Atugboat is pushing a barge into a harbor. the barge is exerting a force of 3000 n against the tugboat. which force would most likely allow the tugboat to move the barge into the harbor?
a) 4500 n
b) 2500 n
c) 2500 n
d) 4500 n

a) 4500N d)4500N

Explanation:

Newton's first law states that a body tends to remain at rest unless a force greater than its resistance force acts on it.

In this case the barge has a resistance force of 3000N which means that to move it requires a greater force, so we conclude that the answer is

a) 4500N d)4500N

A -4500

Explanation:

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
