Problem 2.1 (closed system) a piston-cylinder device contains 25 g of saturated water vapor that is maintained at a constant pressure of 300 kpa. a resistance heater within the cylinder is turned on and passes a current i) of 0.2 a for 5 min for a 120 v source. at the same time, a heat loss of 3.7 kj occurs. determine the final temperature of the steam.

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
