thanks but nvm about that. what about THIS QUESTION?its kind of a common sense type of question it cant be D at all beacuse its exceeding the limit cant be C because it cant stay the same and cant be A because it cant go that low so its B, thats what i think
Because we are working with the same volume of that conducting putty, an increase in c.s.a will bring a decrease in the length by the same factor as the c.s.a ( Volume of cylinder=pie r square * length/height)
I am guessing I am late but still...I need help real quick.. ..
it's 0625_s10_qp_32 question number 9 section b (i)
why is the resistance 2 ohm but not 6/11??
shouldn't the circuit be a parallel ? please hellllp
Call the tensions in the two wires A and B newtons respectively. Take moments about one of the points where the wire is attached to the beam. If this is where the A force acts, then its moment will be zero and you can apply the principle of moments to find B. Once you have B you can simply use the fact that the total upward force is equal to the total downward force. In this case A + B = 9g newtons. Job done.Physics Problem...
A uniform metal tube of length 5m and mass 9kg is suspended horizontally by two vertical wires attached at 50 cm and 150 cm respectively from the ends of the tube. Find the tension in each wire.
Hope you can help ^-^
