In proton-antiproton annihilation, a proton and an antiproton (a negatively charged particle with the mass of a proton) collide and disappear, producing electromagnetic radiation. Each particle has a mass of 1.67Ã-10âˆ'27{\rm kg} and they are at rest just before the annihilation.
Part A Find the total energy of the radiation. Give your answers in joules
Part B Find the total energy of the radiation. Give your answers in electron volts.
A 0.33-m-long violin string has a mass of 0.89 g. The peg exerts a 45 N force on it. Determine the lowest frequency sound produced by the vibrating sting
The electric field between the plates of the velocity selector is 4900 V/m, and the magnetic fields in both the velocity selector, compute the radius r of the path for a singly charged ion with mass m = 4.29 10-26 kg
A 27 pound meteorite struck a car, leaving a dent 26cm deep in the trunk. If the meteorite struck the car with a speed of 620m/s, what was the magnitude of its deceleration, assuming it to be constant.
At one point in a pipeline, water's speed is 3.30 m/s and the gauge pressure is 4.00×10^4 Pa. Find out the gauge pressure at a second point in the line 13.0 m lower than the first if the pipe diameter at the second point is twice that at the first.
Because a concave lens cannot form a real image of a real object, it is difficult to measure its focal length precisely. What is the focal length of the concave lens
A rotating cylinder about 25 km long and 9 km in diameter is designed to be used as a space colony. with what angular speed must it rotate so that residents on it would experience the same acceleration due to gravity as on earth? In radians per se..
Two children tug on a toy of mass 2.0 kg. Costa pulls with a force of 10.0N [W 30degrees S]. The toy slides with an acceleration of 2.5 m/s^2 in the direction of the net force.
What focal length does the lens need. how many meters will the car have moved before it begins to slow down.
The switch in a circuit has been open for a long time. The resistors in the circuit each have a value of 60 Ohms, find the total equivalent inductance of the circuit
calculate the fraction of which is submerged when the cylinder floats in alcohol. Fraction of Vwood submerged.
A bumper car with mass m1 = 102 kg is moving to the right with a velocity of v1 = 4.9 m/s. A second bumper car with mass m2 = 90 kg is moving to the left with a velocity of v2 = -3.3 m/s, What is the velocity of the center of mass of the system
A particle has an acceleration of 6.19 m/s^2 for 0.350 s . At the end of this time the particle's velocity is 9.26 m/s What was the particle's initial velocity?
