Function of rewrite the blackbody power spectrum as a and compute the value amax where the power density dp|dris maximized. find the frequency corresponding to xmax. why is w not equal to wmax, where wmax is given by wmax 2.82 compare amax to 27 c/wmax for a 5780 k black body at temperature

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
