You are so right! Thank you!

I'm trying to write an address book that is based on a binary tree. I'm devloping in Visual C++ (I blew up my Ubuntu with the new dist), starting with the basics: #ifndef binarySearchTree_h #define binarySearchTree_h #include <string> #include <iostream> using namespace std...

hahhaahaha, I got it... I needed to fix my area. S/B (4 cm / 2)(10 cm / 2) = 10 cm... got my answer, thanks anyway

HELP! Induced Voltage question Here it is: Coil has 10 turns and shaped in an elipse (A = pie ab), having a major axis of 10 cm (10 X 10^-2 m) and minor axis 4 cm (4 X 10^-2m). Coil rotates 100 rpm in a region in which the magnitude of the Earth's magnetic field is 55 microT. What is max...

First you should review what to do with resisters in a series or parallel. If in a series do you add them or do you add the inverse? There should be something in your book that mentions what to do.

In this lab, I'm supposed to find the average slope between a charging and discharging capacitor. For the slope of charging and for the slope discharging I used the basic formula y2-y1/x2-x1 choosing arbritary points on both lines. Charging slope = 4.6/-15, and discharging slope = 3.48/-57. Now...

well said, Warren. The connections were alligator clips and this board that you shove the wires in. Very, well, rinki dink, or something. All of our labs have been poorly done like this. One group out of the 4 was able to get the experiment to work correctly. I intend to use their data (the...

Hopefully this schematic I have attached will help you see the circuit we made. Our capacitor was attached to a 'board' and the whole circuit was ok'd by our instructor. The R (of course ) stands for resistor. The first C1 = 1000 microF The first R1 = 10 kOhms The 2nd C2 = 2200 microF...

OK, here is my frustration: I go to my lab, exchange equipment several times because some equipment is bad or wrong, do an experiment to show the time constant. First we charge the capacitor. Trial and error to find a good time increment. THEN, its time to discharge. AFTER 10 minutes of the...

THANK YOU... I got it. SO MUCH HELP! thank you thank you thank you

Here is the problem: A singly charged positive ion has a mass of 2.50 X 10 ^-26 kg. After being accelerated through a potential difference of 250 V, the ion enters a magnetic field of 0.500 T, in a direction perpendicular to the field. Calculate the radius of the path of the ion in the field...

Wow. Thank you, that is most helpful. The link is terrific. Again, thank you!

You are awesome! Thank you! :approve:

I'm going through my book and one of the Example exercises has the following problem: Two plates, each of area 3X10^-4 m^2 are used to construc a parallel-plate capacitor with capacitance 1 pF. (a) Find the necessary separation distance. Seems pretty obvious right? C = Eo(A/d) So, I...

Unfortunately, the book says that 24nC is the answer. Its been wrong before, but not very often. and about the nC, I was thinking it was Newton per Couloumb. Didn't even consider a nano couloumb... I will run with that. Thankyou
