-B because metal hardly breaks but non metal items such as glass or plastic does!
Because static electricity build up in our homes because we have the heaters on which suck moisture out of the air.
Answer:
Answer:B
Explanation:
Because it all stayed consistant
The centrifugal force C = mv^2/r = kq^2/r^2 = P centripetal force. m is the electron mass, q are the proton and electron charges (opposites), and r is the Bohr radius.
Thus 1/2 mv^2/r = 1/2 kq^2/r^2 and KE = 1/2 mv^2 = 1/2 kq^2/r = 1/2 PE
Therefore KE/PE = 1/2, no matter what state the electron is in.
