explain how a roller coaster functions using gravity and momentum. Why does it not need an engine or a motor to speed it up and slow it down?

Answers

Answer 1

Answer:

A roller coaster does not have an engine to generate energy. This builds up a supply of potential energy that will be used to go down the hill as the train is pulled by gravity. Then all of that stored energy is released as kinetic energy which is what will get the train to go up the next hill.

how does a supercharger work?

Answers

Answer:

Supercharger works through a pair of rotors that blow air at a high speed into the intake port. As the port then contains a greater quantity of air, it becomes compressed. This enables a higher quantity of fuel to be injected into the combustion chamber, thus generating higher power.

What do the cells and tissues of the endocrine system release to help maintain homeostasis in the body?

Answers

glands. hope this helps!!

The cells and tissue of the endocrine system release hormones to help maintain homeostasis in the body.

What is the endocrine system?

The complex network of glands and organs that makes up the endocrine system secretes hormones—chemical messengers—directly into the bloodstream. The hormones then travel through the bloodstream to their target cells, where they must act.

The hormone-producing glands may or may not be nearby the target cells. The nervous system and endocrine system collaborate to start or stop movement and physiological function.

A body's homeostasis is maintained by a negative feedback mechanism (activation of one component does not activate the other). All body systems must be in a condition of balance for the body to survive and work properly.

Therefore, to support the body's homeostasis, the cells, and tissues of the endocrine system release hormones.

Are all types of respirators the same?

Answers

No

What are the different classes of respirators?
The two main types are air-purifying respirators (APRs) and supplied-air respirators (SARs).

Air-purifying respirators can remove contaminants in the air that you breathe by filtering out particulates (e.g., dusts, metal fumes, mists, etc.). Other APRs purify air by adsorbing gases or vapours on a sorbent (adsorbing material) in a cartridge or canister. They are tight-fitting and are available in several forms:

mouth bit respirator (fits in the mouth and comes with a nose clip to hold nostrils closed - for escape purposes only)
quarter-mask (covering the nose and mouth)
half-face mask (covering the face from the nose to below the chin)
full facepiece (covering the face from above the eyes to below the chin)
