    Number of oxygen molecules in our lecture theatre

    Heheh I knew it was that simple. It seems I have a bit of mind fuzz, thanks for the kick in the arse!

    Number of oxygen molecules in our lecture theatre

    1. Estimate the number of oxygen molecules in LTD under normal pressure and temperature. 2. I'm guessing you use PV=nRT to get the number of moles of gas in the room and work out the % of oxygen in the air, but I got a number which to me looks too small. 3. Volume of LTD is approx...

    (E&M) Charge and electric field in a two plate system.

    Tall guy with glasses, can't say I've noticed ya... I must be too busy swatting or sleeping in lectures. lol I'm the guy that knocks around with the old git and the ****-knuckle in the halo reach hoodie, also near the back.

    Hahah Yeah I do. Do you happen to have gone there in the past? Coz I've never heard of a tom brown.

    Great. I've got it sussed now. Thanks for the hint my man!

    (E&M) Charge and electric field in a two plate system.

    electric field between the plates: V/D = 250 v/m is that right? for the plates that would be 1000 v/m. you see that's where I started thinking wtf.

    (E&M) Charge and electric field in a two plate system.

    1. Two metal plates, 10 mm thick, are held a distance z=40 mm apart with a potential difference of 10 V across them. As you look at them the positive plate is on the left. In between the plates is a vacuum. Ignoring edge effects and assuming unit area for the plates, calculate both the charge...
