Answer:
The main effect of radiofrequency electromagnetic fields is heating of body tissues.
Explanation:
Image result for How do electromagnetic waves affect you?
At low frequencies, external electric and magnetic fields induce small circulating currents within the body. ... The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health.
Answer:
117.7 N
Explanation:
F = ma
= 12 kg * 9.81 m/s^2 = 117.7 N ( on Earth)
Based on the sped of the waves and the tension as well as the needed wave speed, the required tension is 13.5 N.
<h3>What is the required tension?</h3>
Given the initial tension and speed, the tension that is required can be found by the formula:
= Initial tension x (Required speed / Initial speed)²
Solving gives:
= 6 x (30 / 20)²
= 6 x 9/4
= 13.5 N
In conclusion, the tension required is 13.5N.

The answer is; Near the magnetic poles of Saturn
Auroras that are solar-generated occur when charged particles from the sun interact with the magnetosphere. The charged particles then interact iht the molecules in the atmospheres as they run through the planet’s magnetic field. Saturn's auroras are hydrogen based and can't be viewed in the visible light spectrum. Saturn also has other patched of auroras other than in its poles and these are not solar generated.
