N an empty rubber raft the pressure is approximately constant. You push on a large air pump that pushes 1.0 L(1.0× 10-3m3) of air into the raft. You exert a 15 N force while pushing the pump handle 6.0×10-2 m .
Determine the work done on the gas.
If all of the work is converted to thermal energy of the 1.0 L of gas, what is the temperature increase of the gas? Assume that the air obeys the ideal gas law and is initially at 293 K.
An alpha particle (q = +2e, m = 4.00 u)travels in a circular path of radius 4.88 cm in a uniform magneticfield with B = 1.00 T. Calculate (a) itsspeed, (b) its period of revolution
A 750 air-track glider attached to a spring with spring constant 10.5 is sitting at rest on a frictionless air track. A 475 glider is pushed toward it from the far end of the track at a speed of 118 .
A 150 g mass attached to a spring with a force constant of 45.0 N/m vibrates on a horizontal, frictionless surface in simple harmonic motion with amplitude of 5.00centimeter. Evaluate the maximum speed and acceleration of the mass
