Superheated water vapor at 180 psia and 500f is allowed to cool at constant volume until the temperature drops to 250°f. at the final state, determine (a) the pressure (b) the quality, and (c) the enthalpy 55e). also show t-v diagram with respect to the saturation lines.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
