IfB0= 0, how many of the particles that made it through the first Stern-Gerlachwould make it through the second Stern-Gerlach? Explain. b) Now assumingB0>0 is a fixed positive number, determine the smallest valueofdsuch that 25% of the particles transmitted by the first analyzer are alsotransmitted by the second analyzer. c) Very briefly, explain why particles are transmitted in part b) but not in part a).Page

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
