Pressure Temperature (Isochoric Process) In a piston-cylinder device, 0.002 lbm of air and a fuel burn, releasing 0.45 Btu of heat at constant volume. If the pressure is 80 psi and the temperature is 300°F before burning, determine: a. The final pressure
b. The temperature.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
