## What is the correct definition of power?

Answer: Power is the rate at which work is done. Explanation: Power is defined as the rate at which the work is done or the rate at which heat is transferred. We also can define this as the amount of energy converted or transferred by unit of time.

## How is work and power similar?

Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

## What is energy in terms of power?

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second.

## How do you find time with power?

Determine the time in which the work will be done. Here, we can take t = 60 s . Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .

## What is the power required?

There are two types of power requirements based on a number of factors, least of which is the size of the overall project. There is power as in the amount of computing power, as in the amount of microprocessors and their speed, and the amount of peak watts from the computing power supply.

## How do you tell if a number is a power of 4?

A simple method is to take log of the given number on base 4, and if we get an integer then number is power of 4. 2. Another solution is to keep dividing the number by 4, i.e, do n = n/4 iteratively. In any iteration, if n%4 becomes non-zero and n is not 1 then n is not a power of 4, otherwise n is a power of 4.
