    Sorry i typed out only half my reply....before posting by accident When alpha was fired at gold foil most of the particles went undeviated through the foil and only 1 in 10000 were deflected by a large angle. This led to the conclusion that the mass of an atom is concentrated in a tiny volume...

    Its quite simple.. Without the magnetic field both beta and gamma would be detected. When the field is introduced beta gets deflected by a very large angle because of it's charge and very negligible mass. Therefore gamma passes undevited and reaches the detector so yes 1950 is only for gamma...

    Since reaction takes place at room temp then reacting mole ratio is equal to reacting volume ratio so all the gas gets used up and true is nothing remaining.Hence A is the ans

    Wow..never thought abt that. Thanks a lot bro!! How were the exams upto now? Bio 22 and lit papers were horrible....Well at least the most dreaded part of the ols are over now!

    Ans to that is A since X forms X3- and Y would be Y- so cross the charges you get XY3

    Hi Can anyone explain to me the logic of part iv of the question. The ms has given a confusing answer....

    Biology; Chemistry; Physics: Post your doubts here!

    Just checked the ms... c) sensible suggestion, e.g. use marker to fix drop height/repeats and average hold/drop in the same way/use stopwatch Its just a one mark q so sayeng repeat and average will give you the mark.lol:):ROFLMAO: Yeah,i agree....but i think both are correct as long as its...

    Awesome12 The issue of reaction time,late starting,early stopping and all the stuff exist when two people are used since both of them have different reaction times. The best would be to drop it from a known height(shoulder level perhaps) and manipulate the stopwatch in your other hand. Reapeat...
