how do infrared waves, uv waves,and microwaves affect us

Answers

Answer:

Here is your answer

Explanation:

Infrared radiation has a longer wavelength and lower frequency than visible light. Too much exposure can damage your eyes and skin. On a global scale, trapped infrared radiation contributes to global warming.

UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. Exposure to UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis. UV rays can also cause eye problems.

Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn.  But these types of injuries – burns and cataracts – can only be caused by exposure to large amounts of microwave radiation.

Describe the four major spheres that support life on Earth.
Explain how rays AB and AC form both a line and an angle.

Answers

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Two rays AB and AC having the same endpoint are opposite rays if they two rays are unequal but line AB is equal to line AC. Otherwise they are nonopposite. An angle is the union to two nonopposite rays AB and AC sharing the same endpoint. The angle is denoted by either angle BAC or angle CAB.

If you have a container with hydrogen atoms and oxygen atoms in it do you automatically have water?

Answers

Answer:

no

Explanation:

you have to have the right amount and the right situation for it to turn into water. for instance The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
