Thanks a lot for your help :) I really appreciate it!

While I did as you said, gneill, I couldn't ascertain which was the right one - the 'd' part or the LHS.

The experiment isn't very important per-se, but for the record, there are two stand clamps, with a wire attached to both, forming a triangle. At the bottom, there's a pendulum, and d is the distance between the two stands. So yeah, definitely in meters. It's also given, but because of copyright...

That should be a pi :) I couldn't find the symbol :P

Well, after working it out, the left side is this: T4 has units s4. For the K part, I can't work it out without knowing whether it's homogeneous or not. So I go where there's d. (8d∏4)/g2 would then become: Numerator: m Denominator: m2.s-4 Therefore this part would be s4.m-1 For...

So you confirm the equation is not homogeneous?

1. So for today's exam, I was given this equation, and I was required to get the value and units of K: T4 = (4K∏4)/g2 - (8d∏4)/g2 I had to follow an experiment, plot the results, get the gradient. After getting the value of g, I was required to find the value of K, and its units. T4 has...

So the charge doesn't change between the two parts? Hence I can use Q/C = V? If yes, then the voltage is 3.44V. Also, sorry about the units. I had been going at this question for an hour, and I was extremely frustrated. Thanks a lot guys! I really appreciate your help!

1. One question I'm having a lot of trouble solving is this: The plates of a parallel plate air capacitor have an area of 100cm2. The capacitor has a capacitance of 3.5nF and is connected to a 12V battery. It is fully charged. Calculate the: a) separation of the plates b) magnitude of...

Thanks, didn't notice the hyperlink in the first reply :)

Thanks a lot for your answer :) Yeah, sorry - I forgot the units. What should I do with the number of turns of the wire?

1. A flat rectangular coil measuring 2cm x 3cm and having 60 tuns of wire is turned through 90 degrees in 0.2s. The flux density of the magnetic field is 0.30T. Please note that a diagram is also provided - basically the coil is first perpendicular to the field, then it's rotated so as to become...
