12 first... since applied force is constant, the torque (F*d) will be proportional to d.... torque for 100mm is 3.. so for 150mm , it will be 4.5Nm... so we have to look for the tensions now..torque is the product of force and moment arm.. and the only force present here is the tension in the belt so 3=F*.1 F=30Nhttp://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w09_qp_12.pdf
i need help here plzzzzzz
in Q no 11,12,13,20,22,25....
frequency = 1/T
and definition of frequency is how many cycles per second and we got 50revolutions per second so i found the time period which is 0.02 so 1 wavelength takes 0.02s to complete so i we use 0.01 we can see half the wave

20.. was so simple yaar... find area under the curve.. ok.. draw a straight line from 0,0 to P... and use 0.5* base * height.. this wil give u 0.1 as answer.. now it is clear that the area you have found is less than the original one but double to it.. so option just little greater than 0.1 isC...http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w09_qp_12.pdf

Oh, alright. Thanks.
And if it's not too much trouble, could you explain question 9 from the same paper? The one about the train.
haan i was confused wd C and B i fnk jo bhi options thay wd 0.1 lolz20.. was so simple yaar... find area under the curve.. ok.. draw a straight line from 0,0 to P... and use 0.5* base * height.. this wil give u 0.1 as answer.. now it is clear that the area you have found is less than the original one but double to it.. so option just little greater than 0.1 isC...
umarashraf thnx lsn i got them all but plz help me wd Q 2 and 37
but shouldnt just da proton number increase????? why is da nucleon nmbr increasing if its beta emission?what what what...??? 37../??? isotopes have same number of protons mate... so D is the answer... whats so special with this one..???
