Question

A man can use a snowblower to move snow in 5 minutes. If he moves it with a shovel, will take 20 minutes. He will use more power with which process?

Answer 1

Using a snowblower requires more power compared to using a shovel.

Step-by-step explanation:

The man uses more power when moving snow with a snowblower compared to using a shovel. Power is the rate at which work is done or energy is transferred. It is calculated by dividing the work done or energy transferred by the time taken.

Using a snowblower takes the man 5 minutes to move the snow, while using a shovel takes him 20 minutes. Since power is inversely proportional to time, the longer it takes to do the work, the lower the power. Therefore, using a shovel requires less power compared to a snowblower.
