Tossup

Gamma ray bursts such as Swift J1644+57 occasionally turn out to be “disruption events” named for this phenomenon that occur near supermassive black holes. The heating rate due to this process is proportional to a body’s second-order Love number. This phenomenon between interacting galaxies generates the “tails” in the Tadpole and (10[1])Antenna galaxies. This phenomenon is primarily responsible for hypothetical “eyeball planets.” The strength of this phenomenon has an inverse cubic dependence on distance and exceeds a body’s internal gravitational binding (10[1])beyond the Roche (“rohsh”) limit. (10[1])Satellites (-5[1])whose rotational period equals their orbital period exhibit a “locking” named for this phenomenon. (10[1])For 10 points, name this phenomenon that causes sea levels to oscillate due to the position of the moon. ■END■ (10[1])
