A 196-g aluminum calorimeter contains 612 g of water at 21° C. A 96-g piece of ice cooled to -21° C is placed in the calorimeter, Find the final temperature of the system, assuming no heat is transferred to or from the system
By measuring the spectrum of wavelengths of light from our sun, we know that its surface temperature is 5760 K . By measuring the rate at which we receive its energy on earth, we know that it is radiating a total of 3.93×1026 J/s and behaves nearl..

A sled weighs 100N. It is held in place on a frictionless 20 degrees slope by a rope attached to a stake at the top, the rope is parallel to the slope. What is the normal force of slope acting on the sled.
Calculate the magnitude of the planes acceleration. On a level road with its brakes on, a car traveling at 93 km/hr stops within 87 m when the brakes lock and the car slides.
An arrow is launched vertically upward from a crossbow at 97.9 m/s. Ignoring air friction, what is its instantaneous speed at the end of 10.0 s of flight? What is its average speed up to that moment? How high has it risen? What is its instantaneou..
Mr. Physics drops a rock down a 250-meter deep well. Upon impact with the bottom of the well a short burst of sound is produced with a frequency of 250 Hz. How long after he drops the rock does he hear it hit bottom of the well.
A water-skier, moving at a speed of 9.15 m/s, is being pulled by a tow rope that makes an angle of 37.0° regarding the velocity of the boat (see the Illustrating). The tow rope is parallel to the water. The skier is moving in the similar direction..
