A person A does 500 J of work in 10 minutes and another person B does ...
> PA > PB
c) PA < />

To find the power delivered by each person, we can use the formula:

Power (P) = Work (W) / Time (t)

For person A:
PA = 500 J / 10 min = 50 J/min

For person B:
PB = 600 J / 20 min = 30 J/min

Comparing the values, we can see that:

a) PA ≠ PB (50 J/min ≠ 30 J/min)
So, option a) is incorrect.

b) PA > PB (50 J/min > 30 J/min)
So, option b) is incorrect.

c) PA < pb="" (50="" j/min="" />< 30="" j/min)="" />
So, option c) is correct.
