A 20 N object is placed on a surface and starts to slide. What is the MOST likely reason the object begins to move?
ra1l [238]

Answer:

c.

Explanation:

If the object starts to slide it must be on a slope.

There are 2 forces acting on the object - gravity and the friction between the object and the surface.

If sliding starts then the forces must be unbalanced.

The force of gravity is greater than the friction.

How would the volume of helium in a balloon be affected if the balloon was placed in a room where air temperature is lower?
Alexus [3.1K]

Answer:

The volume will decrease.

Explanation:

According to Charles' Law, the volume of a gas is directly proportional to its temperature.

V = kT

Thus, if T decreases, V decreases.
