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 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 and exceeds a body’s (10[1])internal gravitational binding beyond the Roche (“rohsh”) limit. Satellites whose rotational period equals their orbital period exhibit a “locking” named for this phenomenon. For 10 points, name this phenomenon that causes sea levels to oscillate due to the position of the moon. ■END■
