Solutions: First Case
Power = Work done/Time taken
Here, Work done = 20 J
And, Time taken = 20 s
So, putting these values in the above formula, we get;
Power = 20 J/20 s
Power = 1 J/s or 1 W
Solutions: Second case
Power = Work done/Time taken
Here, Work done = 40 J
And, Time taken = 40 s
So, putting these values in the above formula, we get;
Power = 40 J/40 s
Power = 1 J/s or 1 W
Comparing Ratios :
Power = 1: 1
