The given figure shows two rectangular tanks full of water.

Tanks have equal depths and equal thickness but different widths.

The pressure of liquid depends on the density and depth below the surface (or opening) and atmospheric pressure.

P = hρg + Atmospheric pressure.

Where

P = pressure

h = depth of point from the surface or opening

ρ = density of liquid

g = gravitational acceleration

And force is given as F = P x A

Where P = pressure and A= cross-sectional area.

Lets assume the depth of the tanks = h.

Width of the tanks = [tex]w_A[/tex] and [tex]w_B[/tex] , where [tex]w_A[/tex] > [tex]w_B[/tex] ,

Their wave speeds will be equal. Therefore, the rank of the wave speeds from largest to smallest is equal, as they are all traveling at the same speed.

To rank the three wave pulses traveling along the same stretched string from largest to smallest wave speeds, we'll consider the factors affecting wave speed: tension and linear density. Here's the explanation:

Recall the wave speed formula:

v = √(T/μ),

where v is the wave speed, T is the tension in the string, and μ is the linear density (mass per unit length) of the string. Since all three wave pulses are on the same string, the linear density (μ) remains constant.

The wave speed (v) depends on the tension (T) in the string. The higher the tension, the faster the wave speed.

To rank the wave pulses from largest to smallest wave speeds, you'll need to know the tension in the string for each pulse. Without specific information about the tensions of the three wave pulses, we can't provide a definite ranking. However, once you know the tensions, you can apply the wave speed formula and rank the pulses accordingly.

Answer:

First, we need to calculate the new volume of the glycerin at 30°C using the thermal expansion coefficients:

ΔV = V₀ * a * ΔT

where:

- V₀ = initial volume of glycerin at 20°C = 1.8 L

- a = thermal expansion coefficient of copper = 1.7 x 10-³ [2] °C-1

- ΔT = temperature increase = 30°C - 20°C = 10°C

ΔV = 1.8 L * 1.7 x 10-³ [2] °C-1 * 10°C = 0.0306 L

The new volume of glycerin at 30°C is:

V = V₀ + ΔV = 1.8 L + 0.0306 L = 1.8306 L

However, the volume of the kettle is only 1.8 L, so some glycerin will spill out. The amount of glycerin that spills out is equal to the excess volume:

ΔV_spill = V - V₀ = 1.8306 L - 1.8 L = 0.0306 L

Therefore, 0.0306 L of glycerin will spill out when the temperature of the copper kettle rises from 20°C to 30°C.

By using equations for thermal expansion, we can determine the amount of glycerin that will spill from the kettle as it is heated from 20°C to 30°C. The difference in thermal expansion coefficients between glycerin and copper (which the kettle is made from) means the glycerin will spill. Approximately 9.54 milliliters of glycerin will spill out.

This question is about thermal expansion, a concept in physics. When objects are heated, they generally expand, and when they are cooled, they contract. The specifics of the expansion can be determined by coefficients of thermal expansion. In this case, for glycerin, it's denoted as 'y' and for copper as 'a'.

The volume change (∆V) will be given by: ∆V = Vo.y.∆T where Vo is the initial volume, y is the coefficient of thermal expansion and ∆T is the change in temperature.

Here, ∆V = 1.8 L * 5.3 x 10^-4 °C^-¹ * (30°C - 20°C) = 0.00954 liters = 9.54 milliliters of glycerin will spill out. Also remember that the copper kettle will also expand, but as 'a' for the copper is less than 'y' for the glycerin, the overall effect is that the glycerin will spill.

The Schwarzschild radius is a measure of the event horizon of a black hole, which is the point of no return beyond which nothing, not even light, can escape. It is named after the German physicist Karl Schwarzschild who first calculated it in 1916.

The formula for calculating the Schwarzschild radius is given by Rs = 2GM/c^2, where Rs is the Schwarzschild radius, G is the gravitational constant, M is the mass of the black hole, and c is the speed of light.

For a 10 solar mass black hole, we can plug in the values into the formula and get Rs = 29.96 billion km, which is approximately 30 billion km. This means that the event horizon of a 10 solar mass black hole is a sphere with a radius of 30 billion km.

To put this into perspective, the distance between the Earth and the Sun is about 150 million km, which means that the event horizon of a 10 solar mass black hole is about 200 times the distance between the Earth and the Sun.

In summary, the Schwarzschild radius of a 10 solar mass black hole is 30 billion km. This is an important measure of the size of a black hole and helps us understand the behavior of matter and energy around it.

(a) The frequency of the oscillation is approximately 2.5 Hz.

(b) The speed of the object, when it is 15 cm below the initial position, is approximately 0.55 m/s.

(c) The mass of the first object is approximately 19 g.

(d) The new equilibrium (rest) position with both objects attached to the spring is approximately 11 cm below yi.

(a) The frequency of oscillation can be found using the formula:

f = 1 / (2π) √(k/m)

where k is the spring constant and m is the mass of the object attached to the spring. Since the spring is massless, m only refers to the mass of the object attached to the spring. At the equilibrium position, the weight of the object is balanced by the restoring force of the spring. Therefore, we have:

mg = kΔL

where g is the acceleration due to gravity, ΔL is the extension of the spring from its rest length, and k is the spring constant. Solving for k, we get:

k = mg / ΔL

Substituting this value of k in the formula for frequency, we get:

f = 1 / (2π) √(mg / mΔL)

Canceling out the mass of the object, we get:

f = 1 / (2π) √(g / ΔL)

Substituting the given values, we get:

f ≈ 1 / (2π) √(9.8 m/s² / 0.22 m) ≈ 2.5 Hz

(b) The speed of the object can be found using the conservation of energy. At the equilibrium position, all the energy is potential energy. At a distance y below the equilibrium position, the potential energy is:

U = ½ k(y + ΔL)²

The kinetic energy at this position is:

K = ½ mv²

where v is the velocity of the object. Since energy is conserved, we have:

U = K

Substituting the values of U and K, and solving for v, we get:

v = √(2kΔL - 2ky)

Substituting the given values, we get:

v ≈ √(2 × 0.22 N/m × 0.22 m - 2 × 0.22 N/m × 0.15 m) ≈ 0.55 m/s

(c) When the mass of the system doubles, the frequency of oscillation becomes half. The frequency of oscillation can be expressed as:

f = 1 / (2π) √(k / m)

where k is the spring constant and m is the mass of the system. If the mass of the first object is m₁, then the mass of the system when the second object is attached is m₁ + 0.23 kg. We can express the new frequency as:

f/2 = 1 / (2π) √(k / (m₁ + 0.23 kg))

Dividing this equation by the previous equation and simplifying, we get:

√(m₁ / (m₁ + 0.23 kg)) = 2

Solving for m₁, we get:

m₁ ≈ 0.019 kg

(d) When two objects of masses m₁ and m₂ are attached to the spring, the extension of the spring from its rest length is:

ΔL = (m₁ + m₂)g / k

At the equilibrium position, the weight of the two objects is balanced by the restoring force of the spring. Therefore, we have:

(m₁ + m₂)g / k = 11 cm

(a) The angular velocity ω is the derivative of the angular position θ with respect to time t:

ω = dθ/dt

Taking the derivative of the given equation for θ, we get:

ω = 5.2t - 0.6t²

To find the maximum angular speed, we need to find the time at which ω is maximum. This occurs when the derivative of ω with respect to t is zero:

dω/dt = 5.2 - 1.2t = 0

Solving for t, we get t = 4.333 seconds. Substituting this value of t back into the equation for ω, we get:

ω(max) = 5.2(4.333) - 0.6(4.333)² = 10.4 rad/s

(b) The tangential velocity v of a point on the rim of the roller is given by:

v = rω

where r is the radius of the roller. Substituting the given values of r and ω(max) into this equation, we get:

v(max) = (9/2) * 10.4 = 46.8 m/s

Sam travels 910.6 meters before he finally coasts to a stop.

To solve this problem, we need to find the distance traveled by Sam during the 9.0 s when the skis were powered and then add the distance traveled during the coasting phase until he stops.

First, let's find the acceleration of Sam during the powered phase:

The net force on Sam is the force of thrust minus the force of friction:

net force = thrust - friction

net force = [tex]190 N - (0.1)(79 kg)(9.81 m/s^2) = 111.23 N[/tex]

Using Newton's second law, we can find the acceleration of Sam:

net force = mass x acceleration

111.23 N = 79 kg x acceleration

acceleration = 1.41 m/s^2

The distance traveled during the powered phase is given by:

distance powered = initial velocity x time + 0.5 x acceleration x time^2

The initial velocity is zero, so the distance traveled during the powered phase is:

distance powered = 0.5 x acceleration x time^2

distance powered = 0.5 x 1.41 m/s^2 x (9.0 s)^2

distance powered = 56.9 m

Now Sam coasts until he stops. During this phase, the only force acting on him is friction, so we can use the following equation to find the distance traveled:

distance coasting = initial velocity x time + 0.5 x friction x time^2

The initial velocity is the velocity Sam had at the end of the powered phase. To find this, we use the equation:

velocity = acceleration x time

velocity = 1.41 m/s^2 x 9.0 s

velocity = 12.7 m/s

So the distance traveled during the coasting phase is:

distance coasting =[tex]12.7 m/s x t + 0.5 x (0.1)(79 kg)(9.81 m/s^2) x t^2[/tex]

We want to find the total distance traveled, so we need to add the distance traveled during the powered phase to the distance traveled during the coasting phase:

total distance = distance powered + distance coasting

total distance = 56.9 m + 853.7 m

total distance = 910.6 m

Therefore, Sam travels 910.6 meters before he finally coasts to a stop.

The angular velocity of gear B after A undergoes an angular displacement of 10 revolutions, measured counterclockwise, is 11.2 rad/s (counterclockwise) to three significant figures.

Angular displacement is a measure of the change in the position of an object that is rotating about a fixed axis. It is the angle through which an object has rotated, measured in radians or degrees, and is defined as the final angular position minus the initial angular position. Angular displacement can be positive or negative, depending on the direction of rotation, and is usually measured in radians.

First, let's convert the angular displacement of 10 revolutions to radians:

10 rev * 2π rad/rev = 20π rad

Next, we can use the following kinematic equation to solve for the final angular velocity of gear A:

ωf^2 = ωi^2 + 2αΔθ

where ωi is the initial angular velocity of gear A, α is the angular acceleration of gear A, and Δθ is the angular displacement of gear A.

Substituting the given values:

ωf^2 = (11 rad/s)^2 + 2(2 + (0.006 rad/s^2)^2)(20π rad)

ωf^2 = 121 + 0.072416(20π)

ωf^2 = 121 + 4.5513

ωf^2 = 125.5513

ωf = 11.214 rad/s

Now we can use the gear ratio to find the angular velocity of gear B. Let's assume that gear A and gear B have the same number of teeth, so the gear ratio is 1:1. The angular velocity of gear B is equal to the angular velocity of gear A:

ωB = ωf = 11.214 rad/s

Therefore, Gear B's angular velocity, measured anticlockwise after gear A has undergone an angular displacement of 10 revolutions, is 11.2 rad/s (anticlockwise), to three significant numbers.

This means that an electron has a negative charge and a proton has a positive charge. The charge of an object is determined by the number of electrons and protons it has. If an object has an equal number of electrons and protons, it is said to be neutral and has a charge of zero.

The charge of an object can be measured using an instrument called an electrometer. Conductors, such as metals, have a high degree of conductivity and can easily transfer charge. In contrast, insulators have a low degree of conductivity and do not easily transfer charge.

The SI unit of conductance is the siemens (S), which is the reciprocal of resistance (ohms). The conductance of a material is determined by its ability to allow the flow of electric current. The concentration of charged particles in a material can affect its conductivity. For example, increasing the concentration of ions in an electrolyte solution can increase its conductivity.

The property of the quasar's spectrum that is critical in order to determine its distance is the redshift. Redshift is the shift in the wavelengths of light emitted by the quasar towards longer (redder) wavelengths due to the expansion of the universe.

By measuring the amount of redshift in the quasar's spectrum, astronomers can determine its distance using Hubble's Law. The greater the redshift, the greater the distance of the quasar from Earth.

The property of a quasar's spectrum that is critical for determining its distance is its redshift. Astronomers study the spectrum of a quasar and measure its distance by analyzing the redshift, which indicates the extent to which the quasar's light is stretched towards longer, redder wavelengths due to the expansion of the universe. The greater the redshift, the farther away the quasar is.

If the slit spacing becomes smaller, the spacing of the bright spots of a diffraction pattern will get larger.

Diffraction occurs when light passes through a small opening, causing it to bend and create a pattern of bright and dark fringes on a screen. The spacing between these fringes depends on the light's wavelength and slit spacing. Bright spot spacing is directly proportional to wavelength and inversely proportional to slit spacing. As slit spacing decreases, the diffraction angle increases, causing the distance between bright spots to increase. Therefore, if slit spacing becomes smaller, bright spot spacing increases. Diffraction is observed in various fields, including optics and X-ray crystallography, and is crucial for understanding wave behavior and interactions with matter.

The subsequent force on the window would be 1 N less than the

original force, which is a negligible difference.

Assuming that the pressure difference is acting uniformly on the entire

surface of the rectangular window, the subsequent change in force on

the window will be negligible since the change in pressure is only 1%

(0.01 atm).

The force on the window is given by the equation:

F = P × A

Where F is the force, P is the pressure, and A is the area of the window.

If the area of the window remains constant, then the force is directly

proportional to the pressure.

Therefore, a 1% decrease in pressure will result in a 1% decrease in force

on the window. For example, if the original force on the window was 100

N at 1 atm, then the subsequent force on the window at 0.99 atm would

be:

F = P × A = (0.99 atm / 1 atm) × 100 N = 99 N

So the subsequent force on the window would be 1 N less than the

original force, which is a negligible difference.
