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
