Question

QUANTUM PHYSICS You have accidentally been beamed into an alternative universe, where first graders love broccoli, where high schoolers do all their homework right after school every day, where UCF students actually CAN finish, but in which, sadly, Justin Bieber is still a dweeb. In this mysterious alternate universe, quantum physics still holds but Planck's constant is different kg m2 h= 3.6 8 much larger than in our home universe. Calculate the wavelength of a neutron in this alternate universe when the momentum of the neutron is Pn = 1.44 x 10-5 kg m S Type in the numeric part of your answer to the nearest kilometer. E.g., if your wavelength is X=560850 m, then type in 561.

Answer 1

Wavelength of the neutron P, = 250000m 3.6 1.44 x 10-5 in = 250km F F me V V2 When two skateboarders of different masses push off from each other according to Newton's law they exert an equal and opposite forces F on each other. Since forces are equal in magnitude and opposite in direction therefore therefore momentum of the system remains conserved Fnet 0 dP 0 dt P = conserved P Р system system est pas 1,i+ 1,1 2.4" 2.1 (tortu-Part 2,1 -AP1 = 4P2

Therefore the skateboarders exchange equal but opposite amounts of momentum Now -4 P = AP2 -m4 vi = m 24 V2 Since m 7 m2 A vi # 4 v2 Skateboarders doesn't exchange equal velocity Answers The skateboarders exchange equal but opposite amounts of velocity False The skateboarders exchange equal but opposite amounts of momentum True According to Newton's third law their interaction forces are of same size
