Question

A man raises 10 bricks on the roof in 15 minutes. A

10 bick on the same roof in 30 minutes which or them does more work.​

Answer 1

The man raising 10 bricks in 15 minutes and the 10 bricks on the roof in 30 minutes do the same amount of work. Work is calculated as force multiplied by distance, and since the force applied is the same in both scenarios, the work done is also the same.

Step-by-step explanation:

In this question, we are comparing the work done by a man raising 10 bricks in 15 minutes to the work done by 10 bricks on the same roof in 30 minutes. To determine which one does more work, we need to calculate the work done by each. Work is equal to the force applied multiplied by the distance moved. Since the distance moved is the same for both scenarios (raising the bricks to the roof), we can compare the force applied. The force applied is the weight of the bricks, which is equal to the mass of the bricks multiplied by the acceleration due to gravity. Since both scenarios involve 10 bricks, the mass is the same in both cases. Therefore, the force applied in each scenario is the same.

Now, let's calculate the work done by each scenario. Work is equal to force multiplied by distance, so the work done by the man raising the bricks is equal to the force applied by the man (weight of the bricks) multiplied by the distance moved (raising the bricks to the roof). Similarly, the work done by 10 bricks on the roof is equal to the force applied by the bricks (weight of the bricks) multiplied by the distance moved (remaining on the roof). Since the force applied is the same in both scenarios, the work done is also the same.

Therefore, both the man raising 10 bricks in 15 minutes and the 10 bricks on the roof in 30 minutes do the same amount of work.

Answer 2

A man has more power than a boy

because a man rise 10 brick in the 15

minutes. and a boy rise 10 Brick on the

same route in 30 minutes .show a man

has more power than a boy .
