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?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
