Electromagnetic waves are produced by light. They are made up of oscillating magnetic and electric fields. They include radio waves, microwaves,infrared waves, visible light, ultraviolet, x-rays and gamma rays. Electromagnetic waves carry energy. radio waves are used in communications to send signals from one place to another.Microwaves use high energy that increases the motion of molecules in your food. Infrared waves are used in things like night vision cameras or a tv remote. The human body has a temperature that produces radiation which can be picked up by an infrareds device.Ultraviolet light ( like from the sun) can cause sunburn and skin cancer . That.s why it’s important to wear sunscreen and sunglasses to protect our bodies and and our eyes. X-rays are very high energy and like ultraviolet rays can cause damage to the body. But x-rays used at the right amount can be safe on the tissues and organs in our bodies. Hope this helps !

When conducting a search to identify a text's credibility and reliability, you have to check the following characteristics:
- Sources: where the information is obtained and it is supposed to be true. It is said that you need at least three different sources that explain the same information for it to be validated.
- Is the article is current?: articles could change all the time, specially scientific ones because new discoveries can change what was discovered before, so it is important to check if the text you are reading is current or not, and if it is not, you need to check if something has changed during all those years.
<h3>Article's credibility</h3>
In this exercise, you have to present an article and describe the purpose of the source and if the article is current or not.

Answer:
5.90 ft/s^2
Explanation:
There are mixed units in this question....convert everything to miles or feet
and hr to s
28 mi / hr = 41.066 ft/s
Displacement = vo t + 1/2 at^2
599 = 41.066 (8.9) + 1/2 a (8.9^2)
solve for a = ~ 5.90 ft/s^2
the answer is 40.5 because you have to multiply the density and volume of the object to get the mass.
