1. ### Movie Magic; Special Effects

I have an assignment on movie magic in which I have to pick a scene from a movie and analyse the physics (including calculations of physics in movie, description and calculations of correct physics etc.) Problem is, I haven't picked a movie yet :frown: I was going to pick 2 different scenes...
2. ### I have a few question concerning Black Boxes

Oh okay I understand :D Thankyou so much for your help!
3. ### I have a few question concerning Black Boxes

Yeah I understood the bit about voltage divided by current = resistance. For some reason i'm having trouble with the bit about it being constant. Does it mean that it will not vary? Can you please give me an example of a constant resistance and a non constant resistance?
4. ### I have a few question concerning Black Boxes

So to stop the 'back voltage' from happening, would I lower the voltage? Sorry, but what do you mean by Voltage and Current being constant?
5. ### I have a few question concerning Black Boxes

Next term for Physics, my teacher has said that he has ordered some black boxes and will be putting a diode, capacitor, resistor and a transistor in each. There is 3 people in my class and he will be making each black box different (he'll put each component between a different terminal)...

Do you mean something along the lines of this ? http://www.absorblearning.com/media/item.action?quick=zy
7. ### Specific Heat Capacity and Specific Latent Heat

Hi Everyone :smile: I have to create an experiment for my assignment in Physics. I've chosen to do something about Specific Heat Capacity. A boy in my class is also doing SHC so I wanted to make mine a little different from his. I've just recently joined physics (never done it before)...
