Q. What is the final equilibrium temperature when 12 g of milk at 20 degrees C is added to 180 g of coffee at 92 degrees C? assume the specific heats of milk and coffe are the same as that of water, and neblect the specific heat of the container?
Q. A light ray of wavelength 598 nm is incident at angle theta on the top surface of a block of polystyrene surrounded by air. a) find maximum value of theta for which the refracted ray will undergo total internal reflection at the left vertical face of the block b) repeat the calculation for the case in which the polystyrene block is immersed in water. c) What happens if the block is immersed in carbon disulfide?

Water runs out of the horizontal drainpipe at the rate of 120 liters per minute. It falls 3.20 m to the ground. Assume the water doesn't splash up, what average force does it exert on the ground? (1 liter = 1 kg.)
As part of a safety investigation, two 1900 cars traveling at 25 are crashed into different barriers. Find out the average forces exerted on (a) car that hits a line of water barrels and takes 1.8 to stop, and (b) car that hits a concrete barrier an..
A pump, submerged at the bottom of a well that is 34 m deep, is used to pump water uphill to the house that is 50 m above the top of the well, as shown above. All pressures are gauge pressures. Avoid the effects of friction, turbulence, and viscosity..
