water 2.25 x 108 m/s
glass 2 x 108 m/s
air 3 x 108 m/s
Light moves from air into a new material. The greatest refraction would occur when light passes through which material?
A) air
B) glass
C) water
D) It would refract the same amount in each material.
Answer: I think the answer is B glass.
Explanation: Because Glass is light.
Answer:
684J
Explanation:
So basically the formula for gravitational potential energy is Mass X Gravity X height. That is G.p.e = mgh
We don't have the mass but since we have the height, we multiply directly with the height since the quantity of weight is already given.
so G.p.e = 360 X 1.9 = 684J
Note that; The answer is in joules because g.p.e is work done.

Explanation:
Answer:
23.5 N
Explanation:
Just wanted to clarify something about the verified answer: Our only given measurement—the mass of the object—has 3 significant digits, so we can only include 3 significant digits in our answer.
23.52 N is NOT the correct answer. Your answer should only have 3 significant digits.
I just did the quiz where this problem came from, so I know that 23.5 N is the correct answer.
