a) What is the change in entropy of the water?
b) The source of heat isa very massive body at a temperature of 25.0oC. What is the change in entropy of this body?
c) What is the total change in entropy of the water and the heat source?
A rabbit runs in a garden such that the x- and y- components of its displacement as function of times are given by x(t) = -0.45 t2 - 6.5 t + 23.3 and y(t) = 0.35 t2 + 8.3 t + 49.9
