A curling stone is given an initial velocity of 18.4m/s across ice rink. If the coefficient of friction between the stone and the ice s 0.054, how far will the stone travel before it comes to a stop.
Find the center of mass of a triangular lamina with vertices (0,0),(1,0) and (0,2)
if the density function is ρ(x,y)=1+3x+3y
A box contains 58 red marbles, 14 yellow marbles, and 28 blue marbles. All the marbles are of the same size. Three marbles are drawn at random from the box, first one, then a second, and then a third. Determine the probability of getting one red marble, one yellow marble, and one blue marble with replacement.
in a reversible cycle 100 KJ of heat is recieved at 500K then a adiabatic expansion occurs to 400K at which temperature of 50 KJ of heat is recieved , then a further adibatic expansion at 300 K at which temperature of 100 KJ is rejected : (1)find the change in entropy which occurs as the system is restored to its initial state in the remainder of the cycle
