Work = Force times distance
from your "answers" the one that bests fits this equation is weight since this is a type of force
The object velocity is 282.4
Answer:
C ) 1.53
Explanation:
The critical angle of a material is given by the formula

where
c is the critical angle
n is the refractive index
This formula is valid if the second medium is air (which is the case of the problem).
In this problem, we know the critical angle:

Therefore we can rearrange the equation to find the refractive index:

Answer:
B. has the greatest mass
Explanation:
mass & distance affect pull
grativy affects speed & shape of orbit of the planet
