The electron in a hydrogen atom makes a transition from the n = 3 state to the n = 2 state Determine the linear momentum of the photon emitted as a result of this transition. (in kg*m/s) A: 5.71×10-28 B: 7.60×10-28 C: 1.01×10-27 D: 1.34×10-27 E: 1.79×10-27 Tries 0/3 Using your result from the previous problem, calculate the recoil speed of the hydrogen atom, assuming it was at rest before the photon was emitted. (in m/s) A: 3.70×10-1 B: 4.18×10-1 C: 4.73×10-1 D: 5.34×10-1 E: 6.03×10-1 PLEASE SHOW ALL WORK
A car travels due east with a speed of 35.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. Find the velocity of the rain
Assume that you wish to fabricate a uniform wire out of .60 g of copper. Assume the wire has a resistance R = 0.300 and all of the copper is used.
Average Speed The average speed is the total distance covered over the time interval it took to cover that distance. Average Speed = total distance / total time. It is 180 kilometers between Long Beach and San Diego.
