Answer:
Light
Explanation:
The way a concave mirror works is that since it's concave, the light bounces off of each other. a convex mirror, it curved the opposite, and the mirror has no way to bounce off of itself.
I don't know for sure but i think that it is because the force him pushing her pushed him back as well
Hope i helped
When you are finding work, the easiest way is to use the formula.
W = F*D
Where F is the force and D is the distance. Simply take the constant force of 209N and multiply it by the distance of 10m. Which will give you 2090J
C is the answer to the question
Distance = 2AU / tan1.0
If you mean 1.0 is in degrees, then Distance = 114.58 AU
