case 1: 200/10=20 watt
case 2: 100/4= 25 watt
ratio= man/boy
= 20/25
= 4/5 = 4:5
The boy is delivering more amount of power than the man. The ratio of our delivered by the man to that by the boy is 4:5
Explanation:
So, for the case of men, the power would be = 20 watt
And in case of the boy, power would be = 25 watt
Hence, the power delivered by boys more than men and the ratio of powers of man to boy is
To know more:
A boy does 400 j of a work in 20 s and then he does 100 j of a work in 2s find the ratio of the power delivered by the boy in two cases
