A rigid iron cylinder contains propane gas. The cylinder and thegas are in thermal equilibrium. In a process, 8700 J of heatare transferred to the cylinder and the gas, so that at the endthey are again in thermal equilibrium, with a temperature increaseof 24 K. If the mass of the cylinder is 0.51 kg, how many moles of propane are there in the cylinder?
You have a string with a mass of 0.0141 kg. You stretch the string with a force of 9.09 N, giving it a length of 1.81 m. What is the wavelength of the standing wave
A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 3.7 × 104 kg, and the force causes its speed to change from 7600 to 5500 m/s. What is the work done by the force
Light shines through a single slit whose width is 5.6 104 m. A diffraction pattern is formed on a flat screen located 4.0 m away. What is the wavelength of the light
A heater runs on an AC voltage of 120 V and draws a power of 26 W. If this heater were run instead on a DC voltage of 70 V, how much current would flow through the heater? Hint: The heater can be modeled as a resistor.
You make a capacitor by cutting the 14.5 cm--diameter bottoms out of two aluminum pie plates, separating them by 3.30mm , What's the capacitance of your capacitor
A 1328.0 g mass is on a horizontal surface with μk = 0.32, and is in contact with a massless spring with a force constant of 550.0 N/m which is compressed. Calculate the distance the spring was compressed
A power station uses 100 kV to deliver power to a building. The building has a total resistance of 12.5kV. How much power is delivered to the building
Assuming frictionless conditions, a table has a hanging mass, m1, over a pulley at the left side and another hanging mass, m2, over a pulley on the right side.
