If there are any who missed out on the handouts:
Physics PS
Copy each problem and write your solutions to whole sheet/s of pad paper. Follow the format in problem solving. (Due Feb 26, 2012, Monday)

1. Calorimetry/Heat If the price of electrical energy is P 11.00 per kilowatt-hour, what is the cost of using electrical energy to heat the water in swimming pool (12.0m x 9.00 m x 1.5 m) from 15 to 27 deg. C?
2. Phase Change. An aluminum can with a mass of 0.500 kg contains 0.130 kg of water at a temperature of 80.0 deg. C. A 0.150 kg of ice at -2.0 is dropped into the can. Find the final temperature of the mixture. Assume no heat loss to the surroundings. The specific heat capacities of aluminum, water, and ice are 9.00 x 10^2 J/kg.Cdeg. , 4186 J/kg.Cdeg. , and 2.00 x 10^3 J/kg.Cdeg. respectively. The latent heat of fusion of ice is 33.5 x 10^5 J/kg.
Hint: Q(water) + Q(aluminum) = Q(ice)
3. Thermal Expansion. A brass cylinder is initially 20.0 deg.C. At what temperature will its volume be 0.300% larger than it is at 20.0 deg.C. The coefficient of linear expansion of brass is Alpha(brass) - 2.0 x 10^5 /Cdeg. Note:Beta = 3Alpha
4. Conduction. One end of an insulated (to the environment) metal rod is maintained at 100 deg.C, and the other end is placed in an ice-water mixture. The bar has a length of 50.0 cm and a cross-section area of 0.800cm^2. the heat conducted by the rod melts 3.00 g of ice in 5.00 min. The latent heat of fusion of ice is 80cal/g. Calculate the thermal conductivity k of the metal.
5. Radiation. The supergiant star Betelgeuse has a surface temperature of about 2900 K and emits a radiant power of approximately 4.00 x 10^30 W. Assuming that Betelgeuse is a perfect emitter (e=1) and spherical, find its radius.

CHEM Data For Those Who Didn't Copy

by alrlchoa in

Dear Research Committee

by _waycider in

Our era is the Regency Era, which is 1780's-1830's (debatable, but let's not fuss)

Research: everything from what they're wearing to how their hair is fixed, the differences in the formal and casual wear. Just the general gist of it all, like certain fashion trends and possible reasons (like did you know sleeve ruffles were seen as undemocratic so the guys didn't wear 'em). I'll handle the historical background. Feel free to include pictures! Please cite your sources.

Bing and Lawrence, I'm counting on you guys to do the research for menswear. Aline and Clare, you guys for the women's wear.

And I'll condense everything, fact check, add details, and I guess I'll coordinate with Marketing for canvassing and then Design and Marketing a lot later. What fun.

E-mail it to me, it doesn't have a word count or a certain length-- just make sure you're detailed enough so Design can base a design off it and that we can write a report. This is due Saturday after YMSAT week.
