2 kg of a saturated mixture aat 200 kPa and 20% quality is heated at a constant temperature until it becomes a saturated vapor.
a) Sketch the process path on a P-V diagram. clearly indicate the position of the states relative to the 2-phase dome(vapor dome).
b) Find the total work transfer(kJ) during the process(indicate direction and magnitude) as well as total heat transfer.
c) Alter the diagram to show the continuation of heating at constant T. What phase does it become? would the work generated be greater or less for the constant T process than the constant P process? Explain.
During launches, rockets often discard unneeded parts. A certain rocket starts from rest on the launch pad, What total distance did the canister travel between its release and its crash onto the launch pad
A 9.0 V battery moves 20mC of charge through a circuit running from its positive terminal to its negative terminal. How much energy was delivered to the circuit?

a styrofoam box has a surface area of 0.88 m2 and a wall thickness of 2.0 cm. the temperature of the inner surface is
A spring is compressed by 0.0527 m and is used to launch an object horizontally with a speed of 2.19 m/s. at what angular frequency (in rad/s) would it oscillate
A heavy mass in free fall does not fall faster than a light mass. The extra weight is compensated for by extra resistance. A heavy mass on a frictionless plane does not slide down faster than a light mass. A heavy ring and a light ring both roll d..
A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 83 rad/s. The wheel is run at that angular velocity for 29 s and then power is shu..
Two charges q1 = 7 µC, q2 = -33 µC, are L = 14 cm apart. A third charge is to be placed on the line between the two charges. How far from q1 should the third charge be placed so that the net electric force on the third charge is minimized?
A chair of weight 135 lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of = 38 directed at an angle of 42 below the horizontal and the chair slides along the floor.
How large an inductance, in henrys (H), should be connected in series with a 120 V, 60 W lightbulb if it is to operate normally when the combination is connected across a 240 V, 60 Hz line? (First determine the inductive reactance required. You may n..
