Asubject mass m is embedded in an infinite homogeneous sea of field stars with number density n(m)dm in the mass range (m, m+dm). the field stars of all masses have a maxwellian df with dispersion a. thus the field stars are not in thermal equilibrium, which would require that a2 is inversely proportional that the subject example, if m > m) let us assume, however, to m star is in thermal equilibrium with the field stars (this could occur, for (a) show that the dispersion of the subject star is dm m2n(m м f dm mn(m) (7.217) (b) show that the df of the subject star is maxwellian

What is the most useful equation for electric power?

Properties seen when one one substance changes to another are known as properties

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
