PICTURE INCLUDED 1. Homework Statement A piece of wire is bent into an isosceles right triangle whose shorter sides have length a The wire carries current I. Calculate the magnetic field for point P. Point P is located on the Y-axis ( 0, √2a). Two corners of the triangle are are located at...

Homework Statement After diluting 20.00mL of vinegar sample to 500.0 mL in a volumetric flask, a student titrated a 20.00 mL aliquot of this diluted solution against a 0.1120 M NaOH solution. The acetic acid requires 27.98 mL of base. What is the % HC2H3O2 in vinegar? Homework Equations M1V1 =...

Wow. Thanks a a lot. Now it makes way more sense for that cycle.

Well I think it's huge because it would mean that I can trust my g only to 3 sig figs. So I pretty much throw away one sig fig.

Here, I figured it out.

Here is picture of the equation and detail calculations. * I don't know how to rotate the picture, sorry. Edit: Image rotated by moderator:

Thanks! Makes it more convenient.

Homework Statement I have to calculate the propagated error on g of pendulum. I pretty much measured the T of pendulum and now calculating g while increasing the number of cycles. Homework Equations I used the equation of propagated error and i included picture of it and my calculations. The...

So when it says that oxygen is combining it should be just O, not O2. If i understood correctly.

A sample of sulfur having a mass of 1.28 g combines with oxygen to form a compound with a mass of 3.2g. What is the empirical formula. So what i did is found the mass of oxygen which is 1.92g . Then converted the 1.28g S to 0.04 mol. Then converted the 1.92g O2 (as it says oxygen, or should it...

ok, great. Thanks

It seems like a long way from solving for (x/2) by cos, and then substituting cos, just to get (x/2).

So I saw the cow tipping problem and I am having trouble figuring out how they got to the final equation. Imagine making a rectangle around a cows body. Making a diagonal across the rectangle and center of mass being in center of the diagonal. One half of the diagonal is "a", and second is "b"...

This sound exactly right. So, if you know the solubility then you can determine if it's aq, right?

Does anybody know where I could find worksheet to practice naming the state of matter in chemical reactions (with answers in the worksheet to check) as I have problems with that. Especially deciding when it is aqueous. I know (well at least i am right) that when you have acid as reactants it has...
