You are taking sediment samples from a very deep part of the ocean. The surface waters at this location consistently have large blooms of coccolithophores. Do you expect to find the coccolith shells in your samples? Why or why not?

The satellite with more mass will definitely have a higher speed. The correct option among all the options that are given in the question is the first option. Although the satellite having more mass should have a larger mass difference to have a noticeable speed change. Otherwise it would be hard to detect the speed change. Also we know that
orbit speed = proportional to square root[(Mass of Earth + Mass of Satellite)/orbit radius]. This explains the answer.
