A heat engine with 0.1 99 moles of a monatomic gas undergoes the cyclic procedure shown in the pV diagram on the right. Between stages 3 and I the gas is at a constant temperature, and between 2 and 3 no heat is transferred in or out. The temperature of the gas at stage 2 is 365 K.
What is the type of each process in the cycle?
What is the work per cycle of this heat engine?
The angular velocity of the rotor changes from ω0=300rad/s to ω1=150 rad/s'> in a time interval Δt1=2.0 minute'> as the rotor slows to rest at constant acceleration. Find how many revolutions do the blades make in coming to rest from the initial ve..
Tarzan is in the path of a pack of stampeding elephants when Jane swings in to the rescue on a rope vine, hauling him off to safety. The length of the vine 25 m, and Jane starts her swing by the rope horizontal. If Jane's mass is 54kg, and Tarzan's..
