Chapter 17, Problem 55EAP

The Speed of Supernova Debris. In the year 2001, debris moving outward from Supernova 1987A was seen hitting a preexisting ring of gas at a distance of 0.7 light-year around the star that exploded. Calculate the speed of that debris. How does the speed you find compare with the speed of light?

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?
Make a plot of the acceleration of a ball that is thrown upward at 20 m/s subject to gravitation alone (no drag). Assume upward is the +y direction (and downward negative y).
