Asystem consisting of 1 kg of a gas undergoes a process during which the relationship between pressure and volume is pl. = constant. the process begins with p1 = 1 bar, v = 1m' and ends with v2 = 3 m'. determine the final pressure, p2, in bar, and plot the process on a graph of pressure versus volume.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
