I just have a quick question, and if anyone could help, I would really appreciate it. Two lightbulbs, one rated 30 W at 120 V and one rated 40 W at 120 V, are arranged in two different circuits (parallel and series). The power source of both circuits is 120 V. What would the order of the...

Hi, I've been working on a review assignment for a while, and I"m very good at electricity, so this question has me stumped. Specifically, the 2002 AP Physics B, #3. Two lightbulbs, one rated 30 W at 120 V and another rated 40 W at 120 V, are arranged in two different circuits. (a) The...

Can you prepare for AP exams by study guides alone? For example can you prepare for AP biology from a PrincetonReview and Cliffs study guide? What's the best way to learn in less time, and still get a 5? PLEASE! I would like only encouraging remarks. Thank you,.

OK, In high school, I'll be taking math up till AP Calculus BC, and in University, I'll be going in sciences, and will need a lot of math. I'm planning to buy a TI-89 Titanium. I want one, widely used, and will easily fulfill all my needs. Is this a good choice?

I am currently struggling in AP Physics B at school and find the textbook issued to me by the school (College Physics by Serway and Faughn Fifth Edition) a bit difficult to comprehend. I do not want to fail the class or the AP test and was wondering if there were any good, easy to understand AP...

I'm not sure of whether or not I should waste 150 dollars to buy one of the most powerful calculators released by TI, the Ti-89 titanium. For all of you who own one or knows someone who does, how is it?? Right now I have a Ti-84, but I don't think it is as efficient as a Ti-89.. And yes, Ti-89s...

A flywheel of mass 42.7 kg is supported by an axle 1.65 m long, with two small wheels. The axle's wheels roll on an elevated track, part of which has a curve of radius, R = 15.9 m. If the flywheel has angular momentum 75.50 kg·m2/s, what is the maximum speed at which the system can take the...

Can anyone help me with problem 2 on the 2002 free response section for mechanics: The cart is mass m and has four solid rubber tires each of mass m/4 and radius r. Each tire has rotational inertia ½ ML2. The cart is released from rest and rolls without slipping from the top of an inclined...

No one in my AP Bio class has an A. Not a single person. The highest we've gotten yet is an 86%, and that's from the girl who studies three hours every day. Is this normal? We're nearing the end of the semester, and yet most of the class has Cs and Ds. It's the teacher's first year teaching AP...

Here is the actual physics problem. Below it I will try to explain exactly how I thought to figure it out. I would appreciate it if you corrected me If I made any errors. I am very sketchy on this one after being out for a week from class. http://img74.imageshack.us/img74/2937/img012brz6.th.jpg...

Okay, so I was browsing through an AP chemistry book because I really want to major in either chemistry of physics and want to take advantage over thanksgiving break to get ahead on chemistry because I really love it ^^. So I was wondering if someone could check my work on this problem. Thanks...

A small block of mass m is on a horizontal frictionless surface as it travels around the inside of a hoop of radius R. The coefficient of friction between the block and the wall is mu; therefore, the speed v of the block decreases. In terms of m, R, mu, and v, find expressions for: a. the...

I have managed to get the worst teacher in the world for my AP Physics class. I was wondering how to do this problem: How much tension must a rope withstand if it is used to accelerate a 1400 kg car vertically upward at 0.70 m/s2? I really have no idea how to start it...:redface: But hopefully...

I'll try not to rant too much--but I am sure most of you have heard of "Advanced Placement" courses and exams? Yes... Well ever since I first took physics as a 9th grade student, I became enthralled and realized I might want to major in it someday...well I thought I might take the AP course...

Completed Honor Biology in June and doing Chemistry in summer school. Can do only one science class in the fall. AP Biology or AP Chemistry this fall, which one? Thanks for your help.

Next semester, I will have the option of taking Calculus AB (AP) or Calculus 1 at a local community college. From what I heard, Calculus AB only covers topics in Calculus 1. I also heard that college courses are superior to AP courses and they are better preparation for future college...

Does anyone know a good site and/or book on ap physics? I'm taking it next year (senior year high shcool...) and i wanted to see what new material we'd be covering and maybe do a little reading. Thanks in Advance

Hello fellow scienteers and mathematians :p, after talking with my computer science teacher (who I idolize ;)) I've decided to take AP Physics next year, he'd be my teacher for that course. He wouldn't tell me what I'd be taught in that course, figures, since he's a teacher and all that jazz...

Right now I'm reviewing old AP problems for the AP exam for Physics B tomorrow, and I can't seem to get a simple spring problem. I don't know why, but I can't just grasp it. Here it is: A block of mass 3kg is hung from a spring, causing it to stretch 12 cm at equilibrium, as shown above...

did anyone take the ap calc bc exam this morning? how did everyone do?

I have some questions (or checks) on some problems from a fatty packet our teacher decided to give us for the AP test. If I've already given a possible solution, see if I did it right. Thanks! Problem 1: A simple pendulum consists of a mass 1.8kg attached to a string of length 2.3m...

The following remarks were written by me to my sons' high school community some years ago. I believe they are still relevant. They were then considered so heretical that they were not acceptable as publishable. The idea of posting these remarks was inspired by Zapper Z's extensive and...

Recently my AP Physics class had a test on energy. The following is one of the questions verbatim from the test. I just can't work out the problem to any of the choices, let alone the "correct" choice. The problem is: Movers want to set the ramp of their truck so that the work they do against...

If dy/dx = 2y^2 and if y=-1 when x=1 then when x=2, y=? I have no idea how to even start this probelm, i never seen this on any previous practice tests i thought about using the equation y+1 = dy/dx (x-1), but that's probably wrong and not going to help...

Two 10-kilogram boxes are connected by a massless string that passes over a massless frictionless pulley. The bxes remain at rest, with one on the right hanging vertically and the one n the left 2.0 meters from the bottom of an inclined plane that makes an angle of 60 degrees with the...
