Imagine that you have obtained spectra for several galaxies and have measured the observed wavelength of a hydrogen emission line that has a rest wavelength of 656.3 nanometers. Here are your results:

Galaxy 1: Observed wavelength of hydrogen line is 658.7 nanometers

Galaxy 2: Observed wavelength of hydrogen line is 664.2 nanometers.

Galaxy 3: Observed wavelength of hydrogen line is 683.6 nanometers.

Part D: Estimate the distance to each galaxy from Hubble's law. Assume that H0=22km/s/Mly.

Express your answers using two significant figures. Enter your answers numerically separated by commas.

(dgalaxy1, dgalaxy2, dgalaxy3 = *Answer* Mly)

Suppose that you have obtained spectra of several galaxies and have measured the observed wavelength of the H-alpha line (rest wavelength = 656.3nm) to be: Galaxy 1: 659 nm. Galaxy 2: 666.5 nm. Galaxy 3: 676.6 nm. 10. [4pt] Calculate the redshift, z, for each of these galaxies. 11. [4pt] Calculate the radial velocity of each of these galaxies. 12. [4pt] Assuming a Hubble Constant of 69.6 km/s/Mpc, cal- culate the distance to each of these galaxies (answer in Mpc).

Imagine that you are studying a species of guppy in which mature males are observed to have bright orange tails, while females and immature fish have grey tails. You decide to test whether sexual selection can explain this dimorphism. a) Describe an experiment to test this hypothesis. Include details about what you will measure. Draw and label two diagrams: one showing potential data that would refute your hypothesis, the other showing potential data that would support it. b) A competing...

PHYS 1403 (stars and galaxies. As you have read the text book and course notes you realize how important words are to describe ideas clearly. But a picture lends so much more interest and clarity! For this forum we want you to use both skill sets – the ability to describe in words and choose a picture. Go to the Glossary of the text book and pick any word you want to learn about. Quote the definition in the book...

We have studied several ways in which elasticity is measured in economics. The concept can be used to study other relationships between two things—along as each is measurable and they affect one another.. The importance is that elasticity allows us to put a number on the relative way in which one thing affects the other. Is it a positive effect? How strong is that effect? Think of two things you know about in your life. It could be from your...

One of Marjorie's friends suggested the try in vitro fertilization (IVF), because she was successful in having a child with this method. "isn't that expensive" ? Marjorie asked.
