An insulated rigid tank initially contains 1.4-kg saturated liquid water and water vapor at 200°c. at this state, 25 percent of the volume is occupied by liquid water and the rest by vapor. now an electric resistor placed in the tank is turned on, and the tank is observed to contain saturated water vapor after 20 min. determine:

(a) the volume of the tank

(b) the final temperature

(c) the electric power rating of the resistor

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
