Textbook Question
Chapter 4, Problem 41POS
The Age of Earth. Some people still question whether we have a reasonable knowledge of the age of Earth or the ability to date events in Earth’s history. Based on what you have learned about both relative and absolute ages on the geological time scale, do you think it is reasonable for scientists to be confident of ages found by radiometric dating? Is there any scientific reason to doubt the reliability of our chronology of Earth? Explain.

Defination of voltage
At point A, 3.20 m from a small source of sound that is emitting uniformly in all directions, the intensity level is 58.0 dB. What is the intensity of the sound at A? How far from the source must you go so that the intensity is one-fourth of what it was at A? How far must you go so that the sound level is one-fourth of what it was at A?
