Power is the rate at which energy is transformed. a person is limited in the total work he or she can do only by the total energy required. the si unit of power is the horsepower. a person is limited in the total work he or she can do by the rate at which energy can be transformed. the si unit of power is the watt. power is the rate at which work is done.

Power is the rate at which energy is transformed.

The SI unit of power is the watt.

Power is the rate at which work is done.

Explanation:

In this question we have to choose the statements related to Power that are True.

In this sense, Power is the speed with which work is done. Its unit is Watts (), being .  

Power is mathematically expressed as:

Where is the time during which work is performed.

On the other hand, the Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path. It is a scalar magnitude, and its unit in the International System of Units is the Joule (like energy). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter ( ).

So, according to this explanation, the true statements are:

Power is the rate at which energy is transformed.

The SI unit of power is the watt.

Power is the rate at which work is done.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
