(a) With each cycle, a 2430-W engine extracts 2080 J from a thermal reservoir at 90 °C and expels 1510 J into a thermal reservoir at 20 °C. What is the work done for each cycle?
(b) What is the engine's efficiency? (Be sure to enter your answer in decimal format and not as a percent.)
(c) How much time does each cycle take?
An emf is induced in a conducting loop of wire 1.46m long as its shape is changed from square to circular. Find the average magnitude of the induced emf
In the absence of air resistance, a projectile is launched from and returns to ground level. It follows a trajectory similar and has a range of 26 m. Suppose the launch speed is doubled, and the projectile is fired at the same angle above the grou..
A power line, running above the ground at the top of 8.0 m high poles, carries a current of 90 A. What is the magnitude of the magnetic field produced by this wire at the ground
A bag of cement of weight 375 N hangs from three wires as suggested in Figure P5.18. Two of the wires make angles θ1 = 55.0° and θ2 = 25.0° with the horizontal. If the system is in equilibrium, find out the tensions in the wires.
Density is the ratio of an object;s mass to its volume. Would you except density to be a vector or a sdcalar quanity? Explain.
Two metal balls are hung from strings. The first ball, 0.09 kg, is pulled to the side and released so that it strikes the second ball with a speed of 1.62 m/s. What is the mass of the second ball
A crate of mass 150.0 kg lies at rest on a horizontal storage room floor. The coefficient of static friction between crate and floor is 0.72, and the coefficient of kinetic friction is 0.85. (You may suppose g = 10.0m/s2).
When two sticks are laid end-to-end they cover a length of 8.32 feet. What is the length of the shorter stick
A circular coil enclosing an area of 96 cm2 is made of 199 turns of copper wire. The wire making up the coil has resistance of 3.0 , and the ends of the wire are linked to form a closed circuit.
