any1 wants 2 discuss abt physics p31??
Ykov:
Which paper is this? :O I'm doing the paper where the 1st question involved a semi-conductor diode and the 2nd question involved measuring the velocity of a ball through an oil medium

Sorry my bad. I took a different paper :D .
The first question had 12 resistors and a power source. The second involved oscillations of two hollow tubes.
For anyone who wants to discuss it with me, I took paper 31 :) .
Ykov:
Oh, thank God XD
That question seems hard though. Ours just basically asked us to connect a circuit with a diode, a voltmeter and ammeter. Then we just adjust the power supply and read off the voltmeter and ammeter. :-X

By the way, the L cannot be negative since that there was a plus sign before it !!
I got the gradient as 3.53 "AOhm" and the y-intercept as 0.0034 A.

got a similar gradient like urs mine was 3.66Aohm and my y intercept was 0.0043A
neno:
wat abt the values of the tube lengths....1st one was 5.71cm and the 2nd was 24.8cm
and both my k vr different so tht equation doesnt show the relation ryt
