Evaluate which of the following situations involves more power: 200j of work done in 20s or 50j of work done in 4s??
The situation that gives more power is 50j of work done in 4s and this can be determined by using the formula of power.
Given :
The following steps can be used in order to determine the correct situation that involves more power:
Step 1 - The formula of power can be used in order to determine the correct situation that involves more power.
Step 2 - The formula of power is given below:
\(\rm Power = \dfrac{Work}{Time}\)
Strep 3 - When 200j of work is done in 20 sec, then the power is given by:
\(\rm Power = \dfrac{200}{20}\)
Power = 10 W
Step 4 - When 50j of work is done in 4 sec, then the power is given by:
\(\rm Power = \dfrac{50}{4}\)
Power = 12.5 W
So, the situation that gives more power is 50j of work done in 4s.
