An electron with a speed of 1.1 × 107 m/s moves horizontally into a region where a constant vertical force of 5.6 × 10-16 N acts on it. The mass of the electron is 9.11 × 10-31 kg. Determine the vertical distance the electron is deflected during the time it has moved 39 mm horizontally.
A copper wire has diameter 0.140mm and length 11.0cm . It's in a horizontal plane and carries a current of 2.50A, Find the magnitude of the magnetic field needed to suspend the wire against gravity.
A herd of wild horses races across the flat, open plains of the Great Basin in central Nevada. If the horses are running at 12.1 m/s at a compass heading of 286 degrees, illustrate what is the northward component of their velocity?
During the collision with the ground, he comes to rest in a time of .101 s. The average force exerted on him by the ground is +18000 N, where the upward direction is taken to be the positive direction. Elucidate from what height did the student f..
a model rocket is shot straight up. shortly running out of fuel, the upward thrust on the rocket is 2 N, calculate the mass of the rocket
You are rotating a 2.0kg rock in a vertical circle,using a very light string. Find the speeds of the rock at the highest and lowest position
A recantangular block of wood floats in a calm lake. Show, if friction is ignored, determine an equation for the force constant
Suppose you throw a 0.048-kg ball with a speed of 10.7 m/s and at an angle of 32.1° above the horizontal from a building 11.5 m high. What will be its kinetic energy when it hits the ground
Consider a cylindrical shell of inner radius a = 1.10 cm, outer radius 2a, and length L = 2.05 m. This cylinder has a total charge Q = 138 nC. Find the potential difference between the inner and outer surfaces of the cylindrical shell
