Consider an isolated composite system consisting of subsystems a and b that can exchange energy with each other subsystem a consists of three noninteracting spins, cach having magnetic moment ! subsystem b consists of two noninteracting spins cach with a magnetic moment 2 a uniform magnetic field h is applied to the composite system (a) suppose that the total energy is e = -3uh what are the accessible - crostates of the composite system? (b) what is the probability p(m) that system a has magnetization m? (5) (c) suppose that systems a and b are initially separated from each other and that the net magnetic moment of a is -34 and the net magnetic moment of b is +4u the systems are then placed in thermal contact with one another and are allowed to exchange energy what is the probability p(m) that the net magnetic moment of systemi a has one of its possible values m? (d) for the situation described in (c), what is the mean value of the net magnetic monent of system a?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
