Mathematics: Post your doubts here!
Yeah you can say so, more like on an educated guess though :P -
Mathematics: Post your doubts here!
Weight is a random variable and that too a continuous one. The distribution for a continuous random variable is 'normal distribution' (according to what we have studied) with parameters (Mean, variance)........ Just put in some sensible appropriate values for an average of weight of 18 year old... -

PHYSICS M/J/9702 2017 Paper 41
I said kinetic energy = qV And since v=p/m, KE = p^2/2m and then I just rearranged the whole thing -

Hehe :cool: I didnt really get the chance to talk to many people but everyone I talked to were confused. For them, it was somewhere in the middle, not too good not too bad :D It was like it's either all right or either all wrong :) -

Was it really that hard? I didn't find it that hard :whistle: -
Physics: Post your doubts here!
Use the fact that <c^2> is directly proportional to the kelvin temperature Cross multiply: 1.9 x 10^6 ------------> (32+273) ? -------------> (80+273) Once you get the mean square speed at 80 (that is, '?'), square root it to get root mean square speed -
Physics: Post your doubts here!
They have already provided you with the electric field strength and the charge and are asking you what the additional charge should be to have the electric field strength as 2x10^6 We know that E=kq/(r^2) so we can use the given information to get a value for k/(r^2) since these values will... -

It's always connected in parallel :) -
XPC BEST MEMORY
haha yeah I got that, I didn't get that YOU were the fish :P -
XPC BEST MEMORY
Okay I confess that I did not get that (the thing about you being the fish) :P and I did get a bit confused at your cheering st first but then I was like, meh, it's probably a figure of speech and yeah you just added a yaaaaaaaayyy :D :cool: Haha, that's very reassuring to be honest <3
