Question

A diver immersed in the sea (nagua mar = 1.34), looks up at an angle of 67º with the horizontal. Through the hollow of a life preserver floating on the surface, he sees the tip of a fireplace on a nearby island. The height of said chimney is known to be 78 m, how far is the lifeguard from the base of the chimney?
a) 47.9 m
b) 88.3 m
c) 105 m
d) 127 m

You are working at your university swimming center. The athletic department decides that it would like to install a flag pole of height 10.0 m at the south end of one of the outdoor pools, which lies along a north-south axis. The pool is 3.09 m deep and the flag pole is to be installed 4.35 m from the south edge of the pool, midway along the length of the south edge. (a) Your supervisor knows of your expertise in physics and asks you to determine the distance (in m) of the shadow of the tip of the flag pole on the bottom of the pool from the south wall of the pool on a summer day when the Sun appears directly south and at an angle of 65.0° above the horizon. m

The speed of light changes when it goes from ethyl alcohol (nea = 1.31) to carbon tetra- chloride (nct = 1.641). What is the ratio vct of the speeds?
For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 55.0 km due east and have it detected by a light sensor that is 123 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. (b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.004°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. m
