Thanks, that's what I wanted to confirm. Thanks Khan Academy...

Homework Statement [/B] How many distinct stereoisomers exist for the hexadecanoic acid and oleic acid, respectively? Please choose from one of the following options. 1, 1 1, 2 2, 2 2, 4 Homework Equations None The Attempt at a Solution If you look at the following images of hexadecanoic...

I ended up getting it. You solved for C first by defining dA as 2*pi*r*dr... that was the part I couldn't get.

Homework Statement Find an expression for the magnetic field inside a wire carrying a current density J = Cr2 where C is a constant to be determined in the problem. The total current in the wire is I and the radius of the wire is R. Your answer should be a function of r, R and I, but should not...

Figured it out, thanks!

urgent Diff. Eqs. Wronskian question Homework Statement See attached image- it's a lot easier. Homework Equations We know that when the wronskina = 0, it is linearly dependent on most points, and if it is not equal to 0, then the solutions form a fundamental set of solutions because...

Homework Statement ((1/3)(y^3))+(1/y)=.5*ln((x^2)+1) Solve in terms of y Homework Equations The Attempt at a Solution I am in college differential equations, and i just can't solve in terms of y. y teacher wants that...i tried wolfram alpha, etc. How on Earth do you factor this...

Technically I know that A= .5(m2)∏...but I can't write that like I can dA/dt I can write V in terms of m -> V=∏m3,and get an equation for dV/dm...does this help?

Homework Statement A circular cone (height H = 2m, radius of the top R = 1m) with a vertical axis and the vertex pointing down is filled with water. At t = 0 a small circular hole is opened at the vertex. By Torricelli's law, the rate of change of the volume V = V (t) of water in the...

Sorry, didn't attach the first time

URGENT: Delta-Wye transformations Hello there. In my electrical fundamentals class (a 201 level class), we just barely started Delta-Wye transformations. However, the homework that is due online tonight uses full transformations...confused, I have just tried to work through this using the book...

Homework Statement A gaseous mixture containing 0.190 mol fraction of carbon tetrachloride (CCl4) and 0.810 mol fraction of dry air is initially at 62.0°C and 1141 mmHg. If this mixture is cooled at a constant pressure, at what temperature does the CCl4 first start to condense? I already did...

Inferometer problem: URGENT After trying to do this problem all night the night before it was due, and no avail on just scouring the internet, I would really appreciate some quick help if anyone is still up. (Or early in the morning) Homework Statement Optical computers require microscopic...

Thank you! I understand a bit better now.

I thought you used d and L-d because that was the length over which you were integrating. It's always just over the total length?
