A crate is pushed 1.50m horizontally with a force of 2.40N under an opposing force of friction of 0.600N. What is the NET work done on the crate?

2.7 J

Explanation:

From the question,

The Net work done by the crate = Work done by the crate in moving if through a distance- work done against friction.

W = Fd-F'd Equation 1

Where F = force applied to the crate, d = distance moved by the crate, F' = force of friction

Given: F = 2.4 N, F' = 0.6 N, d = 1.5 m

Substitute these values into equation 1

W = 2.4(1.5)-0.6(1.5)

W = 3.6-0.9

W = 2.7 J

multiply 2kg by latent heat of vap

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
