1. a 0.42-kg object with an initial velocity of 3.40 m/s in the positive x-direction is acted on by a force in the direction of motion. the force does 6.50 j of work. what is the final velocity of the object?(neglect friction)

Answers

Answer 1

The final velocity of the object is 8.96 m/s. The result is obtained by using the formula for work which equal to change in kinetical energy.

How to find work done on a moving object?

The force acting on the object is doing work on the object, which is equal to the change in kinetic energy of the object. We can use the following formula to solve for the final velocity.

Change in Kinetic Energy = Work

½m (v₁ - v₀)² = W

We have

m = 0.42 kgv₀ = 3.4 m/sW = 6.5 J

Find the final velocity! (v₁ = ?)

Using the equation above, we can solve for the final velocity.

½(0.42) (v₁ - 3.4)² = 6.5

(v₁ - 3.4)² = 30.95

v₁ - 3.4 = √30.95

v₁ = 5.56 + 3.4

v₁ = 8.96

Hence, the final velocity of the object is 8.96 m/s.

suppose a 20.0-kg monkey climbs a vine. what is the tension in the vine if they climbs at a constant speed?

Answers

The tension in the vine if a monkey climbs a vine at a constant speed is 0 Newton.

The magnitude of tension force depends on the amount of force applied to the ends of the string or rope, as well as the properties of the string or rope itself, such as its length, thickness, and elasticity.

Tension force is often used in mechanical systems to transfer forces or transmit power. For example, a cable used to lift a heavy object will experience tension forces as it resists the weight of the object. Similarly, a belt in a car engine experiences tension forces as it transfers power from the engine to the wheels.

Mass of the monkey, m = 20 kg.

Let the tension in the vine be T.

The acceleration of the monkey is zero since the speed is constant.

Using the second law of motion,F = ma

Here, acceleration, a = 0F = 0N = ma= 20 x 0= 0 N

find the net force on a 30.0 nc charge located at the origin by two other charges. one is -50.0 nc located at (-5.0 m, 2.0 m) and 40.0 nc located at (3.0 m, 1.0 m).

Answers

The net force on a 30.0 nc charge located at the origin by two other charges is the vector sum of the forces exerted by the two other charges. The force exerted by the first charge, -50.0 nC located at (-5.0 m, 2.0 m), is given by:

F1 = (k*q1*q2)/r2, where

k = 8.99 x 109 N m2/C2q1 = -50.0 ncq2 = 30.0 ncr = square root of (5.02 + 2.02) = 5.385

Therefore,

F1 = (8.99 x 109 N m2/C2)*(-50.0 nc)*(30.0 nc)/(5.3852) = 2.38 x 10-2 N

Similarly, the force exerted by the second charge, 40.0 nc located at (3.0 m, 1.0 m), is given by:

F2 = (k*q1*q2)/r2, where

k = 8.99 x 109 N m2/C2q1 = 40.0 ncq2 = 30.0 ncr = square root of (3.02 + 1.02) = 3.162

Therefore,

F2 = (8.99 x 109 N m2/C2)*(40.0 nc)*(30.0 nc)/(3.1622) = 4.58 x 10-2 N

The net force is the vector sum of F1 and F2 and can be calculated as follows:

F net = F1 + F2 = 2.38 x 10-2 N + 4.58 x 10-2 N = 7.00 x 10-2 N

Therefore, the net force on a 30.0 nc charge located at the origin by two other charges is 7.00 x 10-2 N.

if 22.5L of nitrogen at 748 mm Hg are compressed to 725 mm hg at constant temperature what is the new volume?

Answers

The new volume is approximately 23.16 L when the nitrogen gas is compressed from 748 mmHg to 725 mmHg at constant temperature.

Use the combined gas law to determine the relationship between a gas's pressure, volume, and temperature:

P1V1/T1 = P2V2/T2

where the gas's starting pressure, volume, and temperature are P1, V1, and T1, and its ultimate pressure, volume, and temperature are P2, V2, and T2.

The equation may be made simpler by saying: since the temperature is constant.

P1V1 = P2V2

Substituting the given values, we get:

725 mmHg × V2 = 748 mmHg × 22.5 L

Solving for V2, we get:

V2 = (748 mmHg × 22.5 L) / 725 mmHg

V2 = 23.16 L

you have learned that in the earth-moon system, the gravitational pull of earth's tidal bulges causes the moon to spiral away from earth. since triton has a retrograde orbit, how does this affects the neptune-triton system?

Answers

You have learned that in the earth-moon system, the gravitational pull of earth's tidal bulges causes the moon to spiral away from earth. since triton has a retrograde orbit, this affects the neptune-triton system to be unstable, making it difficult for the other moons to maintain stable orbits.

Triton is a large moon of Neptune, about 1,680 miles (2,700 kilometers) in diameter. Its orbit is tilted and is also in the opposite direction of the other moons in the solar system's plane. Triton's orbit is retrograde, which means it is moving in the opposite direction to Neptune's rotation. When an object orbits in the opposite direction to the rotation of the planet it orbits, it is said to have a retrograde orbit. This is because the gravitational attraction between the two objects is weaker when they are moving in opposite directions. Because of this, Triton's retrograde orbit has a destabilizing effect on Neptune's other satellites.

The retrograde orbit of Triton causes the Neptune-Triton system to be unstable, making it difficult for the other moons to maintain stable orbits. The gravitational force of Triton is pulling away at the other moons, causing them to move erratically, some being pushed further away from Neptune and others being pulled closer. In addition to the destabilizing effect, Triton's retrograde orbit has caused it to move closer to Neptune over time, where it is thought that it will eventually break apart, forming a ring around the planet.

Answers

The primary mirror of an astronomical telescope is often shaped and polished to a parabolic shape because a parabolic shape allows for the mirror to collect the most amount of light and focus the parallel rays of light to a single point for better image clarity.


The reason that the primary mirror of an astronomical telescope is often shaped and polished to a parabolic shape is to reduce spherical aberration.

What is an astronomical telescope?An astronomical telescope is an optical instrument that aids in the observation of remote objects by collecting electromagnetic radiation such as visible light. It consists of two primary components: a primary mirror or lens that gathers and focuses light, and an eyepiece or camera that magnifies and projects the image formed by the primary.

A parabolic shape is a mirror or lens that has a curve that is more curved in the center than at the edges, and it is often used in astronomical telescopes to reduce spherical aberration. Spherical aberration is an optical defect that causes the image of a point source to become fuzzy and blurred. It occurs when the rays passing through the edges of a spherical lens or mirror become focused at a different distance than those passing through the center. This causes the image to be blurred around the edges, which makes it difficult to view small or distant objects. Parabolic mirrors are used to correct this problem because they are designed to focus all incoming light to a single point, resulting in a sharper and clearer image.

A 9.00 kg mass is moving to the right with a velocity of 14.0 m/s. A 12.0 kg mass is moving to the left with a velocity of 5.00 m/s. Assuming that these two balls have a head on collision and stick together, what will be the final velocity of the combination? (3.1 m/s)

Answers

Answer:

5.95 m/s to the right

Explanation:

Before the collision, the momentum of the system is given by:

p = m1v1 + m2v2

p = (9.00 kg)(14.0 m/s) + (12.0 kg)(-5.00 m/s)

p = 125.0 kg m/s (to the right)

During the collision, the two masses stick together, so their final velocity will be the same. Let's call this final velocity vf. The momentum of the system after the collision is given by:

p' = (m1 + m2)vf

p' = (9.00 kg + 12.0 kg)vf

p' = 21.0 kg vf

Since momentum is conserved in the collision (there are no external forces acting on the system), we can set p = p' and solve for vf:

125.0 kg m/s = 21.0 kg vf

vf = 5.95 m/s (to the right)

Therefore, the final velocity of the combined masses after the collision is 5.95 m/s to the right.

The phenomenon that occurs when the time on the clock of an astronaut on a spaceship passing at 0.25c runs slower than does time on a patent clerk's clock is called time dilation.

Time dilation:Time dilation is a phenomenon in which time passes at a slower rate for an observer in relative motion compared to a stationary observer, as predicted by the theory of relativity.

It also is a consequence of the theory of relativity, which predicts that time appears to run slower for objects that are moving relative to an observer.

In this case, the astronaut's clock appears to be running slower than the patent clerk's clock because the astronaut is moving relative to the patent clerk.

This effect becomes more pronounced as the speed of the spaceship approaches the speed of light.

what is the pressure of a fluid that comes out of a pipe that was closed on both ends, but then is opened up one end

Answers

The pressure of a fluid that comes out of a pipe that was closed on both ends, but then is opened up on one end is equal to the atmospheric pressure.

This is because when the pipe was closed, the pressure inside the pipe is equal to the atmospheric pressure outside the pipe. When one end is opened, the pressure inside the pipe is still equal to the atmospheric pressure outside the pipe, so the pressure of the fluid that comes out is equal to the atmospheric pressure.


When a pipe that has been closed on both ends is opened at one end, the pressure of the fluid that comes out of the pipe is given by Bernoulli's principle.

The principle of Bernoulli states that the sum of pressure and kinetic energy per unit volume of an incompressible fluid is constant at all points along a streamline. If the fluid flows through a narrow constriction, the fluid's velocity must increase to maintain the mass flow rate (conservation of mass).

Bernoulli's principle can be represented mathematically as:

P + 1/2ρv² + ρgh = constant

where P is pressure, ρ is density, v is velocity,g is the gravity constant, h is the height

Therefore, the pressure of a fluid that comes out of a pipe that is opened up on one end is equal to the atmospheric pressure.

Vector V is a vector with a magnitude of 6 miles per hour in a northwesterly direction on the coordinate plane. The magnitude of vector V is 6, and its direction is northwesterly.

What are the magnitude and direction of vector?

cos θ = x / r, sin θ = y / r,

tan θ = y / x,

where θ is the angle between the vector and the x-axis, x and y are the coordinates of the vector on the coordinate plane, and r is the magnitude of the vector.

The magnitude of vector V: The magnitude of vector V is 6 miles per hour.

Therefore, r = 6.

The direction of vector V: the angle θ, the x and y components of vector V must be determined.

The angle between vector V and the x-axis is 45 degrees since the vector is going northwesterly, so the angle is halfway between 90 degrees for directly up and 0 degrees for directly to the right. Because the angle is 45 degrees, the x and y components are equal.

Therefore, the x and y components are both 6 / √2. Using

cos θ = x / r and sin θ = y / r,

The values of cos θ and sin θ.cos θ

 = 6 / √2 / 6

 = 1 / √2, and

sin θ = 6 / √2 / 6

Rearrange Coulomb's law and find the magnitude of each charge.Express your answer to two significant figures and include the appropriate units.Two point charges are separated by 5.0 cm . The attractive force between them is 16 N . Suppose that the charges attracting each other have equal magnitude.

Answers

Each charge has a magnitude of about 1.3×C (to two significant numbers), or 13 C.

To find the magnitude of each charge, we can rearrange Coulomb's law as follows:

Coulomb's law: F = k * |q1 * q2| / r²

Here, F is the force between two charges (16 N), k is Coulomb's constant (8.99 × 10⁹ N·m²/C²), q1 and q2 are the magnitudes of the two charges, and r is the distance between the charges (5.0 cm or 0.050 m). Since the charges have equal magnitude, we can say q1 = q2 = q.

Rearranging the formula for q:

q² = F * r² / k

Now, we can plug in the given values and solve for q:

q² = (16 N) * (0.050m)² / (8.99 × 10⁹ N·m²/C²)

q²≈ 1.77 × 10⁹ C²

q ≈ √(1.77 ×10⁹ C²)

q ≈ 1.33 × 10⁵C

So, the magnitude of each charge is approximately 1.3 ×10⁵ C (to two significant figures) or 13 μC.

The image below is a sketch of two-slit diffraction of light. Narrow slits at A and B act as wave sources, and waves interfering in various phases are shown at C, D, E, and F.

Answers

The distance 'd' of the equation represents the distance between the two slits, A and B. This is because the equation is for the double-slit experiment, which is based on two narrow slits acting as wave sources.

This is the distance between the two sources that act as wave sources, which interfere with each other to create the diffraction patterns C, D, E, and F. The light bands between D and E and F are not part of the equation and do not represent the 'd' of the equation.

The equation: λ/d = x/L represents the image form between A and B.  This distance is used in the equation to calculate the angle of diffraction.

Diffraction is the process by which light or sound waves bend around corners or obstacles and spread out when passing through narrow openings.

an electric train operates on 625 v. what is its power consumption when the current flowing through the train's motor is 2,110 a?

Answers

The power consumption of the train's motor is 1,317,500 W.

Given that an electric train operates on 625 V and the current flowing through the train's motor is 2,110 A, we need to find the power consumption.

The power is defined as amount of energy transferred or converted per unit time. The electric power is given by the electric current times the voltage.

The formula to calculate power consumption is:

Power = Voltage x Current

In the given case, Voltage = 625V and Current = 2,110 A.

Substituting the given values in the formula, we get,

Power = 625 V x 2,110 A

Power = 1,317,500 W

Therefore, the power consumption of the electric train is 1,317,500 W.
