    Have some orange juice before the exam as this helps burning the glucose of your body so that you won't run out of energy

    It's stated to start at 9:00am. So you're pretty early.

    Thanks,
    You're right. I've just seen one of my class mates

    Thought it was good, what was the graph for current supposed to look like? I had the initial current below the first graph but just the same shape which im pretty sure is wrong

    There's no worse feeling than knowing a paper was average in difficulty; but also knowing you have made many small (but still potentially grade changing) mistakes...

    I didn't particularly enjoy that. It was okay, but not the best. I'm still hoping for 120 UMS but it's hard to tell how that went :dontknow:

    What did people put of the damping question? I completely forgot what it was so I tried to work it out there, I put it has no affect?

    Pretty sure it had a lower initial current and then a less steep gradient as time constant was greater?!

    I thought the same; but was told by my peers that the current had the same start point.

    Little questions:
    Gravitational potential is a vector isn't it?
    I put the oscillations were less damped with the metal ring - thoughts on this? I reasoned the air resistance force would be constant but as F=ma, the pendulum would deccelerate more slowly so would be less damped.

    It has no effect from the equation of time period of a simple pendulum (at least i think?)

    Why would it? If you simplify it and treat it like a battery for the same voltage but huger resistance it would have a lower current, why wouldn't that hold for a capacitor?

    There's more damping without the ring because the ring increases the pendulum's weight and the resistance's effect will be decreased.
