Given an isothermal expansion of gas from 1.0 to 2.0 cubic meters in a piston-cylinder arrangement where pressure varies according to P= 1.2 atm -.062 atm/ m^3 V.
What is the final pressure?
How much work was done by the gas?
How much thermal energy was transferred?
A 50.0 g copper calorimeter contains 200 g of water at 20.0°C. How much steam must be condensed into the water if the final temperature of the system
An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaki..
It is possible to produce artificial gravity on a space station by having the station rotate. Explain how this would work. What would be some benefits and drawbacks to this approach?
The Space Shuttle travels at a speed of about 7.60 103 m/s. The blink of an astronaut's eye lasts about 120 ms. How many football fields (length = 91.4 m) does the Shuttle cover in the blink of an eye?
What would be the equilibrium temperature when a 271 g block of copper at 280°C is placed in a 169 g aluminum calorimeter cup containing 817 g of water at 11.5°C.
compute the distance from the central maximum to the first bright region on either side of the central maximum.
What minimum heat is needed to bring 138g water at 22°C to the boiling point and completely boil it away.
Three equal point charges, each with charge 2.00, are placed at the vertices of an equilateral triangle whose sides are of length 0.650. Illustrate what is the electric potential energy of the system?
Block B rests on a smooth inclined plane of 21 degrees and block A hangs vertically. Compute the acceleration of the system if the mass of block A is 1.08 kg and that of block B is 5.9 kg.
How much longer does the trip take. Find out the acceleration of each mass and the tension in the string that connects them.
A rigid tank contains 1.40 moles of an ideal gas. Determine the number of moles of gas that must be withdrawn from the tank to lower the pressure of the gas from 27.2 atm to 5.90 atm. Assume the volume of the tank and the temperature of the gas re..
A 13 turn circular loop of wire has a diameter of 0.66m. The plane of the circular loop creates an angle of 63 to the Earth's magnetic field. In 0.15s the coil is flipped at a location where the magnitude of the Earth's magnetic field is 34 μT.
