Aboy finds an abandoned mine shaft in the woods, and wants to know how deep the hole is. he drops in a stone, and counts 4 seconds before he hears the "plunk" of the stone hitting the bottom of the shaft. approximately how deep is the shaft? (assume a gravitational acceleration of 9.8 m/s2 and no significant air resistance.)

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
