Answer:
It is also called law of Malus,the law states that the intensity of a beam of plane-polarized light after passing through a rotatable polarizer varies as square of the cosine of the angle through which the polarizer is rotated from the position that gives maximum intensity expand.
Before u can know it u have to understand it, so go through it over and over again and u will get it.
Horizontal forehead wrinkles are caused by contraction of the frontalis muscles. The frontalis muscles are two large fanlike muscles that extend from the eyebrow region to the top of the forehead. I think this is the answer
Answer:
It would be hard to make a model that shows the real sizes and distances between planets ( B )
Explanation:
Yuri building a model of the solar system will face the difficult of replicating the correct distances between the planets and the real sizes of the planets, because in model building the key factors of the Model must be represented properly.
The size of the planets and the distance between the planets are key factors when trying to model the solar system. but the distance between the planets depends on the position of the planets on their orbits which means the distances are not constant ( fixed ) hence that would be the limitation of his model.
Explanation:
Orbital period = 2 x 10⁶s
Total radius = 2.5 x 10¹²m
Unknown:
Tangential speed of the satellite = ?
Solution:
The tangential speed simply expresses the rate at which the distance moves around its orbit with time.
Since the orbit is taken to be circular;
Tangential speed = 
r is the radius
t is the time or orbital radius
Tangential speed = ![\frac{2 x 3.14 x 2.5 x 10¹²}{2 x10[tex]^{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20x%203.14%20x%202.5%20x%2010%C2%B9%C2%B2%7D%7B2%20x10%5Btex%5D%5E%7B6%7D)

Tangential speed = 7.85 x 10⁶m/s
