Heat is transferred in three ways from one place to another. the mechanism of heat transfer whereby atoms or molecules of matter in a hotter part of the material vibrate or move with greater kinetic energy than atoms in the colder part and transfer heat by means of collision of these atoms. what type of heat transfer is this?

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
