Both diamond and graphite are made of carbon. Carbon can form a maximum of 4 covalent bonds due to carbon having 4 electrons on it's outer shell. In diamond, each carbon atom forms 4 covalent bonds in a tetr...

Speed is a scalar quantity, meaning that it only has a magnitude. Acceleration is a vector quantity, meaning that it has a magnitude and a direction. Velocity is the vector quantity equivalent of speed, as i...

we can use the subtraction method to find this out: create a table set out like this 2 7 | 2 6 | 2 5 | 2 4 | 2 3 | 2 2 | 2 1 | 2 0 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 | | | | | | | Now we simply take away eac...

Divide through by x so: (dy/dx) +2(y/x) = 4x Now multiply through by the intergrating factor: e^(| (2/x) dx) = e^(2.ln(x)) = x^2 so you get: (x^2)(dy/dx) + 2xy = 4(x^3) Now integrate the entire equation and ...

Using the factorisation method. the factorised solution will look like (x+a)(x+b) = 0 by multiplying these two brackets we get the equation: x^2 + a.x+b.x + a.b = 0 so vomparing this to the equation in the q...
