Thanks for your help :)

Homework Statement If you have normal vision and are properly using a magnifying glass with a refractive power of 12.5 diopters, how far should you hold it from the object to achieve maximum angular magnification?Homework Equations 1 diopter = 1/focal length = m^-1 M=angular magnification Mmax...

Oh! So the angle doesn't work because the light is not all refracting to the other side at that angle~ some is reflecting. :) Thanks! I still am not exactly sure how to tell if a converging lens will become a diverging one in a different medium...

Homework Statement Can a converging lens in air become a diverging lens in a different refractive medium? Homework Equations n1sin(θ1)=n2sin(θ2) The Attempt at a Solution I was thinking that it would not matter what medium the lens was in, as light would still hit the lens the...

Oohhhh... Thanks! I guess it makes sense that removing a resistor from a parallel circuit does not change the voltage. :)

Homework Statement A circuit consists of 2 resistors, R1 and R2, connected in parallel across a battery. Which statement is false? (A) The greater power is produced in the smaller resistor. (B) If you place another resistor in series with R1 and R2, you will increase the overall...

I'm not sure I understand what you mean by north~ do you mean pointing upwards? The equipotential lines are perpendicular to the electric field lines...

Homework Statement At x = 1.00 m, the voltage is 4.00 V. At x = 3.00 m, the voltage is also 4.00 V. Assuming that there is a steady, uniform non-zero electric field over this entire region, give four possible directions of that electric field. Homework Equations E = (delta V)/d Ue =...

I thought of that too, but the prof said that the samples were all from the same source... good thinking though

Homework Statement We did an experiment in lab today where we were given a compound and we had to figure out the chemical formula and molar mass using titration (titrated with NaOH). The compound I got was phthalic acid, and the average molar mass I got was ~135g. This is about 30 grams off of...

Thank you :)

Homework Statement Name the complex CrCl2(en)2. The oxidation number of chromium is +2 Homework Equations when there are two (en)s, you use bis instead of di because it is bidentate The Attempt at a Solution bis-ethylenediaminedichlorocromide(II)...

Thanks so much :)

Homework Statement What is the coordination number of [Pt(en)3](ClO4)4Homework Equations The Attempt at a Solution I know the method to solve this one, I just have no idea what (en) is and if it is bidentate or polydentate (I've already tried monodentate and it was incorrect). Even the name of...

Thank you both so much! Of course I should have looked at the other rows ~ silly of me. Thanks again :)
