Description

**A++ Work! 100% CORRECT PHYSICS TUTORIAL

INCLUDES ANSWERS TO THE FOLLOWING QUESTIONS

1) The specific heat capacity of ice is about 0.5 cal/g ??C. Suppose it remains at that value all the way to absolute zero. Show that the heat required to change a 1-g ice cube at absolute zero(-273 ?C)to 1 g of boiling water is 320 cal.

1] A 10 N force acts on a 2 kg object for 3 seconds. If the object was initally at rest, the momentum of the object after 3 seconds is ____ kg m/s. (10 points)

[2] A 10 N force acts on a 2 kg object for 3 seconds. If the object was initally at rest, the velocity of the object after 3 seconds is ____ m/s. (10 points)

found in part 1:

[3] A 10 N force acts on a 2 kg object for 3 seconds. If the object was initally at rest, the KE of the object after 3 seconds is ____ J. (10 points)

[4] A 10 N force acts on a 2 kg object for 3 seconds. If the object was initally at rest, the work done in this process is ____ J. (10 points)

[5] A 10 N force acts on a 2 kg object for 3 seconds. If the object was initally at rest, the calculated power in this process is ____ W. (10 points)
