Acamper is about to drink his morning coffee. he pours 400 grams of coffee, initially at into a 250-g aluminum cup, initially at 16.0°c. what is the equilibrium temperature of the coffee-cup system, assuming no heat is lost to the surroundings? the specific heat of aluminum is 900 j/kg°c. assume that the specific heat of coffee is the same as the specific heat of water.

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
