A proton confined in a one-dimensional boxemits a 2.0 MeV gamma-ray photon in a quantum jump from n=2 to n = 1. What is the length of the box inmeterss?
Express your answer using twosignificant figures.

asthenosphere and convection

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
