1) A vessel contains 32 grams of dry ice (solid carbon dioxide) at T = -78°C, the temperature where it transitions between a solid and a gas at atmospheric pressure. How much energy is required for the carbon dioxide to sublimate? (Ls = 136.38 cal/g)
2) A 35.8 gram piece of iron is placed in a calorimeter filled with 72.1 grams of water at room temperature (23°C). The water heats up and then stabilizes at a temperature of 27°C. Assuming no heat loss to the room or the calorimeter itself, what was the original temperature of the iron sample?
3) A piece of ice weighing 31.9 grams is placed in a calorimeter with 130.7 grams of water at 54.4 degrees Celsius. Assuming no losses and that the calorimeter is perfectly insulated, what is the final temperature?
A current with sinusoidal time-dependence, whose peak value is 5.55 A and frequency is 775 cycles per second, Calculate the average power dissipated by the loop, if its resistance is 64.3
A 5 kg mass attached to a horizontal spring is pulled from its equilibrium position by 3 m and let go. what is the maximum velocity of the mass
A meterstick (L = 1 m) has a mass of m = 0.133 kg. Initially it hangs from two short strings: one at the 25 cm mark and one at the 75 cm mark. What is the tension in the left string right after the right string is cut
A 3 kg toy car with a speed of 5 m/s collides head-on with a 2 kg car traveling in the opposite direction with a speed of 5 m/s, how much kinetic energy is lost
