An engine draws energy from a hot reservoir with a temperature of 1250 K and exhausts energy into a cold reservoir with a temperature of 355 K. Over the course of one hour, the engine absorbs 105 J from the hot reservoir and exhausts 8.7 × 104 J into the cold reservoir.
1) What is the power output of this engine?
2) What is the maximum (Carnot) efficiency of a heat engine running between these two reservoirs?
3) What is the actual efficiency of this engine?
A 20 kg child is on the swing that hangs from a rope 3.5 m long. What is her speed at the bottom of her arc if she swings to out 90 degrees.
A stunt man whose mass is 70 kg swings from the end of a 3.10 m long rope along the arc of a vertical circle. Assume that he starts from rest when the rope is horizontal; find the tensions in the rope that are necessary to make him follow his circ..
A 2500 kg car rounds a flat curve of radius 75 m at speed of 80 km/h. if the pavement is icy and the force of static friction is 6000 n, what is the maximum speed the car could safely go around the curve
An air molecule is moving at a velocity of 444 m/s. How various meters would the molecule move during 7.00 ms (milliseconds) if it didn't collide with any other molecules.
How much work is completed on the box by the applied force
The system is released from rest, and the string moves without slipping over pulley. If the larger mass is traveling at a velocity of 2.25 m/s when it has dropped 1m, how much mechanical energy was lost due to friction in the pulley's axle.
plan a free-body diagram for the charge.
An air-filled pipe is found to have successive harmonics at 1050Hz , 1350Hz , and 1650Hz, It is an open-closed pipe, so What is the length of the pipe
Two capacitors (C1 = 6.00 µF and C2 = 11.0 µF) are now connected in series and to a 9.00-V battery, Find the charge on each capacitor
The top plate is illuminated by monochromatic light of wavelength 544.1 nm. Determine number of dark parallel bands crossing the top plate (including the dark band at zero thickness along the edge of contact between the two plates).
why does d account for the reduction of the distance from 8.5 km to a 0 distance. Is this not a reflection of displacement rather than just distance
At a certain location, the horizontal component of the earth's magnetic field is 4.90 10-5 T, due north. A proton moves eastward with just the right speed, so magnetic force on it balances its weight. Find the speed of the proton.
