Q. A particle of mass M decays into two identical particles each of mass m, where m = 0.4M. Prior to the decay, the particle of mass M has a total energy of 4Mc2 in the laboratory reference frame. The velocities of the decay product are along the direction of motion M. Find the velocities of the decay products in the laboratory reference frame. (Round your answer to three decimal places.)
Write a general expression of the flux
Examine whether it is reasonable to ignore the effects of gravity for each particle. Evaluate the paths travelled by electron and proton and explain the differences.

The sun is more massive than the moon, but the sun is farther from the earth. Which one exerts a greater gravitational force on a person standing on earth? Give the answer by determining the ratio Fsun/ Fmoon of magnitudes of gravitational forces.
A 4.79 crate is suspended from the end of a short vertical rope of negligible mass. An upward force is applied to the end of rope, and the height of the crate above its initial position is given by + (0.61) what is the magnitude of the force when ..
A proton is initially at rest at a point where the potential is 515V. Sometime later the proton is at a point where the potential is 190V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy.
The aurora is caused when electrons and protons, moving in earth's magnetic field of 5x10^-5 T, collide with molecules of the atmosphere and cause them to glow. What is the radius of the circular orbit for (a) an electron with speed 1.0×10^6 and (b) ..
