Calculate the total energy released when 20 g of steam condenses to water cools and then turns to ice at 0°C

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Select the correct answer. what does the process of natural selection involve?
