Round 10: Tossup 7

Gamma ray bursts such as Swift J1644+57 occasionally turn out to be “disruption events” named for this phenomenon (10[1])that occur near supermassive black holes. (10[1])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 Antenna galaxies. This phenomenon is primarily responsible for hypothetical “eyeball planets.” (10[1])The strength of this phenomenon has an inverse cubic dependence on distance (-5[1])and exceeds a body’s internal gravitational (10[1])binding beyond the Roche (“rohsh”) limit. Satellites 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 (10[1])to oscillate due to the position of the moon. ■END■
