PHYS10121 a) A particle of rest mass m is travelling so that its total energy is 2mc. It collides with a stationary particle of rest mass m to form a new single particle. What is the 2. rest mass of the new particle? 9 marks] b) A photon hits an electron at rest and produces an electron-positron pair according to the reaction γ+ e- e" + e-+e+, what is the smallest possible photon energy for this to occur? You may...
A single 224 U nucleus, initially at rest, emits an alpha particle as it decays into a 220 Th nucleus. There are no other decay products, and the kinetic energy of the alpha particle is measured to be 1.356 × 10 − 12 J . What is the total amount of nuclear potential energy PE nuclear , in joules, that is released in this process? PE nuclear = ___J What is the difference Δ m between the original mass of...
A free particle, having rest mass Mo, is in vacuum and initially at rest in the lab frame S. It undergoes an acceleration under the action of a constant pure force F = (fo, fr, 0.0), where 0 c dt Find its 4-velocity U as a function of time and force. Sketch the graphs of the dependence of normalised 3-velocity 3 v/c and the Lorentz factor y(t) of the particle as a function of time t

(d) A particle of mass m is moving at a speed u and hits an identical particle that is siting at rest. What are their four-momenta in the center of mass frame (e) In the center of mass frame, the collision of the two particles in part (d) causes the particles to fuse and create a single particle with mass M »m (i.e. the two particle turn into one, the opposite of a decay) that is completely at rest in...
In the theory of relativity, the mass of a particle with velocity v ism=mo/(square root ((1- v^ 2)/ c^2))where mo is the mass of the particle at rest and ci s the speed of light. What happens as v goes to c?
An alpha particle collides with an oxygen nucleus, initially at rest. The alpha particle is scattered at an angle of 40.0° above its initial direction of motion, and the oxygen nucleus recoils at an angle of 45.0° below this initial direction. The final speed of the oxygen nucleus is 2.44×105m/s. (The mass of an alpha particle is 4.0 u, and the mass of an oxygen nucleus is 16 u.) What is the final speed of the alpha particle? Tries 0/10...
