Three charged particles are arranged into a triangle. The charge on the particle located (4.0cm, 3.0cm) is 5nC. The charge on the particle at the origin is -3nC, and the change on the particle located at (4.0cm, 0cm) is +6nC. Determine the magnitude and direction of the force on the 5nC particle.
A stationary radar operator determines that a ship is 11.00 km south of him. An hour later the same ship is 24.0 km southeast. If the ship moved at constant speed and always in the same direction, what was its velocity for the duration of this tim..
what is the magnitude of the charge on each sphere. A car crashes into a wall at 45 m/s and is brought to rest in 0.1 s. compute the average force exerted on a 80 kg test dummy by the seat belt.
What should the charge (sign and magnitude) of a particle of mass 1.47g be for it to remain stationary when placed in a downward-directed electric field of magnitude 660 N/C.
How high up a frictionless incline could mass climb? How far could the mass skid on a level table with a static mu of 0.70 and a kinetic mu of 0.50.
Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.40 s before coming to rest. How numerous revolutions did the centrifuge complete after being turned off.
What minimum constant acceleration does this need if the aircraft is to be airborne after a takeoff run of 250 m.
