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.
What is force ?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.

How does the amount of water in a glass affect the pitch of the sound it produces?
Answer:
the more water the higher the pitch the less water the lower it is
Answer:
The glass with the most water has the lowest pitch. The glass with the least amount of water has the highest pitch.
Explanation:Tapping the glasses causes the air to vibrate. When the air column is shorter, the air vibrates faster and the pitch is higher.

How does the atmosphere make Earth warmer?
Answer:
Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.
