You are to make four straight-line moves over a flat desert floor, starting at the origin of an xy coordinate system and ending at the xy coordinates (−140 m, 30 m). The x component and y component of your moves are the following, respectively, in meters: (20 and 60), then ( b x and −70), then (−20 and c y ), then (−60 and −70). What are (a) component b x and (b) component c y ? What are (c) the magnitude and (d) the angle (relative to the positive direction of the x axis) of the overall displacement?

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?
