A charge q is at the origin A charge 2q is at x 8.90 m on the x axis a For what finite value of x is the electric field zero 21.4865 Correct Your answer is correct seenKey 21.5 m b For what finite values of x is the electric potential zero Note Assume a reference level of potential V 0 at r Smallest value of x

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
