1. How does a cell phone use radiation to function?
Cell phones use radiation to carry messages and calls and the radiation transmission
occurs between your phone and the cell towers and is at maximum power when a
phone call is initiated and the handshake
1. A whistle you use to call your hunting dog has a frequency of 21 kHz, but your dog is ignoring
it. You suspect the whistle may not be working, but you can't hear sounds above 20 kHz. To
test it, you ask a friend to blow the whistle and hop on his moped

1. Do waves transport the energy of disturbances? Explain.
Yes, because waves respond to disturbances by radiating energy outwards from the
source of the disturbance.

1. A gas occupies 0.60 m3 at a 5.0 atm. If the temperature of the gas remains the same and the
pressure decreases to 2.5 atm, what would be the new volume occupied by the gas?
P1 = 5.0 atm
V1 = 0.60 m3
P2 = 2.5 atm
V2 = ?
P1V1 = P2V2
V2 = P1V1/P2
V2 = (5.
1. The Washington Monument is 555 feet tall.
A. If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters?
1 m = 3.28 f
Monument = 555 f
Height in meters = f/m
H = 555f/3.28m
H = 169.207 m
H = 169.0 m
