Document Summary

Lecture 7 (wednesday october 20th, 2010) chapter 6 continues: begging the question raises the question, tends to support the conclusion with the conclusion. In hamlet polonius says he"s mad, i tell you. Mad , this is begging the question: raises the question hides the repetition by changing the words, example on pg 164, hides the repletion by assuming the conclusion in the argument. C. impossible for all to be well known. C. we should believe god exists: hide the repetition in a refutation of a counter consideration. Bible says in genesis that world created in six days. Ussher shows that the bible also gives 6000 as age. Carbon dating and other methods show world to be older. Impossible for anything to be older than 6000 years. C. world created in six days, six thousand years ago: example on pg 171. Premise is we have the right to do whatever it takes to maximize profits for shareholders .

I got the conceptual part but not the question chapter 18question10

A charge of +q is located atthe origin, while an identicalcharge is located on the xaxis at x = 0.43 m. Athirdcharge of +3q is located on the x axisatsuch a place that the net electrostatic force on the charge attheorigin triples, its directionremaining unchanged. Where shouldthe third charge be located?

Particles of mud are thrown from the rim of a rolling wheel. Ifthe forward speed of the wheel is v₀,and the radius of the wheel is b, show that the greatest heightabove teh ground that the mud can go is

b+(vo^2)/(2g)+(gb^2)/(2vo^2)

at what point on the rolling wheel does this mud leave?

(note: It is necessary to assume that vo^2 â¥ bg.)

This is a question from the book "Analytical Mechanics" seventhedition by fowles and cassiday. chapter 4 problem 7. cramster "has"the solution worked out but two problems. 1) it's wrong and 2) itis damn near impossible for me to follow.

The person doing the problem just pulls random equations out touse without saying why. If i knew why they were being used thatwould basically solve most of my problems about the question. Alsothe few discriptions the problem has seems to have very badgrammar/punctuation and so trying to follow it is nearimpossible.

So any work through of the problem would be great. But more ofwhat I'm looking for is what should be going through one's mindwhen proceeding with the problem? What equations should be used andWHY?

Oscilloscope trigger problem. The 'trigger' settings determinewhenthe trace begins. Suppose you have displayed a sine wave with V=Vosin(Ït) on the screen, where Vo=4Vand Ï/2Ï=5kHz. Assume furtherthat thesignal triggers the scope when V=2V andÏt=30 degrees.
EXAMPLE:
Suppose you double the amplitude of the wave without changinganyoscilloscope settings. What are V andÏt now when the scope istriggered? [Answer: thelevel hasn't changed so the scope stilltriggers whenV=2V.V=2=8sin(Ït); Ït=sinâ1(2/8)=14.4775121851511degrees.]
QUESTION:
Assume that you reduce Vo back to 4 V and switch thetrigger slopepolarity from '+' to '-' without changing the triggerlevel dial.What are V and Ït when the scope is triggerednow?
Volts,
degrees
