Hope that helps!

Good luck :)

The correct answer is option c.

Explanation:

Work is defined as product of the force applied on object and displacement of the object.the direction of the force and displacement of the object are same in direction.It is measures is  Joules (J).

Joules(J)= Newton(N) × meter(m)

W = Work done in Joules

F = force applied in Newtons.

d = displace of the object due to applied force in miters

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

d

explanation:

v=uf/(u-f)
