    Physics, Chemistry and Biology: Post your doubts here!

    Oh god you genius -.- I now need to spend the rest of time understanding this.. Thanks alot though, really helpful stuff x) -EDIT- Wait, if theres alot of waves squashed up, why would we increase the time base? Suppose there are 10 waves being shown in 1 second.. and we increase the time base...

    I think its distance between 2 peaks, Im terrible at that time base setting/peak stuff.

    Physics, Chemistry and Biology: Post your doubts here!

    You asked this before , and I answered. Maybe you didn't see it , so I'll just copy/paste it. Here: For c) Use the equation for power, but you'll have to change it a bit. Power = energy /time Energy = power*time Energy = current*voltage*time Energy = current^2*resistance*time NOW you can...

    Physics, Chemistry and Biology: Post your doubts here!

    There really EASY. For AND gates, just remember the word "AND" .. so it means that inputs A "AND" B should be high for an high output. NAND gates are the opposite of "AND" gates. OR gates , just remember the word "OR" .. meaning input A "OR" B should be high for an high output. NOR gates are...

    Yeah, the slight chance that they do end up asking a question about those.. its usually worth alot of marks :S

    Scalar quantities are quantities WITHOUT a DIRECTION, such as speed. Vector quantities are quantities WITH a DIRECTION, such as velocity. Renewable sources of energy are anything besides fossil fuels such as tidal, wind, hydro-electric, etc. Non-renewable sources of energy are those that are...

    How do you check exact percentages for your IGCSE marks ?

    Good question, I'd like to see a reply to this. I think it's only grades though and the percentage of THAT grade written next to it. For example , if you get an A it would be written 80% . That's what I think :S

    Basically this is what it should look like, only reflect ONCE! (Once again my paint skills prevail)

    Physics, Chemistry and Biology: Post your doubts here!

    NEITHER! Remember the mark scheme? It said only ONE reflection, if its more then one they will cut a mark, if it's more then two then you get 0. It's only one reflection.. I'll try to make a diagram :S
