Thats the results I got, thank you =D

Maths
The question is "Show that z-2 is a factor of P(z)= z^3+mz^2+(3m-2)z-10m-4 for all values of m. For what values of m is (z-2)^2 a factor of P(z)?" I've proven the first part, using synthetic division, for all values of m. But the second part, I don't understa...

Chemistry
I just did an experiment on the enthalpy of combustion of different alcohols, and for my report, I've written that the condition of the wick is a source of random error, but i can't seem to explain it. I've written that it affects the rate of burning of the flame, ...

Maths - Matrices
I'm having trouble with doing this matrix proof The question is "Given some matrix A has the property A*2=A^-1, show that determinant A = 1, i.e |A| = 1" I've tried for ages, but I can't seem to do it, this is what I got to A^2= A^-1 |A^2| = |A^-1| |A|^2 ...

I'm writing a prac report, and I just need something clarified. The experiment was different masses were attached on a hanging spring, then it had to be pulled down a certain distance, then find the period by finding the time fo each oscillation for each mass. The problem ...

Thanks

I'm writing a prac report on an experiment where we had to vary the mass on a spring, and graph it against the period, then graph it again when period vs square root of mass, which should be linear given the proportionality. Does it really matter which unit i use? g or kg
