If a person pulls a cart to the right at 5N of force and another person pulls to the left with a 15N of force? What is the net force and it what direction

The net force is 10 [N] acting to the left

Explanation:

To solve this type of problem we must make a sum of the forces acting on the cart, since the forces are vectors, we know that vectors can be added, In this way forces that go in the same direction are added and forces in opposite directions are subtracted.

FL = force to the left = - 15 [N]

FR = force to the right = 5 [N]

FT = Resultant force [N]

- 15 + 5 = FT

FT = - 10 [N]

The negative sign tells us that the force acts to the left.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
