A moving particle encounters an external electric field that decreases its kinetic energy from 8650 eV to 6910 eV as the particle moves from position A to position B. The electric potential at A is -56.5 V, and the electric potential at B is +28.1 V. Determine the charge of the particle.
What is the magnitude of the force on an electron that is in the region between the plates at a point accurately 2.52 mm from the positive plate
A 4.22 box sits at rest at the bottom of a ramp that is 7.74 long and that is inclined at 40.0 above the horizontal. The coefficient of kinetic friction is 0.40, and the coefficient of static friction is 0.50.
What would be the equilibrium temperature when a 253-g block of copper at 281^circ C is placed in a 137g aluminium calorimeter cup containing 817-g of water at 14.5^circ C.
The jet accelerates uniformly, and during that time, the pendulum oscillates about the equilibrium position shown by the solid line, with D = 0.370 m. find the magnitude of the plane's acceleration.
Let the x axis be parallel to the ground, +y direction be vertically upward, and take as an origin the point on the ground directly below the top of the ramp.
What is the coefficient of static between crate and incline
