2. Explain why a photon and a proton cannot exhibit an elastic collision Show transcribed image...
A proton of mass m undergoes a head-on elastic collision with a stationary nucleus of mass 3m. The speed of the proton is 730 m/s. Find the velocity of the center of mass of the system.
Explain why deuterium (2H) cannot spontaneously transition into a proton and a neutron.
A Photomultiplier tube can detect a single photon, but a photodiode cannot. Why is this? As part of your answer sketch the main components of both devices and describe how they work.
6. Suppose that a 3.64 nm photon moving in the +x direction collides head-on with a 2 x 105 m/s electron moving in the -x direction. If the collision is perfectly elastic, find the conditions after collision. 6. Suppose that a 3.64 nm photon moving in the +x direction collides head-on with a 2 x 105 m/s electron moving in the -x direction.

Explain Label each proton with the predicted splitting pattern it would exhibit in a 1H NMR spectrum.
Question 3 (25 points): 1) (1pt) Explain briefly and in your own words why collision is an issue in random access protocols but not in controlled access protocols. 2) (2pts) Explain briefly and in your own words why collision is an issue in random access protocols but not in channelization protocols. 3) (2pts) What happens if there is a collision during the handshaking period? 4) (5pts) Give 2 reasons that CSMA/CD cannot be used in a wireless LAN? 5) (5pts)...
Classify the three collision types as elastic, inelastic, or completely inelastic. Briefly explain your reasoning. i. Magnetic bumpers ii. Hook and pile bumpers iii. Hook and pile to magnetic bumpers (both)
and explain in detail please. Thankyou! 1. In a perfectly ELASTIC collision between two perfectly rigid objects A) the momentum of each object is conserved B) the kinetic energy of each object is conserved C) the momentum of the system is conserved but the kinetic energy of the system is not conserved D) both the momentum and the kinetic energy of the system are conserved
2. In an elastic collision, energy is not conserved. Where does it go? A) It is transformed into heat and also used to deform colliding objects. B) It is converted into potential energy. C) It is transformed into momentum such that momentum is conserved. D) All of the above. E) None of the above.
2. For an elastic collision, which equation could you use to predict the final velocity of Cart 2, which is initially stationary, given the initial velocity of Cart 1 and the masses of the two carts? Explain and show your calculation. 3. To study collisions, you will use two devices called photogates. How does a photogate work?
