Chapter 31: Q. 56 (page 903)

Unpolarized light of intensity I0is incident on three polarizing filters. The axis of the first is vertical, that of the second is 45°from vertical, and that of the third is horizontal. What light intensity emerges from the third filter?

Short Answer

Expert verified

Light intensity emerges from the third filter is0.1175Io2.

Step by step solution

01

Formula and Calculation for angle

Given info:

First Angle is θ1=45°.

Second angle is θ2=90°.

Intensity is,

I1=Io2cos2θ

02

Calculation for intensity

Intensity for third filter is,

I3=Io2cosθ

I3=0.235Io20.5

I3=0.1175Io2

A 5.0cmdiameter parallel-plate capacitor has a 0.50mmgap. What is the displacement current in the capacitor if the potential difference across the capacitor is increasing at 500,000V/s?

Large quantities of dust should have been left behind after the creation of the solar system. Larger dust particles, comparable in size to soot and sand grains, are common. They create shooting stars when they collide with the earth's atmosphere. But very small dust particles are conspicuously absent. Astronomers believe that the very small dust particles have been blown out of the solar system by the sun. By comparing the forces on dust particles, determine the diameter of the smallest dust particles that can remain in the solar system over long periods of time. Assume that the dust particles are spherical, black, and have a density of 2000kg/m3. The sun emits electromagnetic radiation with power 3.9×1026W.

An 80kgastronaut has gone outside his space capsule to do some repair work. Unfortunately, he forgot to lock his safety tether in place, and he has drifted 5.0maway from the capsule. Fortunately, he has a 1000Wportable laser with fresh batteries that will operate it for 1.0h. His only chance is to accelerate himself toward the space capsule by firing the laser in the opposite direction. He has a role="math" localid="1649937737036" 10-h supply of oxygen. How long will it take him to reach safety?
