I think the answer would be d. polarized. "<span>Polarized </span>light waves<span> are </span>light waves<span> in which the </span>vibrations<span> occur in a </span>single<span> plane. The process of transforming unpolarized </span>light<span> into polarized </span>light<span> is </span>known<span> as polarization."</span>
These answers aren´t valid .
The correct answer will be:
Planetary system.
Answer:
1 st question: Control variable
2nd question: random variable
3rd question: if the two objects are dropped from the same height they will hit the ground at the same time
Answer:
it depends on temperature^^
Explanation:
hope this helped^^
Kinetic energy , KE= [1/2]m*v^2
m = 10 kg
v=20m/s
KE = [1/][(10kg)(20m/s)^2 = [1/2](10kg)(400m^2/s^2) = 2000 joule
Answer: 2000 joule
