Answer:
It takes 4 minutes for the student to do this. What is the power input?
Explanation:
Answer:
It takes 4 minutes for the student to do 24J of work on a chair
Explanation:
From the above question,
They have given :
Workdone = 24 J
Force = 12 N
Here we need to determine the amount of power used.
The power is defined as the rate at which work is done, which means that power is equal to the amount of work done divided by the time taken to do the work.
The formula for power is:
Power = Work / Time
Thus, the student did 24 J of work on the chair by applying a force of 12 N and moving it 2 m. Also they haven't mentioned how long it took the student to do this work. Without the time taken, we cannot determine the power used.
Power = 24 J / Time
So, to solve for time, we can rearrange the formula as:
Time = Work / Power
So, to calculate the power used, you need to ask for the amount of time taken by the student to do the work on the chair.
Hence, It takes 4 minutes for the student to do 24J of work on a chair
