Power can be defined as the rate at which work is accomplished.

Option D is the correct answer.

<h3></h3><h3>Power </h3>

The work done by an object in a given time interval is called the power of that object.

Suppose an external force F is applied to any object for the time interval T seconds. Due to this external force, the object will perform some amount of work for the time T seconds. This work W done by the object for the time interval T seconds is called the power of that object.

Power can be defined in mathematical term which is given below.

P = \dfrac {W}{T} \;\rm Watts

Thus the power can also be defined as the work done by the object per unit time interval.

Hence we can conclude that option D is the correct answer.

To know more about power, follow the link given below.

A fish (6 kg) is being yanked vertically upward out of the water and the fishing line breaks. If the line is rated to a maximum
ANEK [815]

Answer:

15.2 m/s²

Explanation:

Acceleration: This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²

From the question,

F-W = ma......................... Equation 1

Where F = Tension on the line, W = weight of the fish, m = mass of the fish, a = acceleration of the fish.

But,

W = mg........................ Equation 2

Where g = acceleration due to gravity.

Substitute equation 2 into equation 1

F-mg = ma

make a the subject of the equation

a = (F-mg)/m.................... Equation 3

Given: F = 150 N, m = 6 kg,

Constant: g = 9.8 m/s²

Substitute into equation 2

a = [150-(6×9.8)]/6

a = (150-58.8)/6

a = 91.2/6

a = 15.2 m/s²

Hence the minimum acceleration of the fish = 15.2 m/s²

Construct an argument to support the statement "You experience frictional forces when you walk down the hall." Describe what wou
xz_007 [3.2K]

Explanation:

Frictional force is need for walking and to allow motion. Without friction, walking and motion wouldn't be possible.

Frictional force is a force that opposes the direction of the motion of a body.

It is force that opposes motions and it is directed towards the opposite side of motion.

Without the force of friction within our feet and the ground, we will continue to slide indefinitely and not be able to have grip of our motion.

Friction restricts and helps to control motion.
