Q. A copper strip (n = 8.47 1022 electrons per cubic centimeter) 2 cm wide and 0.07 cm thick is used to measure the magnitudes of unknown magnetic fields that are perpendicular to the strip. Find the magnitude of B for the following Hall voltages when I = 21 A.
Q. While waiting to cross the street, an ambulance passes by you with a speed of 25 m/s. The siren has a frequency of 900 Hz. What is the drop in frequency as the ambulance passes you? (v=343 m/s)

An ocean liner leaves New York City and travels 21° north of east for 134km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the directions.
A player uses a hockey stick to increase the speed of a 0.200 kg hockey puck by 6m/s in 2 seconds. how much force was exerted on puck? how much on the stick.
A piece of balsa wood with density 0.50g/cm^3 is released under water. What is the initial acceleration?? Repeat for a piece of maple with density 0.760 g/cm^3? Repeat for a ping-pong ball with the average density of 0.127 g/cm^3.
A 65Kg ice skater pushes off his partner and accelerates backwards at 1.3m/s^2. If the partner accelerates in the opposite direction at 2.0m/s^2, what is mass of the other skater.
Assume you are the fish. You get up every morning and weigh yourself (in water), and find you weigh 0.42 N. You, being a boxfish, are a box measuring 4.164 cm per side. You see a poor, hungry fisherman, and decide to be his dinner. You hook yourself,..
