match each force abbreviation to the correct description.

Answer:

Fp- force exerted by a push or pull

Fn- support force at a right angle to a surface

Fg also known as an object's weight

Ff- force that comes from a resistance to motion

Explanation:

Correct on EDGE 2020

The force abbreviation to the correct description is describe below;

Fp- force exerted by a push or pull.

Fn- support force at a right angle to a surface.

Fg- also known as an object's weight.

Ff- force that comes from a resistance to motion.

A force is an influence that can cause an object's motion to change. A force can cause a mass object to change its velocity, or accelerate. Intuitively, force can be described as a push or a pull. A force is a vector quantity because it has both magnitude and direction.

The term "force" has a specific meaning in science. At this level, it is perfectly acceptable to refer to a force as a push or a pull. A force is not something that an object possesses or possesses. Another object applies a force to another. The concept of a force is not restricted to living or non-living things.

Thus, Fp- force exerted by a push or pull.

Why is rain likely when warm, moisture-laden air meets cold air? A) The lighter warm air will rise and cool down, causing condensation and rain. B) The cold air moves faster and pushes the warm air away, causing condensation and rain. Eliminate C) The moisture in the warm air condenses on contact with the cold air, causing rain to fall. D) The cold air mixes with the warm air, reducing its temperature causing moisture to condense.

Heather is investigating the properties of light and how it travels. She places a glass on the windowsill and waits for the sun to shine on the glass and observes what happens. Next, she places a piece of cardboard in front of the glass. Which statement describes the results of her observations?

A Since glass is translucent, most of the light energy was reflected from the glass.
B When the cardboard was placed in front of it, the cardboard absorbed some of the light energy.
C The light from the sun was able to travel through the glass. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
D The glass absorbed the light and converted the light energy into heat energy. When the cardboard was placed in front of the glass, the heat was transferred from the glass to the cardboard.
When the sun hit the glass, the light energy was absorbed. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
