Assume a 100-m tape measures 3 mm too short. Five measurements of a distance give results of 253.294, 253.287, 253.289, 253.284, 253.297 m, respectively. Compute (show details) the following statistical quantities:
i) Mean
ii) Median
iii) Residuals
iv) Standard Deviation

Amass of 1.5 kg of air at 120 kpa and 24Β°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.
