The Andromeda galaxy is two million light-years from Earth, measured in the common rest frame of Earth and Andromeda. Suppose you took a fast spaceship to Andromeda, so it got you there in 35 years as measured on the ship. If you sent a radio message home as soon as you reached Andromeda, how long after you left Earth would it arrive, according to timekeepers on Earth? My

Draw the rotation curve of two spiral galaxies in one figure. Each galaxy has a stellar disk that extends out to 20 kpc. Galaxy A has twice as much mass within a radius of 20 kpc. Galaxy B shows evidence for the presence of dark matter. Explain and be quantitative?

Analysis: Consider your galaxy rotation curves. Describe how rotational velocity changes as a function of distance from galaxy center. Do all the galaxies show similar behavior? Now compare the galaxy rotation curves to the curve you plotted for the solar system planets. How do they differ? We know that most of the mass (>99%) of the solar system is in the Sun. Is this consistent with the masses you calculated in the first table, and the solar system rotation curve?...

The specific rotation, [α]D, for (-)-2-butanol is +14. What is the observed rotation for a solution of 1.0 g of (-)-2-butanol in 10 mL of water in a sample tube having a pathlength of 10 cm? ??????degrees . The observed rotation of a solution of 1.5 g of a compound in 10 mL of water is +3.4 degrees. If the pathlength is 10 cm, what is the specific rotation of the compound? .

Part #2: Creating a table Background: Prior to storing data in a RDBMS, a table with suitable schema must be created. Exercise: Create a table with your ID (e.g.: derricker) with the following procedure If needed, log onto MySQL RDBMS using the mysql command-line. Create a table to store person information (namely: id, name, and email) by appropriately changing ID in the following command: mysql> CREATE TABLE id (    id    INTEGER NOT NULL,    name VARCHAR(64) NOT NULL,   ...
