A confined quantity of air undergoes two thermodynamic processes departing from an initial equilibrium state where the temperature is 20°C, the absolute pressure is 1bar, and the volume is 0.2m3. First, the volume of the system is doubled by an isobaric process. Then, the volume is decreased back to the initial value through a process where the relation P-V1.4 is kept constant. You may assume average values for the particular heat capacities (cp and cv) to:
(a) Sketch the processes in a P-V diagram.
(b) Determine the temperature of the three states in K.
(c) Calculate the total work in kJ.
(d) Compute the total heat transfer in kJ.

newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of
For a negative point charge, the electric field vectors: a) Circle the charge b) Point radially in toward the charge c) Point radially away from the charge d) C
A particle with a charge of -1.5uC and a mass of 2.5x10-6kgis released from rest at point A and accelerates toward point B, Arriving there with a speed of 42m/s. (a) What is the po

Corkscrew Rule: Knowing the direction of the current, it is possible to determine the direction of the magnetic field using Maxwell's Corkscrew rule, usually abbreviated to the
Starting from Maxwell's e-m equation, get the wave equation for E in an ionized medium. Identify the dissipative terms in the equation.
In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency.
The engine on a motorcycle hums at 85 Hz. If the motorcycle travels toward a resting observer at a velocity of 29.6 m/s, what frequency does the observer hear? Use 343 m/s
