Chapter 6: Q4DQ (page 1519)

The gravitational force between two electrons is weaker than the electric force by the order of10-40 . Yet the gravitational interactions of matter were observed and analyzed long before electrical interactions were understood. Why?

Short Answer

Expert verified

Due to the gravitational pull of the massive earth, the gravitational interactions of matter were observed and analyzed long before electrical interactions were understood.

Step by step solution

01

Determine the reason why the given observations were made

There is no electrical interaction between the two electrons because most of the bodies are neutral. Thus,the gravitational force is the only force that survives. We observe gravitational force daily, but observation of an interaction between electrons on a microscopic level is complicated.

Therefore, due to the gravitational pull of the massive earth,the gravitational interactions of matter were observed and analyzed long before electrical interactions were understood.

In an experiment involving the photoelectric effect, if the intensity of the incident light (having frequency higher than the threshold frequency) is reduced by a factor of 10 without changing anything else, which (if any) of the following statements about this process will be true? (a) The number of photoelectrons will most likely be reduced by a factor of 10. (b) The maximum kinetic energy of the ejected photoelectrons will most likely be reduced by a factor of 10. (c) The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 10. (d) The maximum speed of the ejected photoelectrons will most likely be reduced by a factor of 110. (e) The time for the first photoelectron to be ejected will be increased by a factor of 10.

Analysis of the photon absorption spectrum of a diatomic molecule shows that the vibrational energy levels for small values of n are very nearly equally spaced but the levels for large n are not equally spaced. Discuss the reason for this observation. Do you expect the adjacent levels to move closer together or farther apart as n increases? Explain.

The wave functions for a particle in a box (see Fig. 40.12a) are zero at certain points. Does this mean that the particle can鈥檛 move past one of these points? Explain.

Figure 40.15a shows that the higher the energy of a bound state for a finite potential well, the more the wave function extends outside the well (into the intervals x鈫�0 and x鈫�L). Explain why this happens.

The speed of light relative to still water is 2.25脳108m/s .If the water is moving past us, the speed of light we measure depends on the speed of the water. Do these facts violate Einstein鈥檚 second postulate? Explain.
