Due to the moon's gravitational force and inertias counterbalance.
Answer:
velocity. height. weight. possition. place. energy. force.
Explanation: 50/50 % chance they are wrong and write.
Let's use the mirror equation to solve the problem:

where f is the focal length of the mirror,

the distance of the object from the mirror, and

the distance of the image from the mirror.
For a concave mirror, for the sign convention f is considered to be positive. So we can solve the equation for

by using the numbers given in the text of the problem:



Where the negative sign means that the image is virtual, so it is located behind the mirror, at 8.6 cm from the center of the mirror.
I believe if it were heavier with more mass, then the sun would pull it in and there would be no mercury. It might also be hotter.
