Answer 1

Answer:

B )a boy pushing a cart on a level plane

Explanation:

since pushing a cart needs muscular force

Answer 2

B. a boy pushing a cart on a level plane.

Explanation:

The gravitational force is a force that attracts any object with mass. Gravitational force is the force exerted by Earth on all objects on its surface and above. Objects will be attracted towards the Earth's surface as a result of the gravitational pull. A boy pushing a cart means both the boy and the cart are already on the ground. So the boy uses his muscular energy to push the cart along the level pane. So it is not an example of gravity, while all the other options are example of gravity in play.

Option B is the answer.
