The nucleus of an atom has all of the following characteristics except that it

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

The radius of an atom is closest in size to a

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
