Atypical tornado can be envisioned as a cylinder of height 640 m, with a diameter of about 230 m (note: the visible funnel cloud is usually somewhat less than the actual diameter). the rotation in the tornado is approximately a `solid body rotation', meaning that it rotates very much like a solid cylinder would, even though air is a gas. if the outer edge of the cylinder has a speed of 51 m/s, and the air has a density of 0.97 kg/m3, determine the kinetic energy contained by the tornado.

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.
