: multivariate analysis (a) How did Einstein extend Planck's quantum theory to explain the experimental curve for heat capacity of solids which could not be otherwise explained by Dulong-Petit classical model at low temperatures, (b) how then Debye removed the discrepancy of Einstein's model? and (c) how do you explain the microscopic origin of the thermal conductivity of solid materials?

[4/9, 1:13 PM] Qevoh: A physics class has 50 students. Of? these, 17 students are physics majors and 18 students are female. Of the physics? majors, seven are female. Find the probability that a randomly selected student is female or a physics major. The probability that a randomly selected student is female or a physics major is nothing.?(Round to three decimal places as? needed.)

Determine whether the following events are mutually exclusive. Explain your reasoning. Pla Event A: Randomly select a male physics major. Event B: Randomly select a physics major who is 21 years old. EDOC These events mutually exclusive, since Crunc it is possible to select a male physics major who is 21 years old. no physics majors are male. hapter C it is not possible to select a male physics major who is 21 years old. not all physics majors are male. Skills for not every male physics major is 21 years old. Tools for all physics majors are male. every male physics major is 21 yours old.

Sketch the crystal structure of (a) NaCl, (b) CsCl, and (c) Diamond, showing the atomic positions and space coordinates. Briefly (in 3-4 sentences) describe each structure type, number of atoms in each cell and discuss the coordination number (number of 15': nearest neighbors for each atom). You are testing the hypothesis that wood ant population size is the same in oak and maple forests. You measure average population sizes of 10,000 in oak forests, and 15,000 in maple forests . You compare these averages with a t-test, which yields a statistical probability of p = 0.45. You should: () accept the statistical null hypothesis because p > 0.05, so these results are not surprising if the null hypothesis is true. )accept the statistical null hypothesis because p 0.05
