The bowling ball has a rotating kinetic energy of 8.573 J and a total velocity of 134.573 J.

A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the energy transfer, is done on it by exerting a net force. The word "kinetic" derives from the Greek "kinesis," which means motion. Any direction can be used to move it. As can be seen, kinetic energy rises with increasing mass and/or speed, and it stays unchanged if an object slows down or accelerates up.

To calculate rotational kinetic energy:

Rotational kinetic energy = (1/2) * I * ω^2

where I is the intertia of solid

I = (2/5) * m * r^2, m is the mass and r is radius

Substituting the given values, we get:

I = (2/5) * 7 kg * (0.109 m)^2

I = 0.00265 kg * m^2

The angular velocity of the ball ω = v / r

let v is the linear velocity of the ball.

Substituting the given values, we get:

ω = 6 m/s / 0.109 m

ω = 55.046 rad/s

by substituting this values into formulae we get

Rotational KE= (1/2) * 0.00265 kg * m^2 * (55.046 rad/s)^2

Rotational KE = 8.573 J

Therefore, the rotational kinetic energy of the bowling ball is 8.573 J.

The translational kinetic energy can be calculated as:

Translational kinetic energy = (1/2) * m * v^2

Substituting the given values, we get:

Translational KE= (1/2) * 7 kg * (6 m/s)^2

Translational KE = 126 J

Therefore, the total KE of the ball is:

Total kinetic energy = Rotational kinetic energy + Translational kinetic energy

Total KE = 8.573 J + 126 J

Total kinetic energy = 134.573 J

Therefore, the total kinetic energy of the ball is 134.57

The force with which the Earth is attracted towards the person is equal to the same force of 120 lbs.

This is due to the law of universal gravitation. This law states that any two objects in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, the Earth and the person both experience a force of 120 lbs due to their mutual attraction.

The law of universal gravitation states that any two objects in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Static friction is a force which keeps an object at rest. Static friction can be harmful as it releases energy in the form of heat due to rubbing of two bodies.

Static friction is a force which keeps an object at the state of rest. Static friction can be defined as the friction which is experienced when the individuals try to move a stationary object on a smooth surface, without actually triggering any relative motion between the two objects or body and the surface on which it is moving.

In static friction, the frictional force resists the force which is applied to an object in motion, and the object which remains at the state of rest until the force of static friction is overcome. In the kinetic friction, the frictional force resists the motion of an object. This produces heat energy.

The magnitude of the electric force on the raindrops (acquire an electric charge as they fall, suppose a 2.5-mm-diameter drop has a charge of +15 pC) droplet compare to the weight force = 204.134 x 10⁻⁶ N.

So, the weight of the droplet is more than the electric force.

To determine the electric force on the charge, use the equation:

The electric force on the charge = charge x electric field

= (15 x 10⁻¹² C) x 100

= 15 x 10⁻⁹ N

As force on positive charge operates in the direction of the electric field, it will go upward.

Determine the volume of the droplet:

V = 4/3 π R³

= 4/3 (2.5 x 10⁻³ m)³

= 20.83 x 10⁻⁹ m³

The mass of the droplet:

mass = density x volume

= (1000) x (20.83 x 10⁻⁹ kg)

= 20.83 x 10⁻⁶

Hence,

The weight = m x g

= (20.83 x 10⁻⁶) x (9.8)

The work that the electric force do on q₀ during its motion from A to B is + 0.792 J.

When an item is pushed across a specific distance by an external force, work is the quantity of energy that is transmitted to the object.

In the given problem, distance between q₀ and q is:

d₁ = √2 x 7.00 cm = 9.90 cm

The distance between q₀ and the charge q is:

d₂ = √2 x 7.00 cm = 9.90 cm

The electric force between two charges is given by Coulomb's law:

F = k × q₁× q₂ / r²

where k is the Coulomb constant, q₁ and q₂ are the charges, and r is the distance between them.

At point A, the electric force on q₀ due to the charge q is:

F1 = k × q₀ × q / d₁²

= (9.0 x 10⁹ N·m²/C²) × (-1.00 × 10⁻⁶C) × (7.00 × 10⁻⁶ C) / (9.90 x 10⁻² m)²

= -4.002 N

The negative sign indicates that the force is in the opposite direction to the displacement of q₀.

At point B, the electric force on q₀ due to the charge q is:

F2 = k × q₀ × q / d₂²

= (9.0 × 10⁹)× (-1.00 × 10⁻⁶) × (7.00 × 10⁻⁶) / (9.90 × 10⁻²)²

= -4.002 N

So, work done by a constant force:

W = F × d × cosθ

So the work done by the electric force on q₀ from A to B is:

W = F1 × d1 × cos(180) + F2 × d2 × cos(180) = (-4.002 N) × (9.90 × 10⁻² m) × (-1) + (-4.002 N) × (9.90 × 10⁻² m) × (-1) = 0.792 J

The positive value indicates that the work done by the electric force is in the direction opposite to the displacement of  q₀, which means that the electric force does negative work on q₀.

The ball will rise to a height of approximately 31.25 meters.

First we can use the concept of energy conservation. Initially, the baseball has kinetic energy due to its motion, and as it rises, this kinetic energy is converted into potential energy due to its increased height.

The sum of the kinetic and potential energy of the baseball must remain constant, so we can use this principle to determine the maximum height reached by the ball.

The formula for kinetic energy is:

KE = 0.5 x m x v^2

where m is the mass of the ball (0.4 kg) and v is the velocity of the ball (25 m/s).

The formula for potential energy is:

PE = m x g x h

where m is the mass of the ball, g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the ball.

Since the total energy is conserved, we can set the initial kinetic energy equal to the final potential energy and solve for h:

0.5 x m x v^2 = m x g x h

0.5 x 0.4 kg x (25 m/s)^2 = 0.4 kg x 9.8 m/s^2 x h

h = (0.5 x (25 m/s)^2) / (9.8 m/s^2)

h = 31.25 m

v_r = 4 km/h - 2.8 km/h = 1.2 km/h

The distance the rower travels is 2 * 1500 m = 3000 m, or 3 km. Therefore, the time it takes for the rower to make the round trip is:

t_r = 3 km / 1.2 km/h = 2.5 hours

Now let's find the time it takes for the walker to make the round trip. The walker's velocity is 4 km/h, so the time it takes for them to walk 1500 m from A to B is:

t_w = 1500 m / 4 km/h = 0.375 hours

The walker then turns around and walks 1500 m back to A, which takes another 0.375 hours. Therefore, the total time it takes for the walker to make the round trip is:

t_w = 2 * 0.375 hours = 0.75 hours

(b) The internal energy produced in the battery during one charge-discharge cycle can be found by:
