Your least favorite professor likes mountain climbing and plans to do some during Winter Break. There is always the possibility (hope?) he will fall into a crevasse in some glacier. If that happened, you wonder if he would reappear before the end of the academic year. Assume the The distance from the crevasse field to the end of the trailhead where discovery is likely is 1850 m. You decide to build a 1/500 glycerin model to see if you might have to deal with the professor again before the end of the year. Ice has approximately the density of glycerin, but its viscosity is 1,000 times greater. Using your scale model, your model professor reappears after 9.6 hours. When would the real professor reappear?

After years of asking, you finally were allowed to go on a joy ride in your uncle’s 1956 Mercedes-Benz 300 SL. A notable feature of this vehicle is the gullwing door design that opens from a hinge at the top of the car. Unfortunately, you are having so much fun driving the car that you end up submerged in a fresh water lake. You sink to the bottom of the lake, which has a depth of 10 m. For the sake of simplicity, you can model the door as a 1 m × 1 m square plate, inclined at 45° relative to the floor of the lake. Neglect the weight of the door and friction in the hinge. How much force will be required to open the door, assuming you push from its geometric center?

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

You are learning to play the violin. One end of the string is vibrating from the bow running along one end. The other end is tied down. The length of the string we will be looking at is 30 cm and the total mass of the string is 0,32 g. We will be modeling this as a standing wave on a string. You being to play the violin and play a note which has a frequency of 440 Hz. You (having incredible eyesight) see that there are 3 anti-nodes on the string forming a perfect sinusoidal wave (shown in diagram). L i) What is the wavelength of this standing wave? ii) What is the speed of the traveling waves that make up this standing wave? iii) What is the tension of the string? iv) Suppose you increase the tension of the string until you get a new standing wave. Will this standing wave have two antinodes or four antinodes? Explain. (You are still at a frequency of 440 Hz)
