A "step-down" transformer is used to reduce the voltage from 11060 V to 240 V before it is connected to houses in a neighborhood. If the transformer has 50 turns on the secondary, how many turns does it have on the primary

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?

Explain what happens at the saturation point when adding salt to water at room temperature.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
