Charge is distributed uniformly throughout the volume of an infinitely long cylinder of radius R = 4.00×10^-2 m. The charge density is 5.00×10^-2 C/ m^3. What is the electric field at r
Discuss the criterion one would use to determine how the charges are distributed on the inner and outer surface of the shells. What is the charge on the outer surface of the outer shell?
The wavelength of a light wave is 700nm in air; this light appears red. If this wave enters a pool of water, its wavelength becomes lamda-air/n= 530nm. If you were swimming underwater, the light wou

A mine car (mass = 474 kg) rolls at a speed of 0.368 m/s on a horizontal track, as the drawing shows. A 103-kg chunk of coal has a speed of 0.851 m/s when it leaves the chute. Determine the velocity
Two balls 14 cm in diameter are placed 200 m apart on a frictionless horizontal plane at 50º N (on the rotating Earth). If the balls are suddenly propelled directly at each other with equal (co
Johnny is running home from school to watch his favorite soap opera, "As the Stomach Turns". He runs 6 blocks east to a convenience store for some Redbull and chips, then 8 blocks north to his home.
A boat has a mass of 6020 kg. Its engines generate a drive force of 3350 N due west, while the wind exerts a force of 630 N due east and the water exerts a resistive force of 1100 N due east. Take w
A singly charged ion of unknown mass moves in a circle of radius 14.5 cm in a magnetic field of 1.40 T. The ion was accelerated through a potential difference of 7.49 kV before it entered the magne
