Question

Chapter 18, Problem 1OQ

To determine

The conductor with the least resistance.

Expert Solution & Answer

Answer to Problem 1OQ

Solution: The conductor (b) gives the greatest resistance while the conductor (c) gives the least resistance.

Explanation of Solution

The resistance of a cylindrical conductor is given by:

R = R=ρlA , where ρ is resistivity, l is the length and A is the cross-sectional area.

As we can see, resistance is directly proportional to length and inversely proportional to area (or diameter).

Among the four conductors given, (b) has the greatest length and the least diameter, so it would have the greatest resistance.

Conductor (c) has the least length and the greatest diameter, so it would offer the least resistance.

Conclusion: Thus, the required answer is determined.

Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.
