Which of the following statements is true?

1) on a level surface, normal force equals weight.

2) the more inertia an object has, the more easily it will change its motion.

3) the more massive an object, the more quickly it will accelerate.

4) action-at-a-distance forces require physical contact between objects.

B) The more inertia an object has, the more easily it will change its motion.

i think the answer is a, hope this is right, that would be my best guess.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
