Want to know:
Ohmmeters are also a useful meter for measuring resistance. Which of the following statements about the Ohmmeter is true? (A) The Ohmmeter should not be hooked up to an active circuit, or it risks false readings and damage. (B) The Ohmmeter relies upon an outside battery charge, and can adapt to different voltages. (C) The Ohmmeter measures the active circuit's voltage and current, and will give the equivalent resistance. (D) All of the above statements are true.

- Suppose that a pane of crown glass, with a refractive index of 1.52, is immersed in water, which has a refractive index of 1.33. A ray of light traveling in the water strikes the glass at 45° relative to the normal and travels through the pane. What angle, relative to the normal, will the ray of light subtend when it leaves the pane and reenters the water? 38° 54° 32° 45° No angle at all! The premise is wrong. The light will never enter the glass. It will be reflected when it strikes the glass surface.
- t or fthe absorption coefficient varies with the intensity of the incident wave
- Einstein's theory of special relativity contains some very strange ideas such as time dilation (moving clocks run slow), length contraction (moving lengths are shorter), and lack of absolute simultaneity. What is the basis of these ideas?
