"Within 1 standard Deviation of mean" mtlb :/
It means that the data deviates +1 and -1 of mean
Not +1 -1 but +1 -1 of the STANDARD DEVIATION. if mean is 9 and sd is 2 then our range os 7-11 not 8-10
can u plz solve that question part ii only
Thanks! but how do you know that the tension in the strings is equal to the weight of A and B respectively?There you go, if you have any more doubts just tell me

First get the equations of z*w and z/w in a+bi form and then just plot the "a" on the real axis and "b" on the imaginary axis if you have trouble getting the z*w or the z/w in a a+bi from for a question let me know i might be able to help you out
Oh ok! That's amazing, I get it now, thank you
You mean A and C? It says the whole system is in equilibrium , so for A and C to stay in equilibrium , the tension in the strings they are attached to must be equal to their weights respectively, thus first string has a tension of 5.5 N and the other string has a tension of W N
W=6N
Work done by engine is the same as work done by driving force. The driving force is provided by the engine.
Please can you draw me the diagram??
