Questions

I did not understand how to do question #12 and #30 on the Chapter 1 homework. I did not see an example to go by for these questions.

When you ask a question you need to tell me exactly what you do and do not understand about the situation. Not having this information the best I can do is give you some general information about what I think you might need to know.

Question 12 asked for a full (decimal) number in standard units for each of several quantities. For example:

2.3 mm is the same as 0.0023 m 2.30 mm is the same as 0.00230 m, and indicates that the measurement is accurate to 3 significant figure (i.e., that the 0 at the end was indeed the result of a measurement, that the instrument used was capable of distinguishing between 2.29, 2.30 and 2.31, and it turned out to be 2.30).

See if this helps, and let me know if you have additional questions.

One way to make an estimate of window area as percent of wall area would be to make a sketch of a typical side of a typical house, then measure the dimensions of the side and the dimensions of the windows. Figure out the areas.

Quicker and just as good: Make your sketch. Then try to fill the rest of the wall with average-sized windows and see how many windows it takes, compared to how many you originally had in your sketch.

I was just wondering if I did something wrong.

I just accessed your information using your code, so it does work.
