The average force with which the ball was struck is 20 N.

We can use the impulse-momentum theorem to solve this problem. The impulse-momentum theorem states that the force acting on an object is equal to the change in momentum of the object divided by the time interval over which the change occurs:

F = Δp / Δt

where F is the average force, Δp is the change in momentum, and Δt is the time interval.

In this case, the change in momentum of the baseball is:

Δp = mΔv = (0.050 kg)(32 m/s) = 1.6 kg m/s

The time interval over which this change occurs is:

Δt = 0.080 s

Therefore, the average force acting on the baseball is:

F = Δp / Δt = (1.6 kg m/s) / (0.080 s) = 20 N

A wave's frequency varies when it moves from one medium to another. This is due to the fact that a wave's wavelength doesn't change when it enters a different medium, but its speed does. This is referred to as the frequency-wavelength relationship of the wave.

Based on the information provided in the table, the waves can be ranked from lowest energy to highest energy as follows: wave 1, wave 2, wave 3, and wave 4.

This is because wave energy is directly proportional to its amplitude and frequency, and in this case, the amplitude of wave 1 is the lowest, followed by wave 2, wave 3, and wave 4.
When a wave travels from one medium to another, its frequency changes.

This is because the speed of the wave changes when it enters a different medium, while its wavelength remains constant. This is known as the wave's frequency-wavelength relationship.

When the wave enters a denser medium, its speed decreases, and its frequency decreases as well. On the other hand, when the wave enters a less dense medium, its speed increases, and its frequency increases as well. Therefore, the change in media can affect the frequency of the wave.

A wheel with a 0.10-m radius is rotating at 35 rev/s. It then slows uniformly to 15 rev/s over a 3.0-s interval. The angular acceleration of a point on the wheel is C) -6.7 rev/s².

To find the angular acceleration of a point on the wheel, we will follow these steps:
1. Convert the initial and final angular velocities from rev/s to rad/s.
2. Calculate the angular acceleration using the formula: α = (ω[tex]_{final}[/tex] - ω[tex]_{initial}[/tex]) / [tex]time_{interval}[/tex]
Step 1: Convert rev/s to rad/s
Initial angular velocity (ω[tex]_{initial}[/tex]) = 35 rev/s * (2π rad/rev) = 70π rad/s
Final angular velocity (ω[tex]_{final}[/tex]) = 15 rev/s * (2π rad/rev) = 30π rad/s
Step 2: Calculate angular acceleration (α)
Time interval = 3.0 s
α = (ω[tex]_{final }[/tex]- ω[tex]_{initial}[/tex]) / [tex]time_{interval}[/tex] = (30π - 70π) / 3 = -40π / 3 rad/s²
To convert the angular acceleration back to rev/s², divide by (2π rad/rev):

Answer: 2.390 J (joules).

Explanation:

Given:

Mass of tennis ball = 0.051 kg

Velocity of tennis ball = 9.7 m/s

To find:

Kinetic energy of the tennis ball

Solution:

Using the formula for kinetic energy:

Kinetic energy = (1/2) * mass * velocity^2

Plugging in the values:

Kinetic energy = (1/2) * 0.051 kg * (9.7 m/s)^2

Kinetic energy = (1/2) * 0.051 kg * 94.09 m^2/s^2

Kinetic energy = 2.390 J

Therefore, the kinetic energy of a 0.051 kg tennis ball moving at 9.7 m/s is 2.390 J (joules).

The electric field decreases due to the polarization of the dielectric material.

When a dielectric material is inserted between the plates of a capacitor, it becomes polarized due to the electric field. The polarization of the dielectric creates an electric field in the opposite direction to the applied electric field, which reduces the net electric field between the plates.

The polarization occurs because the electric field causes the charges within the dielectric material to shift, creating a dipole moment. These induced dipoles produce an electric field that opposes the original applied electric field. The reduction in the electric field between the plates leads to an increase in the capacitance of the capacitor, which is the ability to store more charge for a given potential difference. This effect is the basis of the capacitor's ability to store electrical energy.

The pressure at the surface of the glycerin in the left arm of the u-shaped tube is equal to the pressure at the surface of the unknown liquid in the right arm. Since both arms are open to the air, the pressure at the surface of the glycerin is atmospheric pressure. Therefore, the pressure at the surface of the unknown liquid is also atmospheric pressure.
Using the formula P = ρgh, where P is pressure, ρ is density, g is acceleration due to gravity, and h is height, we can set up two equations:
P = ρ₁gh₁ (for the unknown liquid in the right arm)
P = ρ₂gh₂ (for the glycerin in the left arm)
Since the pressure is the same in both arms and g is the same for both liquids, we can set the two equations equal to each other:
ρ₁gh₁ = ρ₂gh₂
We are given that h₂ - h₁ = 12.0 cm. Substituting h₂ - h₁ for h₁ in the equation above, we get:
ρ₁g(h₂ - 12.0) = ρ₂gh₂
Simplifying, we get:
ρ₁ = (ρ₂gh₂) / (g(h₂ - 12.0))
We are given that the height of the unknown liquid in the right arm is 35.0 cm. Substituting the given values, we get:
ρ₁ = (ρ₂ x 9.81 x 35.0) / (9.81 x (35.0 - 12.0))

Kinetic energy (KE) is the energy of motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.

(a) The glider is initially at rest. As it is pushed against the launcher, the spring is compressed by a distance x. The work done by the spring on the glider is W = ½kx2. This energy is converted into kinetic energy of the glider. Thus, the speed of the glider is given by the equation
v = (2W/m)1/2 = x(k/m)1/2

(b) Momentum is conserved during the collision, so the impulse imparted to the glider is the same as the change in momentum of the glider. Since the glider is initially at rest, the change in momentum is equal to the final momentum. This is equal to the mass of the glider multiplied by its final speed, so the impulse is given by

I = mv = x(km)1/2

The Assertion mentioned in the question is that the compressive strength of a typical brittle material is significantly higher than its tensile strength.

This statement is correct because brittle materials are those materials that break easily upon the application of a force. Brittle materials do not have any plastic deformation region and have a limited range of elasticity.

Due to this, when a compressive force is applied to a brittle material, it tends to resist the force and does not break easily.

On the other hand, when a tensile force is applied to a brittle material, it tends to break easily as it does not have the ability to stretch.

However, the Reason mentioned in the question, which is not correct, states that the compressive forces act more uniformly across the cross-section of a brittle material than tensile forces.

A large force can produce a small torque when the force is applied perpendicular to the point of rotation, resulting in a shorter lever arm.

Conversely, a small force can produce a large torque when it is applied perpendicular to the point of rotation but at a greater distance from the pivot point, resulting in a longer lever arm. The torque produced by a force is calculated by multiplying the force by the distance from the pivot point, or lever arm. Thus, the amount produced depends on both the magnitude of the force and the distance from the pivot point. When a large force is applied perpendicular to the pivot point but at a short distance, the resulting torque is relatively small. Similarly, when a small force is applied perpendicular to the pivot point but at a greater distance, the result can be relatively large.
