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?

Atown is considering building a biodiesel power plant that would burn biomass to generate electricity. which of the following correctly lists an advantage and a disadvantage of this project?

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.

Use the frequency histogram to complete the following parts. ​(a) identify the class with the​ greatest, and the class with the​ least, relative frequency. ​(b) estimate the greatest and least relative frequencies. ​(c) describe any patterns with the data. female fibula lengths 30.5 31.5 32.5 33.5 34.5 35.5 36.5 37.5 38.5 39.5 0 0.05 0.1 0.15 0.2 0.25 length (in centimeters) relative frequency a histogram titled "female fibula lengths" has a horizontal axis labeled "length in centimeters" from 30.5 to 39.5 in increments of 1 and a vertical axis labeled "relative frequency" from 0 to 0.25 in increments of 0.05. the histogram contains vertical bars of width 1, where one vertical bar is centered over each of the horizontal axis tick marks. the approximate heights of the vertical bars are listed as follows, where the label is listed first and the approximate height is listed second: 30.5, 0.02; 31.5, 0.04; 32.5, 0.05; 33.5, 0.13; 34.5, 0.22; 35.5, 0.25; 36.5, 0.13; 37.5, 0.06; 38.5, 0.09; 39.5, 0.01. ​(a) the class with the greatest relative frequency is nothing to nothing centimeters. ​(type integers or decimals. do not round. use ascending​ order.)
