Construct a 2-4 page paper that fully satisfies these two areas:
A carnot refrigerator takes heat from water at 0 degrees Celsius and rejects heat to a room temperature at 20 degrees Celsius. Assume that 78 grams of water at 0 degrees Celsius are converted to ice at 0degrees Celsius by the refrigerator. Compute th..
A passenger on a moving train tosses a coin with an initial velocity of -2.25 m/s x + 3.58 m/s y, What is the minimum speed of the coin relative to the ground during its flight
A +4.76uC and a -3.84uC charge are placed 22.8 cm apart. Where can a third charge are placed
A 3500 kg block falls vertically through 5 m and then collides with a 400 kg pile, driving it 3.0 cm into bedrock. Assuming that the block-pile collision is completely inelastic, find out the magnitude of the average force on the pile from the bed..
A particle moves so that its position as a function of time is r(t)= i hat + 4(t) ^2 j hat + (t)k hat, What is the shape of the particle's trajectory
A 205-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp isinclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is0.900, and the log has..
Compute the force of gravity between a newborn baby (mass = 4 kg) and the planet Mars (mass = 6.4 x10^23 kg), when Mars is at its position closest to Earth (distance = 8.0 x10^10 m).
A turntable has rotational inertia I and is rotating with angular speed w about a frictionless vertical axis. A wad of clay with mass m is tossed onto the turntable and sticks a distance d from the rotation axis. The clay hits horizontally with it..
In a historical movie, two knights on horseback start from rest 73 m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of 0.15 m/s2, while Sir Alfred's has a magnitude of 0.28 m/s2. Relative to Sir Geor..
A single slit, which is 0.050 mm wide, is illuminated with light of 550 nm wavelength. What is the angular separation among the first two minima on either side of the central maximum?
A space capsule measures the radiation pressure p1 a distance r1 from the center of a spherical light source. what will be the radiation pressure measures
