An object’s mass is not determined by gravity, however weight is. With this information, you can figure out that Mars has less gravity acting on the object.
Not sure if this is right but I think it’s TRUE sorry if it’s wrong....
Take a right triangle and apply pythagorean theorem where the displacement is the hypotenuse:
We get 36.25m
C) The object would be WHITE.
We call "white light" to the sunlight, but referred to the visible part of spectrum. If the object reflects all the light, it appears as a white object.
