Question

This phenomenon and ram pressure are the two main drivers of the destruction of dwarf satellite galaxies via "stripping." Quiescent supermassive black holes can become transiently observable when a star’s orbit is "disrupted" by this phenomenon. This phenomenon, whose magnitude is proportional to the negative-third power of (*) distance, causes Io's volcanism and the spaghetti·fication (10[1])of objects near black holes. The same half of a satellite always faces the body it orbits due to this phenomenon's namesake (10[1])"locking." "Spring" and "neap" periods named for this force occur when the Sun's gravitational pull reinforces or opposes the Moon's. For 10 points, name this force that drives oscillations in sea level. ■END■
