Consult multiple-concept example 5 to review the concepts on which this problem depends. a light bulb emits light uniformly in all directions. the average emitted power is 150.0 w. at a distance of 5.00 m from the bulb, determine (a) the average intensity of the light, (b) the rms value of the electric field, and (c) the peak value of the electric field.

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?

An object is kept at 45 m high and how much time will it take to reach the ground
