Q. The force an electric field of strength E (N/Coulombs) applies to a particle of charge Q coulombs is simply Q * E. If the charge is positive, the force is in the direction of the field.
a) How much force does a 150,000 N/C force exert on a deuteron (1 neutron and one proton)
b) How much KE will it gain if stays in this field for 2 m
How fast will it be going?
If the velocity of the car is increased to 50 km/ hour, what is its kinetic energy. if the velocity is improved to 75 km/ hour, what is its kinetic energy.
An object is oscilliating on a spring with a period of 4.60 s . At time t= 0.00 s the object has zero speed and is at x = 8.30 cm . What is the acceleration of the object at t= 2.50 s ?
What angle does water surface make with the horizontal
In the meantime, the velocity of airplane Q relative to the air is 250 m/s in the direction of N 20o W. What is the speed of airplane Q relative to the airplane P.
An event occurs at x′ =60m, t′ =8×10-8 sec in a frame S′ (with y′ =0, z′ = 0). The frame S′ has a speed of 3c/5 in the x direction with respect to frame S. The origins of S and S′ coincide at t = 0, t′ = 0. What are the spacetime coordinates of th..
Assume someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree.
Assume, instead, that the observer had been moving away from Earth with a speed of 0.80c. How much time would observer have measured for the car to be filled in this case.
A child slides down a slide with the 29 degree incline, and at the bottom her speed is precisely half of what it would have been if the slide had been frictionless. Compute the coefficient of sliding between the child and the slide.
A car drives north at 42 mi/h for 10 {rm min} and then turns east and goes 5.0 {rm mi} at 62 mi/h. at last, it goes southwest at 30 mi/h for 6.0 {rm min}.
What is the minimum time necessary for crossing.
