Ahot lump of 35.8 g of copper at an initial temperature of 70.7 °c is placed in 50.0 ml h2o initially at 25.0 °c and allowed to reach thermal equilibrium. what is the final temperature of the copper and water, given that the specific heat of copper is 0.385 j/(g·°c)? assume no heat is lost to surroundings.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
