An ideal, monatomic gas is allowed to expand quasi-statically and adiabatically from an initial volume Vi = 1.6 liters and initial temperature Ti = 320 K to a final volume of Vf = 7.2 liters. If there are n = 1.5 mol of gas, What is the work done by the gas? What is the change in the internal energy of the gas?
A 3.00 x 102-kg piano is being lifted at a steady speed from ground level straight up to an apartment 10.00 m above the ground. The crane that is doing the lifting produces a steady power of 4.00 x 102 W. Explain by how much time does it take to li..
A car of mass M= 900-kg travelling at 45.0 kmh enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between road and car's tires.
A 145 g wire is held under a tension of 258 N with one end at x = 0 and the other at x = 13.0 m. At time t = 0, pulse 1 is sent along the wire from the end at x = 13.0 m. At time t = 30.9 ms, pulse 2 is sent along the wire from the end at x = 0. A..
Determine the magnitude of the total initial momentum of the two-block system. Find , the magnitude of the final velocity of the two-block system. What is the change in the system's kinetic energy due to the collision?.
Two large parallel plates stand side by side with a distance of 2.10 cm between them, Find the acceleration of the electron, Find the magnitude and direction of the electric field in the region between the plates
The hunter uses a small powerboat that moves at a maximum speed of 14 km/h with respect to the water. Illustrate what is the minimum time necessary for crossing?
The link between portfolio level objectives with portfolio success factors that are achieved through individual projects and points out how contributes to strategic fit, use of synergies, etc.
A uniform soda can of mass 0.138-kg is 11.80-cm tall and filled with 1.30-kg of soda. Then small holes are drilled in the top and bottom (with negligible loss of metal) to drain soda. (Initially the soda can is full.)
To see that it is easy to break a thighbone when falling in this fashion, find out the greatest distance through which his center of gravity can fall without his breaking a bone.
An 8m, 290 N uniform ladders rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.75, and the ladder makes a 50° angle with the ground. How far up the ladder can a 720 N person climb before the lad..
If the car starts at height h= 3.00 R and the radius is R_1 = 24.0 m, compute the radial acceleration of the passengers while the car is at point C, which is at the end of a horizontal diameter.
A car started frm rest and accelerated for 5s at 6.00m/s2.Then it stayed at a constant speed for 20 s. It next slowed down at 3m/s2 until it came to a stop? how far did it travel during the first 5 s.
