In a heat-treating process, a 1-kg metal part, initially at 1075 k, is quenched in a tank containing 100 kg of water, initially at 295 k. there is negligible heat transfer between the contents of the tank and their surroundings. the metal part and water can be modeled as incompressible with specific heats 0.5 kj/kg-k and 4.2 kj/kg-k, respectively. determine (a) the final equilibrium temperature after quenching, in k, and (b) the amount of entropy produced within the tank, in kj/k

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
