Will give ! need answer right !
which of the following statements is true?

on a level surface, applied force equals weight.
a newton is equal to 9.8 m/s^2.
normal forces occur at perpendicular angles to the surface between two objects.
action-at-a-distance forces require physical contact between objects.

Normal forces occur at perpendicular angles to the surface between two objects.

Option B

The unit of force comes from its mathematical equation which says force is equal to the product of mass and acceleration. So, the unit of force becomes kg m/s². And this is the SI unit of force, which is also called newton. So 1 newton = 1 kgm/s².

Action at a distance forces are actually the non contact forces which can even work on a body even when the bodies aren't in contact with each other. The examples include gravitational force, magnetic and electric forces etc. So they don't need a physical contact between the two bodies.

But, normal forces are defined as the force that's acting directly on the axis of two bodies i.e perpendicularly to a surface or the part of a surface the body is resting. So, they have full impact on the touching surface.

a. they are both space stations

happy to

pls mark as brainliest.

the answer is a for sure mark brainliest i had got this right on usatestprep
