Which of the following changes would increase the probability of transmission of a particle through a potential barrier? (You may choosemore than one answer.) (a) decreasing the width of the barrier (b) increasingthe width of the barrier (c) decreasing the height of the barrier (d) increasingthe height of the barrier (e) decreasing the kinetic energy of the incident particle (f) increasing the kinetic energy of the incident particle
Although all energy is kinetic and potential* it is convenient to break it up into
coherent macroscopic kinetic energy (KE),
macroscopic potential energy (PE),
thermal energy (ThE = kinetic and potential energy of molecules due to random motion),
chemical energy (ChE = kinetic and potential energy of electrons in atoms in molecule).
Consider a small rocket placed on a pad containing an electrical igniter. The rocket is attached to a small packet of chemical explosive in its tail. The igniter lights a short fuse that ignites the chemical explosive shooting the rocket upward. It rises straight up about 50 feet, then falls to the ground where it bounces and comes to a stop.Consider three times:
t0 = just after the explosion has completed but the rocket has not risen much
t1 = the rocket is just at the top
t2 = the rocket has fallen to the ground and come to a stop
Identify what has happened to the various energies of the rocket (not including the explosive packet or fuse) from the…
