A three-step cycle is undergone by n moles of an ideal diatomic gas: (1) the temperature of the gas is increased from T_1 to T_2 at constant volume; (2) the gas is then isothermally expanded to its original pressure; (3) the gas is then contracted at constant pressure back to its original volume. Throughout the cycle, the molecules rotate but do not oscillate. What is the efficiency of the cycle in terms of T_1 and T_2?
Compute the mass of a ball and speed of a puck after collision.
A loudspeaker of mass 24.0 {rm kg} is suspended a distance of h = 1.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.70 {rm m}.
Two long, parallel wires, each with the mass per unit length of 43 g/m, are supported in a horizontal plane by 6-cm long strings. Each wire carries the similar current, I, causing the wires to repel each other so that the angle, θ, between the sup..

Two capacitors (C1=1.00 ?F and C2=2.00 ?F) are charged with Q1=3.00 ?C on the positive plate of capacitor 1 and Q2=3.00 ?C on the positive plate of capacitor 2, find the total charge on the positive plate of capacitor 1
A copper telephone wire has essentially no sag between poles 34.00 m apart on a winter day when the temperature is -20°C. How much longer is the wire on a summer day.
What is the capacitance of this capacitor. Estimate the terminal speed of a wooden sphere (density 0.810 g/cm3) falling through air, if its radius is 8.00 cm and its drag coefficient is 0.5.
A 1200g model rocket is resting horizontally at the top edge of a 40-m-high wall when it is accidentally bumped, How far from the base of the wall does the rocket land
Coherent light with wavelength 609nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3- {rm m} from the slits. The first-order bright fringe is a distance of 4.84 {rm mm} from the center of ..
Three point charges Q1 = 2.2 mu or micro C, Q2 = 4.2 mu or micro C and Q3 = 3.2 mu or micro C, are arranged as shown
A rod of length L is hinged at one end. The moment of inertia as the rod rotates around that hinge is ML2/3. Suppose a 2.00-m rod with a mass of 3.00 kg is hinged at one end and is held in a horizontal position. The rod is released as the free end is..
