Answer:
Explanation:
What a lot of words to solve such a simple problem! The perpendicular force is the one that is pushing straight down on the plane. There is no side to side movement here or friction acting on this dimension at all. Perpendicular force is the same as the weight of the block. That's it! Perpendicular force is also normal force which is the same thing as weight:
w = mg so
w = (4.04)(9.8) and
w = 4.0 × 10¹ N
The option which is not part of the kinetic molecular theory is that B. there is very little empty space in a gas.
As a matter of fact, gas particles are very tiny and they exist in mostly empty spaces.
