Respuesta :
1. Power = work done / time =200/20 = 10W. 2. Power = work done / time = 50/4 = 12.5W. So second one involves more power.
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 :
- 200j of work done in the 20s.
- 50j of work done in the 4s.
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:
[tex]\rm Power = \dfrac{Work}{Time}[/tex]
Strep 3 - When 200j of work is done in 20 sec, then the power is given by:
[tex]\rm Power = \dfrac{200}{20}[/tex]
Power = 10 W
Step 4 - When 50j of work is done in 4 sec, then the power is given by:
[tex]\rm Power = \dfrac{50}{4}[/tex]
Power = 12.5 W
So, the situation that gives more power is 50j of work done in 4s.
