A21.6−g sample of an alloy at 93.00°c is placed into 50.0 g of water at 22.00°c in an insulated coffee-cup calorimeter with a heat capacity of 9.20 j/k. if the final temperature of the system is 31.10°c, what is the specific heat capacity of the alloy?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
