Explanation:

The velocity of the football thrown is approximately 23.76 meters per second.

Momentum is simply the product of the mass of an object and its velocity.

This is expressed as;

P = m × v

Where m is the mass of the object and v is its velocity.

Given that;

Plug the given values into the above formula and solve for v.

P = m × v

v = P / m

v = 10.1kgm/s / 0.425kg

v = 23.76 m/s

Therefore, the velocity of the ball is 23.76 m/s.

The 400 A current flowing through the wire will be going the other way from the other wire.

An electroscope is a straightforward instrument that consists of a metal piece protruding from a glass jar with thin metal leaves suspended inside. This design demonstrates the electrostatic repulsive force. The leaves spread apart by the Coulomb force when a charged body touches the external metal piece.

We will apply the equation to determine the current in the other wire

F/l = µ₀I₁I₂/2πr and solve it for I₂.

The other wire's current will flow in the opposite direction to the first one because the force is repulsive.

I₂ = F.2πr/µ₀I₁l

I₂ = 4×2π×0.05m/4π×10⁻⁷T.m/A×1000A×2.50m

Magnetic field strength is a quantitative measure of the strength or weakness of a magnetic field.

According to the displacement current and the Biot-Savart law, the displacement current and magnetic field can be calculated.

radius of the circular plate = R = 16.0

rate of charge =  (dq/dt) = 8 C/s

displacement current id = (dq/dt) * [tex]\pi r^{2}[/tex] / [tex]\pi R^{2}[/tex]

since r > R therefore in displacement current the formula can be changed as

The word "force" has a specific meaning in science. At this level, calling a force a shove or a pull is entirely appropriate. A charge is not really something an object "has in it" or that it "contains." One thing experiences a force from another. Living organisms or inanimate objects are not the only things that can be considered forces. Every time two items interact, a force is exerted on every one of the objects. The force is no longer felt by the two objects when the interaction ends.

Answer:

The Conservation of Energy states that:

Initial Kinetic Energy + Initial Potential Energy = Final Kinetic Energy + Final Potential Energy

So we can write

[tex]mgh_{i}+\frac{1}{2}mv_{i} ^{2}=mgh_{f}+\frac{1}{2}mv_{f} ^{2}[/tex]

We can cancel the common factor of [tex]m[/tex] which leaves us with

[tex]gh_{i}+\frac{1}{2}v_{i} ^{2}=gh_{f}+\frac{1}{2}v_{f} ^{2}[/tex]

Lets solve for [tex]v_f[/tex]

[tex]gh_{i}+\frac{v_{i} ^{2}}{2}=gh_{f}+\frac{v_{f} ^{2}}{2}[/tex]

Subtract [tex]gh_f[/tex] from both sides of the equation.

[tex]gh_{i}+\frac{v_{i} ^{2}}{2}-gh_{f}=\frac{v_{f} ^{2}}{2}[/tex]

Multiply both sides of the equation by 2.

[tex]2(gh_{i}+\frac{v_{i} ^{2}}{2}-gh_{f})={v_{f} ^{2}[/tex]

Simplify the left side.

Apply the distributive property.

[tex]2(gh_{i})+2\frac{v_{i} ^{2}}{2}+2(-gh_{f})={v_{f} ^{2}[/tex]

Cancel the common factor of 2.

[tex]2gh_{i}+v_{i} ^{2}-2gh_{f}={v_{f} ^{2}[/tex]

Take the square root of both sides of the equation to eliminate the exponent on the right side.

[tex]{v_{f}=\sqrt{2gh_{i}+v_{i} ^{2}-2gh_{f}}[/tex]

We are given [tex]g,v_{i},h_{i},h_{f}[/tex].

We can now solve for the final velocity.

The height that a circular hoop should be released can be calculate as follows:

Generally the equation for the potential energy of the sphere is mathematically given as

mgh= 1/2Iw² =1/2 mv²

where,

inertia of sphere

I = 2/5 mr²

and

angular velocity

w = v/r

therefore, we can input inertia of sphere and angular velocity to potential energy equation

mgh= 1/2Iw² =1/2 mv²

mgh = 1/2 ( 2/5mr²) ((v/r)² + 1/2mv²

mgh = 1/2 ( 2/5(v/r)²mr²) + 1/2mv²

mgh = 1/5 mv² +  1/2 mv²

Work can be described as the energy utilized when a force is exerted to move a body through a specific distance. The work done describes both the exerted force as well as the displacement of the object.

The action of the applied force is to move a system in a straight line in the direction of the exerted force over a distance 'd'.

W= F ×d

Where 'd' is the displacement by an object, F' is the exerted force, and W is work done.

Given the force experienced by the object B is greater than object A:
