Polarizing filters in the fifth lab (the ters and measured the resulting intensity. initially vertically polarized light, with an intensity io, is sent through two (ideal) polarizing sheets, whose transmission axes are 45° and 90° to the vertical. will the intensity of the light be greater or less than if with the polarizers), you shined light through polarizhng there were only polarizer at 90° to the yertical? explain. note that malus law one says i2= i cos2 e

Which statement best explains why an object weight less on mercury than it does on earth

Apulley system is used to lift a 2,000 newton engine up a distance of 3 meters. the operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor. to lift the engine 3 meters, the operator must pull a total of 30 meters of chain through the pulley system. what is the value of di?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
