1. A metal block 2.5 ft square and 1.5 ft deep remains submerged on a body of liquid which consists of a 12-in layer of water above a 10-in layer of mercury. The block of metal weighs 120 lb/ft3. What is the distance (measured from the bottom) of the block within the mercury (s=13.6)?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.
