Black holes form overcomes the by nuclear reactions within a star.

a. gravity; energy
b. gravity; pressure
c. pressure; energy
d. energy; pressure

I'm pretty sure it's B) gravity;pressure because a black hole is caused when a star's gravity implodes on itself.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
