A hydrogen atom (particle 1) is initially at rest. A neutron (particle 2) initially moves to the east at speed v, colliding with the hydrogen atom. Immediately after the collision, the neutron is moving to the south, and the hydrogen atom is moving at an angle ? north of east. The mass of the hydrogen atom is twice the mass of the neutron. Determine the particles’ final speeds, v1 and v2, in terms of v and/or ? only.
Two waves with identical frequency but different amplitudes A1= 5.0cm and A2 = 3.0 cm, what is the amplitude of the resulting wave if they interfere constructively
Helium-Neon laser: "Lambda"= 632.8nm. We can observe the first order maximum at "theta"= 25 degrees. What is the second order maximum angle
A 50g ball of clay is thrown horizontally at 40m/s toward a 1.5kg block sitting at rest on a frictionless hi surface. The clayts and sticks to the block. What impulse does the clay exert on the block
In one such test, 150 turns of wire were wrapped around a 7.0-m-diameter cylindrical shark tank. find the magnetic field strength in the center of the tank
In a pool game, the cue ball, which has an initial speed of 8 m/s, make an elastic collision with the eight ball, which is initially at rest. Find the direction of motion of the cue ball after the collision
For a rough calculation, we shall assume that the doctor is 50 from the baby (she is likely to be even closer at delivery), has a mass of 75.00, and can be modelled as a uniform sphere.
A uniform magnetic field B is confined to the square region with side of length 2L.
For tests using a ballistocardiograph, a patient lies on a horizontal platform that is supported on jets of air. Because of the air jets, the friction impeding the horizontal motion of the platform is negligible. determine the recoil velocity
A 10 microcoulomb charge is placed at the origin and a 20 microcoulomb charge is placed on the x-axis at x = 40 cm. what is the magnitude of the force it will experience
A truck is traveling on a level road. The driver applies the brakes causing the truck to decelerate by an amount g/2. This causes a box in the rear of the truck to slide forward. If the coefficient of sliding friction between the box and the truckbed..
Consider the concentric metal sphere and spherical shells. The innermost is a solid sphere that has a radius R1. A spherical shell surrounds the sphere and has an inner radius R2 and an outer radius R3.
Two atomic clocks are synchronized while on Earth before one is launched (within a GPS satellite) into a medium-altitude Earth orbit. estimate the time difference between the two atomic clocks
