The experimenter from the video rotates on his stool, this time holding his empty hands in his lap. you stand on a desk above him and drop a long, heavy bean bag straight down so that it lands across his lap, in his hands. what happens? view available hint(s) the experimenter from the video rotates on his stool, this time holding his empty hands in his lap. you stand on a desk above him and drop a long, heavy bean bag straight down so that it lands across his lap, in his hands. what happens? he spins slower. it's not possible to predict what will happen. he continues spinning at the same speed. he spins faster.

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.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
