Document Summary

4 essay questions (1 question per part), 25% each. Estimate about a booklet per question, double spaced! May be a question about create dialogue between thinkers. Believe born from good and society turns us bad. Society functions between when women take care of men. Optimist view of human nature, but not society. Care, drivers, hidden in subconscious, therefore cannot know self. Relation to environment is how population increases or decreases. Natural instinct to improve quality of life for self and others. People will always come over obstacles to equal society. Socio biology [social behavior determined by biology] to behaviorism [study of behavior] To be conscious, know, aware of something is to perceive it. Can only know things that we perceive through the senses. Only conscious of something when at that moment perceiving it. Christian conception of human nature compare with darwin and nietzsche. Man is created in the image of god.

This question has been asked before, but I don't believe theanswer was entirely correct. Really think about number 1 with B andhow e would be affected.

A parallel plate capacitor was connected to a DC Battery andCharged. The separation between the plates was then increased by afactor of two. Apply the following scenarios:

1.) Before the separation was Increased the Capacitor wasdisconnected from the battery.

2.) The Capacitor remained connected to theBattery while the separation was Increased.

For both scenarios show How the following quantitiesChanged..
a.) Capacitance?
b.) Charge on the Capacitor?
c.) Potential Difference between the Plates?
d.) Electric Field between the Plates?
e.) Energy Accumulated in the Capacitor..In particular has therebeen work done to move the platesand has there been energy drawn from the battery or did thebattery receive energy from the work done onseparating the plates?

How fast can a racecar travel through a circular tum without skidding and hitting the wall? The answer could depend on several factors:

The weight of the car;
The friction between the tires and the road;
The radius of the circle;
The “steepness” of the turn.

In this project, we investigate this question for NASCAR racecars at the Bristol Motor Speedway in Tennessee. Before considering this track in particular, we use vector functions to develop the mathematics and physics necessary for answering questions such as this.

A car of mass m moves with constant angular speed to around a circular curve of radius R (Figure 3.20). The curve is banked at an angle . If the height of the car off the ground is h, then the position of the car at time t is given by the function

As the car moves around the curve, three forces act on it: gravity, the force exerted by the road (this force is perpendicular to the ground), and the friction force (Figure 3.21). Because describing the frictional force generated by the tires and the road is complex, we use a standard approximation for the frictional force. Assume that for some positive constant . The constant is called the coefficient of friction.

Let denote the maximum speed the car can attain through the curve without skidding. In other words, is the fastest speed at which the car can navigate the turn. When the car is navigate at this speed, the magnitude of the centripetal force is

The next three questions deal with developing a formula that relates the speed to the banking angle .

Now that we have a formula relating the maximum speed of the car and the banking angle, we are in a position to answer the questions like the one posed at the beginning of the project.

The Bristol Motor Speedway is a NASCAR short track in Bristol, Tennessee. The track has the approximate shape shown in Figure 3.22. Each end of the track is approximately semicircular, so when cars make turns they are traveling along an approximately circular curve. If a car takes the inside track and speeds along the bottom of turn 1, the car travels along a semicircle of radius approximately with a banking angle of . If the car decides to take the outside track and speeds along the top of turn 1, then the car travels along a semicircle with a banking angle of . (The track has variable angle banking.)

The coefficient of friction for a normal fire in Elly conditions is approximately . Therefore, we assume the coefficient for a NASCAR tire in dry conditions is approximately .

Before answering the following questions, note that it is easier to do computations in terms of feet and seconds, and then convert the answers to miles per hour as a final step.

11. Suppose the measured speed of a car going along the outside edge of the turn is . Estimate the coefficient of friction for the car’s tires.

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?
