An arrow flies past a person standing on Earth. When at rest with respect to the Earth, the arrow's length measures 1.00 m. What is the arrow's length as measured by the person on Earth when the arrow moves at 2.7 x 108 m/s

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.
