An ideal gas is brought through an isothermal compression process. The 4.00 moles of gas go from having an initial volume of 236.3 cm^3 to 125.0 cm^3. If 2178 cal are released by the gas during this process, what are the temperature T of the gas and the final pressure, Pf?
The mass of the motorcycle and driver is 348 kg. Find out the magnitude of the normal force that acts on the cycle.
An electric field of 490000 N/C points due west at the certain spot. What is the magnitude of the force that acts on a charge of -8.3 C at this spot.
The hunter uses a small powerboat that moves at a maximum speed of 9.5 km/h with respect to the water. Illustrate what is the minimum time necessary for crossing?
A cord is wrapped around the rim of a solid uniform wheel 0.300 in radius and of mass 7.80 . A steady horizontal pull of 40.0 to the right is exerted on cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearing..
A tuning fork vibrating at 516 Hz falls from rest and accelerates at 9.80 m/s2. How far below the point of release is the tuning fork while waves with a frequency of 489 Hz reach the release point? Take the speed of sound in air to be 340 m/s.
