In a Hall effect experiment, a current of 2.5 Amp sent lengthwise through a conductor 0.9 centimeter wide, 4.5 centimeter long, and 9 μm thick produces transverse (across the width) Hall voltage of 8.6 μV when a magnetic field of 1.3 T is passed perpendicularly through the thickness of the conductor.
From these data, determine the drift velocity of the charge carriers.
Evaluate the number density of charge carriers. (m-3)

After reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 44.0. He finally comes to rest 22.0 below the level of the bridge. Illustrate what is the spring stiffness constant?
A fisherman yanks a fish vertically out of the water with an acceleration of 2.5m/s2 using very light fishing line that has a breaking strength of 22 N. Explain what can you say about the mass of the fish
A pair of slits, separated by 0.150 mm, is illuminated by light having a wavelength of ? = 631 nm. What is the path difference d for the two slits at the location y
You're driving down the highway late one night at 18 - {rm m}/{rm s} when a deer steps onto the road 45 -{rm m} in front of you. Your reaction time before stepping on the brakes is 0.50- {rm s}, and the maximum deceleration of your car is 11 {rm m..
