During a particular process, the pressure of the gas in a heat engine increases from 1.15×105 Pa to 2.37×105 Pa, while the volume increases from 2.33×10?2 m3 to 2.89×10?2 m3. The pressure-volume graph is a straight line.
(a) What is the work associated with the process? Make sure to include the correct sign.
(b) Is work done on the system, or does the system do work on its suroundings?
A series RLC circuit with a resistance of 280? has capacitive and inductive reactances of 320? and 460? , respectively. What is the power factor of the circuit
Two ants race across a table 62 cm long. One travels at 4.77 cm/s and the other at 2 cm/s. When the first one crosses the finish line, how far behind is second one. What am I trying to solve for distance, speed, or time.
Two identical 30 {rm g} particles each carry 3 {rm mu C} of charge. One is held fixed, and the other is located 1 {rm mm} away and released. Find the speed of the moving charge when it's 1{rm cm} from the fixed charge.
Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.

If an object is moving with constant momentum ‹ 8, ?14, ?4 › kg · m/s, What is the net force acting on the object
At a distance r away from a point charge q, the electric potential is V = 600 V and the magnitude of the electric field is E = 200 N/C
At time t=0 a grinding wheel has an angular velocity of 28.0 rad/sec. It has the constant angular acceleration of 35.0 rad/sec^2 until a circuit breaker trips at time t=1.80. From then on, the wheel turns through an angle of 433 as it coasts to the s..
