Answer :

(i) Mass of butterfly = 1 g = 1/1000


velocity= 0.5 m/s


Power = mg × velocity, g = 10 m s–2



(ii) Mass of squirrel = 250 g = 250/1000


velocity= 0.5 m/s


Power = mg × velocity, g = 10 m s–2



Hence, the power with which the squirrel is climbing is much higher than that of a butterfly flying.
