A sample of dry air has a temperature of 273K, a volume of 4 m^3 and a pressure of 2 atmospheres. The air parcel then undergoes the following changes: a) warmed under constant pressure to 400K, b) cooled under constant volume to 200K, c) cooled under constant pressure to 100K, and d) warmed under constant volume to 300K. Sketch the process on a P-V diagram and mark the final values for pressure and volume after each change. Calculate the total work done.
The coil is in a uniform magnetic field that is perpendicular to the plane of the coil. Illustrate what rate of change of the magnetic field strength will induce a current of 4.98 A in the coil?
A boat moves through the water of a river at 9 m/s relative to the water, regardless of the boat's direction. If the water in the river is flowing at 1.9 m/s, how long does it take the boat to make a round trip consisting of a 225 m displacement d..
A jeweler working awith a heated 47 g gold ring must lower the ring's temperature to make it safe to handle. If the ring is initially at 99 C, what mass of water at 25 C is needed to lower the rings temperature to 38 c.
A 4 kg model rocket is launched, expelling 40.00 g of burned fuel from its exhaust at a speed of 550m/s. What is the velocity of the rocket after fuel has burned? Hint: Ignore the external forces of gravity and air resistance.
A bar AB of negligible mass and length 2 m balanced at its midpoint a 4 kg and 5 kg masses are suspended from both ends. A 4 kg mass is 0.4m away from the midpoint. At what point the mass of 5 kg is suspended to a bar keep the balance.
A gun shoots bullets that leave the muzzle with a speed of 205m/s. If a bullet is to hit a target 151m away at the level of the muzzle, the gun must be aimed at a point above target.
A 1000N force stretches a wire by 4.0mm . A:A second wire of the same material is twice as long and has twice the diameter. How much force is needed to stretch it by 1.0 mm? B:A third wire of the same material is twice as long as the first and has..
Explain how will the acceleration due to gravity at the surface of planet X compare to the acceleration due to gravity at the surface of earth?
After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost throughout the collision.
Incurred expenses of $220,000 for its alcohol rehabilitation program but paid the expenses from unrestricted resources, not from available restricted resources.
An 10m, 210N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.55, and the ladder makes a 50° angle with the ground. How far up the ladder can an 850N person climb before ladder b..
