Re: Shock Value B/Circuit Lab C

Just a question before my state competition :P http://www.princeton.edu/~aqu/Scioly/products/Scioly%20Practicetests/2006_PA_south_regional/exam.pdf I was looking at problem 8 in section 2, where it asks which range the voltmeter should be set on. I always thought ideal voltmeters had infinite resist...

Re: Technical Problem Solving C

Yeah, probably. Tons TPS event supervisors stretch the rules pretty often anyways so I guess it's a moot point.

Re: Technical Problem Solving C

Caltech students made the tests...so ridiculous is all part of it. They gave you the pyruvate and OAA molecular structure and expected you to determine what amino acids are formed when they bind to aminotransferase. Points were given for both the correct molecular structure and the name of the amin...

Pretty obscure and there's no way you'd get close to the answer without knowing it off the top of your head, which makes for a bad fermi question imo

Re: Technical Problem Solving C

If anyone has already competed in this event for states, I (and many others) would greatly appreciate it if you gave an overview of the test, the labs that you had to do, etc. The main problem for our team is the usage of probes, since my school is too poor to afford them. (The lab portion was also...

Re: Astronomy C

As far as I know, He shell burning occurs on the AGB (source: C/O, p. 458-459, 463 - if the page numbers don't match up between editions, it's Fig 13.4, 13.5, and the section entitled "The Early Asymptotic Giant Branch"). You may have mixed it up with hydrogen shell burning, which does in...

Re: Astronomy C

Quick Question: For question 73 in the 2012 PA Regionals test the question asks when helium shell burning takes place. I thought this occurred during the subgiant branch but the answer key says it occurs in the AGB. Carrol and Ostile seems to support my choice, is the answer key just wrong or am I b...

Re: Shock Value B/Circuit Lab C

Oops, I meant "multilooped. It autocorrected it 0.o As in, circuits with multiple batteries. Can someone explain why the loop and current directions when using kirkhoffe's rules are arbitrary? Because if you choose the direction to be wrong, you'll simply end up with a negative current. Howeve...

Re: Pennsylvania 2013

For anyone doing Astro. Based on the state tests from last year and the year before, it looks like A LOT of the info is taken from Carrol and Ostile's Introduction to Modern Astrophysics. Sometimes verbatim (like the H-R Diagram of the evo of a 5 solar mass star and a bunch of stuff from questions 9...
