An important feature of the Carnot cycle is that: A) its efficiency can be 100% B) its efficiency depends on the absolute temperature of the hot reservoir used C) its efficiency is determined by the temperatures of the hot and cold reservoirs between which it works and by the properties of the working substance used, and on nothing else. D) it is an example of an irreversible process that can be analyzed exactly without approximations E) no engine can be more efficient than a Carnot engine operating between the same two temperatures.
A football player runs the pattern by the three displacement vectors, , and . The magnitudes of these vectors are A = 4.00 m, B = 18.0 m, and C = 16.0 m. Using the component method, find out the (1) magnitude and (2) direction of the resultant vec..
At a factory, a noon whistle is sounding with a frequency of 480-Hz. As a car travelling at 79 km/h approaches the factory, the driver hears the whistle at frequency fi. After driving past the factory.
Two charges, and are the distance apart. These two charges are free to move but do not because there is a third charge nearby what should be the magnitude of the third charge and its placement in sequence for the first two to be in equilibrium.
A string is wrapped around the disk of mass m = 1.8 kg and radius R = 0.11 m. Starting from rest, you pull the string with a constant force F = 8 N along the nearly frictionless surface. At an instant when the center of the disk has moved a distan..
A person who weighs 620 N stands at x = 5m, right on the end of a long horizontal diving board that weighs 350 N. The diving board is held up by two supports, one at its left end at x = 0, and one at the point x = 2.00 m.
A ball is thrown directly downward with an initial speed of 8.50 m/s, from the height of 29.5 m. After what time interval does it strike the ground.
Three particles, each with a mass of 0.25 kg, are located at (- 4.0 m, 0), (2.0 m, 0), and (0, 3.0 m) and are acted on by forces, and respectively.
assume a planet had a density that varied with radius according to the equation, ρ =A/r, where A is some constant. Determine a formula that gives the central pressure for this kind of planet.
What is frequency of the fork
A wooden raft has a mass of 85 kg. while empty it floats in water (density 1000 kg/m3) with 61 percent of its volume submerged. What mass of sand can be put on the raft without it sinking.
A college campus features a large fountain surrounded by the circular pool. Two students start at the northernmost point of pool and walk slowly around it in opposite directions.
Strictly speaking, as more and more skyscrapers are being built on surface of earth, does the day tend to become longer or shorter.
