Document Summary

Moral theories/decision making is just another kind of knowledge. Our two questions of morality and god"s existence are both also forms of knowledge. Very basically we can divide how we can know things into two camps. One is reason and the other is sensation. Proofs for god"s existence can be divided into rational and empirical categories as well. Such as the cosmological argument (rationalist) or the teleological argument (empirical). Moral theories also can be divded in terms of rational and empirical categories as well. Such as kant"s moral theory that is dependent on reason or hume"s theory which is dependent on feeling or sensation. The kinds of propositions or statements or sentences. Propositions were divided into a matrix of four categories. Two have to with a term in the proposition and the others have to do with the way we know them. For every statement there is a subject term and there is a predicate term.

We now see that the requirement that the total eigenfunction isantisymmetric with respect to the exchange of the labels of the twoelectrons effectively leads to a coupling between their spin andspatial coordinates. The electrons act as if they move under aforce whose sign depends on the relative orientation of theirspins.
This section is the bonus section for question 1. Consider thehelium atom which is a two- electron atom as we have discussedabove. The ground state is
1s2.
(k) Referring to your list of the s and t total eigenfunctions,write the ground state wave
function for He. Why is this one the only wave function for theground state?
We will now consider the Coulomb electron repulsion in ourtwo-electron atom. You are certainly not expected to do a detailedperturbation theory calculation.

(l)However,justarguingfromyourqualitativeknowledgeofthesandtstates,whichdoyou expect, in general cases other than the ground state, to havethe lower energy and why?

Introduction. Telescope time is a valuablecommodity in astronomy, so astronomers plan their observationscarefully. One of the first steps is to choose what type ofobservation to make. Recall that three basic types of astronomicalobservation are imaging (taking a photograph of anobject), spectroscopy (spreading an object's light into aspectrum), and timing (measuring how an object's lightvaries with time).

Part A: Sort each of the astronomical questionsbelow into the appropriate bin based on the type of observation youwould need to perform to answer it.

Three Categories: Imagine, Spectroscopy andTiming

The Questions:

1. "What are the major surface features of Mars?"

2. "What is the temperature of Jupiter's atmosphere?"

3. "Does the star Mira vary in brightness?"

4. "How large is the Andromeda Galaxy?"

5. "What is the chemical composition of the Crab Nebula?"

6. "Is the X-ray emission fro the galactic center steady orchanging?"

7. "Is the star Vega moving toward us or away from us?"

8. "Are stars in the Orion Nebula surrounded by dusty disks ofgas?"

------------------------

Introduction: Different telescopes areoptimized for observing different wavelengths of light, so anotherconsideration in planning an observation is deciding what type oftelescope to use.

Part B: Each of the following statementsdescribes an astronomical measurement. Place each measurement intothe appropriate bin based on the type of telescope you would use tomake it.

Three Categories: Infrared Telescope, VisibleLight Telescope and X-Ray Telescope

The Statements:

1. Study a dense cloud of cold gas in space.

2. Measure the brightness of a star that is similar to ourSun.

3. Observe the hot (1-million K) gas in the Sun's corona.

4. Obtain a spectrum of sunlight reflected by Mars.

5. Determine the surface temperature of Venus.

6. Look for high-energy radiation from a supernova.

Thank you so much to whoever helps!

With the question
An oceanographer is studying how the ion concentration in seawaterdepends on depth. She makes a measurement by lowering into thewater a pair of concentric metallic cylinders at the end of a cableand taking data to determine the resistance between theseelectrodes as a function of depth. The water between the twocylinders forms a cylindrical shell of inner radius ra, outerradius rb, and length L much larger than rb. The scientist appliesa potential difference ?V between the inner and outer surfaces,producing an outward radial current I. Let ? represent theresistivity of the water.
We realize that we integrate resistivity(Length/area) but then fromthe solution shown we integrate dR= resistivity(dr/(2pirL)) Weunderstand everything but why the L goes to the bottom of thisintegration.
Thanks.
