HEL (This is for Astronomy i put physics cuz that’s the closest thing) Which of the following BEST describes the gravitational binding of galaxies?
A) They are arranged from smallest to largest.
B) There is no certain arrangement.
C) They are found in clumps called clusters or superclusters.
D) They often violently collide because of their absence of gravity.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
