Question
1.In an alternate universe speed of light is different. Would an equivalent relation between frequency and wavelength still hold? If yes, why? If no, why? Establish your point by itemizing your argument.
2. Is gravity a mere theory? Do you believe in it, if so, why? If not, why not? What signs would you look for to validate your opinion?
3. Print out (preferably in color) the sky map of X ray Chandra telescope.
http://chandra.si.edu/photo/map/ (25)
Locate the following:
Coma cluster
M31
M42
Abell 30
Rosette Nebula
List the following properties about the all the objects above, in a TABULAR form:
Location, distance, object type, three most interesting scientific fact about the object.
4.
a) Surface temperature of a star (lets call it V) is 10,000 K. What can you say about the wavelength of all the photons coming out of the star? I need more than just a number in this answer.
b) What is the Luminosity of a star? If for some reason, the temperature of V drops to 5000 K. If the radius of the star does not change, then what happens to the Luminosity? Please quantify.
c)What does it mean by the Flux of a star? In the case of b), what happens to the Flux as the temperature drops? Please be precise.
d)Now imagine that you are standing d distance away from V. How would you see the change in flux as the temperature drops to 5000K ? Be precise and quantify your answer.
5. If the mass of the earth was smaller by a factor of 4, what will happen to the escape velocity? Assume that the radius did not change. Now, assume that the radius did change to keep the density (mass/volume) constant. What happens to the escape velocity? Be precise and quantify.
6. If I gave you an alien solar system and the following information:
There is one main star, its size, and temperature
There are four planets near it and their distances from the star
The albedo of the planets
Masses and Sizes of the planets.
Draw a flow chart to show how you will attempt to explore what gases (usual ones from the periodic table) live on those planets (if any).
Make an itemized section to describe possible uncertainties that may come up in your approach.
Your answer must be to the point, clear and concise.
