6.5 kg chunk of ice at -12 degrees Celsius is placed in a 0.22 kg of water at 22 degrees Celsius. Ignore any heat flow with the surroundings, including the water, assume the final mixture is ice. Determine the following: a. heat lost or gained by ice b. heat lost or gained by water A 0.35 kg mass is attached to a spring is set up horizontally on a friction less table. The mass is pulled so that the spring is stretched from the equilibrium point, and is then released from rest. If the mass reaches a maximum velocity of 2.1 m/s, and is oscillating with an angular frequency of 5.6rad/s and the stopwatch is started at x = 0.34 m away from the equilibrium position. determine the phase content
