Some examples of (basic) trigonometry in physics could be: Force resolutes - FgCos(Theta) Addition of Sine waves - Sine(X+Y), used in electronics Oscillations etc There's much, much more than that, but that's some applicable examples for you.

I'm currently studying complex numbers in my high maths class, moving onto trigonometry. I already know some applications of complex numbers, such as phase differences in capacitive and inductive circuits, but what other applications are there? Can they be applied to circular motion in...

In Thailand I had a bag full of fried crickets, cockroaches and other bugs. And I'm still alive. In fact, it was very tasty.

From a fiscal point of view:running cost, maintenance cost (replacing cells etc..) and initial cost is obviously the optimum values to try and minimize. That being said, You will need to investigate the optimum way to set up, run and maintain the solar cells, with a respect to cost. This could...

What he meant was that: you're using the wrong method for the problem. Although, He might have interpreted it as though you wanted to build the oscillator solely using IC's. Basically, I'd say that you'd need the 555 to start the oscillator circuit at a specified time, t, wherein it just runs...

What I mean is, theories/basics of chemistry without the lab work (so it's just theoretical, not experimental or practical).

He should just use the water displacement method, and not take it out.

Any suggestions for theoretical chemistry , though?

And what type of topics have you previously studied? I'd suggest going over past material, your physics textbook, some outside reading, maybe a few wikipedia articles and reading other textbooks.

It was merely a suggestion, rather than a definite answer. Since, I was just going to give an idea but not a solution. I can see how it is irrelevant now, but my original post was just to give a suggestion which may help. The OP's post has been solved, though. So this conversation is no...

True, but we are not given the frequency of current, diameter or gauge of wire or material of wire, so I can only suggest the skin effect without any other information. Then again, there will be cooling effects of the posts and such.

Well, what do you plan to do for a career? What are your aspirations?

Does that mean that, during phase change the energy will be a constant amount, or will it still change with change in specific heat capacity (as I thought it was)?

The specific heat formula is indeed, mc\DeltaT, where m=mass, c=specific heat capacity and \DeltaT= change in temperature. You'll need to find what energy is required in each transformation, from ice->water then water->steam, using the different specific heat capacities. The answer should be...

I think you'll need to investigate something called "the skin effect".
