could anyone tell me some uses of alpha.beta and gamma rays?
thanks.
i dunno them seperately but here are sum uses for radiations
smoke detectors
thickness gauge
checking leakage in pipes
carbon dating
treatment of cancer
detecting faulty welds

could some 1 help me with
june03 paper no3___________Q3a and   @11 a and b


use a scale 100N=1cm. draw a line 12.2cm starting at the left hand pin on the bar parallel to the 1220N force, and a line 9.5 cm staring at the right hand pin parallel to th 950N force. Where these to lines meet draw a diangonal to the opposite corner of the paralllelogram. Timnes this length by 100 to get the force in N.

11a)Use aluminium or lead sheets between the source and a detector. Nothing is detected therefore an alpha emittor

b)Use the left hand rule. Deflected into paper

I hav some quests in ppr may june 2002
 2c)
8c)
and in may june 2007
2a) and 9a)
and i need explanation i hav the markin scheme but i need to understnad it
thnk u  ;)


2c: the change in speed is 9.5 m/s cause frm 9.5,when the ball touches the grnd it comes to 0 so its 9.5 i hope thats what the mark scheme says

8c: the function of a diode is that its a rectified, it changes frm A.C to D.C so as the A.C current flows in forward bias of the diode, the diode allows the flow but when A.C flows in the opposite direction, the diode doesn't allow that so A.C changes to D.C

n for 2007 i don't hav the paper so if u give me the question, ill clear it

all the best
Thanks but sry to burst ur bubble but the answer in the markin scheme is 1.5 n 17.5 m/s  :-\
n sry i neede to ask 9c) not 8c)
n neva mind for 2007 they r all daigrams
Thanks alot aneways :)


lol sorry fer the incorrect answers well then the other alternative is first one is 9.5 - 8 and the second one is 9.5 + 8 :D
well it does make sense change in speed at that point is 1.5 n change in velocity is 17.5 sorry fer the wrong answer :)
