Packet 4: Tossup 6

A solid object will be destroyed by this phenomenon as it crosses a distance threshold of 1.26 times (15[1])radius (15[1])times the cube (-5[1])root of a ratio (15[1])of two densities. This phenomenon causes the appearance (15[1])of namesake “tails” (15[1])in colliding galaxies. (-5[1])This phenomenon, (-5[1])whose strength is inversely (15[1])proportional to distance cubed, (-5[1])causes internal (-5[1])friction that heats (15[2])up (15[1])Io’s (15[1])volcanoes. (15[4])Objects are (15[1])disintegrated by this phenomenon (-5[1])within the (*) Roche (-5[1])limit. (10[1]-5[2])This phenomenon causes the (10[1])Moon’s (10[1])rotational (10[1])and orbital (10[1])periods to synchronize (10[1])in its namesake (10[2])“locking.” (10[3])This force (10[1])is caused (10[1])by gradients in the strength (-5[1])of gravity. (10[3])For 10 points, (10[1])what force drives a periodic rising and falling of sea level on Earth? (10[2])■END■ (10[4]0[1])
