Students have asked these similar questions
(a) There are about 3 × 10
25 molecules of air in each cubic meter of the atmosphere. If each
molecule had its own cube of space, what is the length of one side of the cube? (b) How many
times greater is the length of a side of the cube than the length of a molecule that is about 3 × 10
-10
m long?
An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads. When the photograph is taken, the angle of elevation of the sun is 43 degrees. By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 64 feet long. How tall is the bulding? (Round your answer to two decimal places.)
Estimate how many molecules of air are in each 2.5-L breath you inhale that were also in the last breath Galileo took. [Hint: Assume the atmosphere is about 10 km high and of constant density.]
Express your answer using two significant figures.
N=?? (I got 27, but I was also wrong).

- Paperweight I bought a pack of 100 rectangular index cards. Each card measured 15 by 10 cm. The pack said ：Paper Density = 200 GSM (grams per square meter). This means that a square meter of those cards weighs 200 g. A) All of the cards in the pack are place flat on a table without overlap. In square meters, what is the total area of the table covered by the cards? B) Each pack of cards is wrapped in a sheet of 50 GSM paper with an area of 800cm squared. I have a number of packs and wish to store them on a shelf that cannot hold more than 10 kg. What is the largest whole number of wrapped packs that can be stored?

The payload contains an altimeter and a digital barometer. From one of the University’s class room where they built a data receiving area, the altimeter sends 10 values of altitude, 5600 ft, 5000 ft, 4600ft, 4100 ft, 3800 ft, 3500 ft, 3150 ft, 2900 ft, 2300 ft, and 1300 ft.
