Answer #1

ans: A. Their surfaces are cold enough for hydrogen atoms to be in the ground state.

the lyman series is from ground level to the upper level.so G stars have cold enough for hydrogen atoms for excitation.

    Looking for assistance on the problem. I have come to a few answers but would like a second opinion. Thanks! In interstellar space there are clouds of cold gas (at about 20 K) called dark nebula because they block the light from stars behind them from reaching Earth. A typical diameter fro a dark nebula is about 20 light years and has a density of monatomic hydrogen of 50 hydrogen atoms per cubic centimeter. a.) Estimate the mean free path...

    While studying the particle in a box in this chapter, you CR come up with what you think is a brilliant idea. Suppose the electron in the hydrogen atom is modeled like a par- ticle in a one-dimensional box! You look online and learn that the transition from the first excited state of hydrogen to the ground state emits a photon of wavelength 121.6 nm. (a) From this information, you determine the size of the box in which the electron...

    Take an idealized galaxy made of 1011 sun-like stars distributed in a disk that is 50 kpc in diameter and 1 kpc thick. We wish to build (i.e. with our hands) a scale model of the galaxy substituting a grain of sand and shrinking each star proportionally. (Assume R∗ = 7 × 108 m and Rsand = 1 mm). a) What is the size of the model galaxy’s disk? Practically speaking is this a good scale to use for our model?...
