The 14C atom undergoes an explosion and decays into a nucleus, an electron, and a neutrino. Momentum Is conserved in the process of explosion or decay. The data given show the velocity of the electron (mass = 9.11 e-31 kg), the momentum of the neutrino and the mass of the nucleus. From this determine the speed of the recoiling nucleus.
A charge of 3.0 micro coulombs and a second charge are initially far apart. If it takes 29 J of work to bring them to a final configuration in which the 3.0 micro coulombs is at x = 1.0 mm,
A wrecking ball (weight = 4600 N) is supported by a boom, which might be assumed to be uniform and has a weight of 3600N. As the drawing shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and t..
A dead tree is initially stationary and there is a 30.0-degree angle between the tree and the vertical, How fast is the top of the tree moving (in m/s) just before it hits the ground
A baseball pitcher throws a fastball at a speed of 45.00m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it throughout an almost straight-line distance of 4.0 m. compute the acceleration; assume that it is constant ..
A student uses an audio oscillator of adjustable frequency to measure the depth of a water well. how many antinodes are in the standing wave
A 5 g bullet with an initial velocity of 95 m/s lodges in a block of wood and comes to rest at a distance of 6 cm. assume the bullet undergoes a constant negative acceleration; it slows at a constant rate. How much time does it take for bullet to ..
sound of a single frequency is sent into the system of pipes, one straight, the other consisting of two semi-circular paths of radii 20cm and 30cm. what is the lowest frequency that produces an intensity maximum on the output side
A 25 kg child on a 2.0 m swing is released from rest when the swing supports make the angle of 30.0 degrees with the vertical.
As part of a safety investigation, two 1200 {rm kg} cars traveling at 24 {rm m/s} are crashed into different barriers. Find the average forces exerted on (a) car that hits a line of water barrels and takes 1.80 {rm s} to stop, and (b) car that hits a..
A particle moves along x axis according to equations x =2.00+3.00t-1.00t2, where x is in meters and t seconds. At t=3.00s, determine (a) the position of particle. (b) its velocity, and (c ) its acceleration.
