Problem 48. How big
is the Moon?
Estimates and orders of magnitude: Four astronauts are in a spherical space station. (a) If, as is typical, cach of them
breathes about 700 cm of air with each breath, approximately what volume of air (in cubic meters) do these
astronauts breathe in a year? (b) What would the diameter (in meters) of the space station have to be to contain all
this air? (c) With the diameter of the space station obtain from part (b), how long the air would last? (d) Suppose
the space station can support 4 astronauts within the time interval obtain at part (c), how many astronauts will be
required to stay in the space station for them to supply a decade worth of air to breathe?

- When nonmetric units we used in the United Kingdom, a unit of mass called the pound-mass (lbm) was used, where 1 lbm = 0.4539 kg.

(b) Based on that percent uncertainty, what mass in pound-mass has an uncertainty of 1 kg when converted to kilograms?arrow_forwardIn SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .arrow_forwardA generation is about one-third of a lifetime.
