Answer:
Yeah
Explanation:
I mean, how about gravity for example! When you draw a free-body diagram, you will almost always have to include gravity. How about normal force, or static friction? There are defintely forces at hand.
I have the same exact question
The potential energy is directly proportional to the height.
If you double the height you double the potential energy.
Answer:
You could use Malus's Law.
Malus's Law tells us that if you have a polarized wave (of intensity
I
0 0
) passing through a polarizer the emerging intensity (
Y
OR
) will be proportional to the square cosine of the angle between the polarization direction of the incoming wave and the axis of the polarizer.
