A "swing" ride at a carnival consists of chairs that are swung in a circle by 19.3 m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 263 kg.
(a) Determine the tension in the cable attached to the chair.
(b) Find the speed of the chair.
Find out the critical angle theta_ce for e-waves in calcite. The index of refraction for light with electric field parallel to the optical axis (called extraordinary waves or e-waves) is 1.4864. The index of refraction for light with electric fiel..
