum is applicable. According to this principle, the total momentum of the system before the collision is equal to the total momentum of the system after the collision. Therefore, we can write:Initial momentum of body 1 + initial momentum of body 2 = final momentum of the combined system .Therefore, P1i + P2i = Pfwhere P1i and P2i are the initial momenta of the two bodies and Pf is their final momentum after collision.

What current flows through a 2.56-cm-diameter rod of pure silicon that is 18.0 cm long, when 1.00 ✕ 103 V is applied to it? (Such a rod may be used to make nuclear particle detectors, for example.)

_________________A fill in the blank

Answers

The current flowing through the 2.56-cm-diameter rod of pure silicon, which is 18.0 cm long, when 1.00 ✕ 103 V is applied to it, is approximately 2.17 A.

To determine the current flowing through the rod, we can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the rod is made of pure silicon, so we need to calculate its resistance.

The resistance of a cylindrical conductor can be calculated using the formula R = (ρ * L) / A, where ρ is the resistivity of the material, L is the length of the rod, and A is the cross-sectional area. The resistivity of pure silicon is approximately 640 Ω·cm.

First, let's calculate the cross-sectional area (A) of the rod. The diameter of the rod is 2.56 cm, so the radius (r) is half of that, which is 1.28 cm or 0.0128 m. Using the formula for the area of a circle (A = π * r²), we find that the cross-sectional area is approximately 0.00516 m^2.

Next, we can substitute the values into the formula for resistance: R = (640 Ω·cm * 0.18 m) / 0.00516 m². After performing the calculations, we find that the resistance of the rod is approximately 22,222 Ω.

Finally, we can use Ohm's Law to calculate the current: I = V / R. Substituting the given voltage of 1.00 ✕ 103 V and the resistance of 22,222 Ω, we find that the current flowing through the rod is approximately 2.17 A.

Answers

Part A: The magnitude of the net displacement of the ball is 40 yards.

Part B: The angle between the direction of the net displacement of the ball and the 50-yard line is 0 degrees.

Part A: To find the magnitude of the net displacement of the ball, we can use the Pythagorean theorem since the displacement forms a right triangle.

The horizontal displacement is the distance from the center of the field to the sideline, which is 40 yards.

The vertical displacement is zero since the ball is punted directly from the center of the field to the sideline.

Using the Pythagorean theorem, the magnitude of the net displacement is:

Net displacement = [tex]\sqrt{ (horizontal displacement^2 + vertical displacement^2)}[/tex]

= [tex]\sqrt{(40^2 + 0^2)}[/tex]

= [tex]\sqrt{(1600)}[/tex]

= 40 yards

Therefore, the magnitude of the net displacement of the ball is 40 yards.

Part B: The angle between the direction of the net displacement of the ball and the 50-yard line can be found using trigonometry.

The net displacement forms a right triangle with the horizontal and vertical displacements. The angle we are interested in is the angle opposite the horizontal displacement (40 yards).

Using trigonometry, we can find this angle:

tan(angle) = vertical displacement / horizontal displacement

tan(angle) = 0 / 40

tan(angle) = 0

Since the vertical displacement is zero, the angle is also zero degrees.

Therefore, the angle between the direction of the net displacement of the ball and the 50-yard line is 0 degrees.

Answers

A) I_t = I_i, C) 0.33 m, A) 0.53 times 10^-2 s

Which expression is correct for the transmitted intensity of an unpolarized beam of light passing through a polarizer? What is the wavelength associated with a cordless phone operating at 900 MHz? How much time does a light signal take to go from one planet to another that are 1.6 times 10^6 m apart?

For the first question:

The correct expression for the transmitted intensity of an unpolarized beam of light passing through a polarizer is:

A) I_t = I_i

When an unpolarized light beam passes through a polarizer, the transmitted intensity is equal to the incident intensity. This means that the intensity of the light remains unchanged after passing through the polarizer.

For the second question:

The associated wavelength of a cell phone signal operating at 900 MHz can be calculated using the formula: wavelength = speed of light / frequency.

The speed of light is approximately 3.0 x 10^8 m/s.

Calculating the wavelength:

wavelength = (3.0 x 10^8 m/s) / (900 x 10^6 Hz)

wavelength = 3.33 x 10^-1 m

Therefore, the correct answer is:

C) 0.33 m

The wavelength of the cell phone signal is 0.33 meters.

For the third question:

To calculate the time it takes for a light signal to travel from one planet to another, we need to divide the distance between the two planets by the speed of light.

Calculating the time:

time = distance / speed of light

time = (1.6 x 10^6 m) / (3.0 x 10^8 m/s)

time = 5.33 x 10^-3 s

Therefore, the correct answer is:

A) 0.53 times 10^-2 s

The time for the light signal to travel from one planet to the other is 0.53 times 10^-2 seconds.

a thin film of mgf2 (n = 1.38) coats a piece of glass. constructive interference is observed for the reflection of light with wavelengths of 480 nm and 720 nm . What is the thinnest film for which this can occur?

Answers

the thinnest film for which constructive interference is observed for the reflection of light with wavelengths of 480 nm and 720 nm that is coated with a thin film of MgF2 (n = 1.38) on a piece of glass is approximately 174.27 nm.

let the thickness of the film be x. Then, we have:

For λ = 480 nm:2(1.38)x = m(480 nm)For λ = 720 nm:2(1.38)x = m(720 nm)

We need to find the smallest value of x that satisfies both equations.

We can do this by dividing both equations by the other equation to get:

m(480 nm)/m(720 nm) = 2(1.38)x/2(1.38)x

Simplifying:

480/720 = 2/3

Multiplying both sides by 720:480(720)/720 = 2(720)/3

Simplifying:320 = 480/3

Multiplying both sides by 3:960 = 480

The equation is satisfied when m = 1.

Therefore:2(1.38)x = 1(480 nm)2(1.38)x = 480 nmSimplifying:x = (480 nm)/(2(1.38))x ≈ 174.27 nm

Therefore, the thinnest film for which constructive interference is observed for the reflection of light with wavelengths of 480 nm and 720 nm that is coated with a thin film of MgF2 (n = 1.38) on a piece of glass is approximately 174.27 nm.

why is the entropy for the dissociation of acetic acid negatie

Answers

The entropy for the dissociation of acetic acid is negative because there is an increase in order in the system. These ions are then surrounded by water molecules, which increases the order of the system. Because of this, the entropy change for the dissociation of acetic acid is negative.

Entropy is a measure of the disorder or randomness of a system. When a substance dissociates, its particles move apart and become more disordered. The entropy of the system is expected to increase as a result of this.However, in the case of acetic acid, the opposite is observed. When acetic acid dissociates, it breaks down into acetate ions and hydrogen ions. This phenomenon is also seen in other weak acids, and is known as the "ion pairing effect." When weak acids dissociate, the resulting ions tend to form pairs with each other, which reduces their disorder. This leads to a decrease in entropy for the dissociation of the acid.

Entropy is a thermodynamic quantity that measures the degree of disorder or randomness of a system. The entropy change for a process is determined by the difference between the entropy of the final state and the entropy of the initial state.In the case of the dissociation of acetic acid, the initial state consists of a single molecule of acetic acid, while the final state consists of the products of the dissociation reaction: acetate ions and hydrogen ions in aqueous solution. The entropy of the initial state is relatively low, because the molecules of acetic acid are relatively ordered. However, the entropy of the final state is also relatively low, because the products of the dissociation reaction are surrounded by water molecules, which reduces their disorder. This reduction in disorder leads to a negative entropy change for the dissociation of acetic acid.The ion pairing effect is responsible for the reduction in disorder observed in the dissociation of weak acids like acetic acid. When the acid dissociates, the resulting ions tend to form pairs with each other, which reduces their disorder. This pairing effect is stronger for weak acids than for strong acids, because weak acids dissociate to a lesser extent, which leads to a greater concentration of ions in solution. As a result, the entropy change for the dissociation of weak acids is more negative than for strong acids.

QUESTION 3 A small particle experiences an electrostatic force of 10.0 N to the East when placed in an electric field of 8.77 N/C to the West. What is the charge is the electric charge on the particle

Answers

The electric charge on the particle is -1.14 μC (microcoulombs).

To determine the electric charge on the particle, we need to use the formula for electrostatic force:

F = qE

where F is the magnitude of the electrostatic force, q is the charge on the particle, and E is the magnitude of the electric field.

Given that the particle experiences a force of 10.0 N to the East and the electric field is 8.77 N/C to the West, we can deduce that the direction of the electric force is opposite to the direction of the electric field. This means that the charge on the particle is negative.

Using the formula F = qE, we rearrange the equation to solve for q:

q = F/E

Substituting the given values, we have:

q = 10.0 N / (-8.77 N/C) = -1.14 C

The charge is negative because it is opposite in sign to the electric field. Converting the charge to microcoulombs:

q = -1.14 × 10⁻⁶ C = -1.14 μC

Therefore, the electric charge on the particle is -1.14 μC (microcoulombs).

what would be a car's mpg at average values of the inputs? (upto two decimal points)

Answers

To provide an estimate of a car's MPG (miles per gallon) at average values of the inputs, we need specific information regarding the car's fuel efficiency, driving conditions, and engine specifications.

The MPG value can vary significantly based on factors such as the car's make, model, engine type, transmission, weight, aerodynamics, driving style, and road conditions.

However, as a rough approximation, the average MPG for a typical gasoline-powered car is around 25-30 MPG in mixed driving conditions. For a hybrid vehicle, the average MPG can range from 40-50 MPG. Electric vehicles (EVs) do not use MPG as a metric since they are powered by electricity and typically measured in terms of miles per kilowatt-hour (miles/kWh).

It's important to note that the actual MPG a car achieves can vary from these average values based on various factors. For a more accurate estimate, specific details about the car's make, model, and any additional parameters would be necessary.

Answers

The power series representation of a function and the radius of convergence can be determined using mathematical techniques.

How can the power series representation and radius of convergence of a function be determined?

To find the power series representation and the radius of convergence of a function, we can use methods such as Taylor series expansion and the ratio test.

In the Taylor series expansion, a function is represented as an infinite sum of terms, each of which is a power of the independent variable multiplied by a coefficient. This series provides an approximation of the function in terms of its derivatives evaluated at a specific point. The radius of convergence, denoted by r, is the distance from the center of the series expansion within which the series converges.

The ratio test is another method used to determine the radius of convergence. By taking the limit of the ratio of consecutive terms in the series, we can determine whether the series converges or diverges. The radius of convergence is the distance from the center of the series expansion where the ratio of consecutive terms approaches a specific value less than one.

in δefg, e = 75 cm, m∠g=141° and m∠e=16°. find the length of g, to the nearest centimeter.

Answers

The length of g is 114 cm, to the nearest centimeter.

In a triangle, the sum of the interior angles is 180 degrees. Thus, the measure of the third angle in triangle DEF can be calculated as follows: 180 - 16 - 141 = 23 degrees. Since we know that triangle DEF is similar to triangle GFE (by AA similarity), we can set up a proportion to find the length of GF.

Let x be the length of GF, so we have

x/75 = GF/DE => GF = 75x/DE.

To find GF, we need to determine the length of DE. We can use the sine rule to do so:

DE/sin(141) = 75/sin(23)

=> DE = 75*sin(141)/sin(23).

Now we can substitute the value of DE and solve for x:

GF = 75x/DE = 75x*sin(23)/(75*sin(141))

=> GF = x*sin(23)/sin(141)

Answers

Given that the asteroid takes 924.137 days to orbit the Sun, we need to find its orbital radius in millions of kilometers. We will use Kepler's third law of planetary motion to find the distance.

Kepler's third law of planetary motion is given by:T² ∝ R³Where T is the time period of the orbit and R is the mean distance of the object from the center of mass of the system.So, T² = kR³Where k is a constant of proportionality, which is the same for all the planets and satellites orbiting the same star.

Using the given data,T = 924.137 days The time period of one earth year = 365.2422 days Therefore, the time period of the asteroid in earth years = 924.137/365.2422 = 2.5299 yearsTaking k = 1, we getT² = R³2.5299² = R³6.4203 = R³Therefore, the orbital radius R = ∛6.4203 million km ≈ 1.906 million kmHence, the orbital radius of the asteroid is approximately 1.906 million km.

what is the speed of a 11 g bullet that, when fired into a 12 kg stationary wood block, causes the block to slide 5.2 cm across a wood table? assume that μk = 0.20.

Answers

The speed of an 11 g bullet that, when fired into a 12 kg stationary wood block, causes the block to slide 5.2 cm across a wood table is 574.7 m/s.

According to the principle of conservation of momentum, the momentum of the bullet before collision equals the sum of momentum of bullet and block after the collision. Thus: mv = (m + M)V; Here, m = 11 g = 0.011 kg (mass of bullet), M = 12 kg (mass of block), V = velocity of block and bullet after collision. v = velocity of bullet before collision.

Substituting the given values in the above equation and solving for V: 0.011v = (12 × V) - 0.20 × (12 × 9.81 × 0.052)V

0.011v / 12 - (0.20 × 12 × 9.81 × 0.052) / 12V

v / 1090.1 - 0.1017V

v / 1090.1.

The distance traveled by the block after collision is 5.2 cm or 0.052 m. Thus, V² - u² = 2as

= 2 × 0.20 × 9.81 × 0.052V² - (v / 1090.1)²

= 0.02152V² = (v / 1090.1)² + 0.02152V²

= 0.0000121 + 0.02152V²

= 0.0215321V = √0.0215321V

Answers

A 20.0 kg cannonball is fired from a cannon with a muzzle speed of 100 m/s at an angle of 20.0°. Using conservation of energy, the maximum height reached by the cannonball is approximately 510.2 meters.

A cannon ball weighing 20.0 kg is launched from a cannon with an initial velocity of 100 m/s at an angle of 20.0° above the horizontal.

To determine the maximum height reached by the cannonball using the conservation of energy principle, we consider the conversion of kinetic energy into gravitational potential energy.

Initially, the cannonball has only kinetic energy, given by the equation KE = (1/2)mv², where m is the mass and v is the velocity.

At the highest point of its trajectory, the cannonball has no vertical velocity, meaning it has no kinetic energy but possesses gravitational potential energy, given by the equation PE = mgh, where h is the height and g is the acceleration due to gravity (approximately 9.8 m/s²).

Using the conservation of energy, we equate the initial kinetic energy to the maximum potential energy:

(1/2)mv² = mgh

Canceling the mass and rearranging the equation, we find:

v²/2g = h

Plugging in the given values, we have:

(100²)/(2*9.8) = h

Simplifying the equation, we find:

h ≈ 510.2 m

Therefore, the maximum height reached by the cannonball is approximately 510.2 meters.

Answers

The speed of light in a vacuum is 2.997×10⁸ m/s.

Given that the index of refraction in fresh water is 1.333, the speed of light in fresh water can be calculated by using the formula:

n1 * v1 = n2 * v2,

where n1 and n2 are the indices of refraction of the two media, and v1 and v2 are their respective speeds.

We have:

n1 = index of refraction of vacuum = 1 (since there is no medium, there is no change in speed)

n2 = index of refraction of fresh water = 1.333v1

= speed of light in vacuum = 2.997×10⁸ m/sv2

= speed of light in fresh water

We can substitute the given values and solve for v2 as follows:

1 * (2.997×10⁸ m/s) = 1.333 * vv2 = (1 * 2.997×10⁸ m/s) / 1.333v2 = 2.247 × 10⁸ m/s
