A mole contains 6.02 * 1023 particles (atoms, molecules, etc.). If you wanted to reach Alpha Centauri (4.367 light-years away) by creating a strand of carbon atoms (0.3 nm diameter), how many moles of carbon would you need? (Note: 1 light-year = 9.46 * 1012km)
A cloud of gas has a temperature of 5,000 K. Estimate the width of the hydrogen H-alpha line with an intrinsic wavelength λ = 656 nm. (Note: the typical velocity of hydrogen atoms in a gas with temperature T is about (kT/mH)1/2, where k is Boltzmann constant and mH is the mass of a hydrogen atom, which is approximately the mass of a proton).
What is the ratio of the angular resolution limit of Keck to the angular resolution limit of HST? (Assume they are both observing at the same wavelength.)   [Compute the relevant ratio Keck/HST, express as a decimal, and enter below.] HST orbits at an altitude of 559 km above the Earth's surface. Assume its orbit is circular. Compute its orbital period in hours.   Compute its orbital speed (in km/s).
