Q. Three moles of an ideal monatomic gas are at a temperature of 398 K. After that 2131 J of heat is added to the gas, and 736 J of work is completed on it. What is the final temperature of the gas?

Q. For no apparent reason, a poodle is running at a constant speed of 3.40 m/s in a circle with radius 2.8m. Let v1 be velocity vector at time t1, and let v2 be the velocity vector at time t2

for change in t1 = 0.5s compute the magnitude (to four significant figures) of the average acceleration?

For change in t1 = 0.5s compute the direction (relative to v1) of average acceleration, A(a/v)?
