To find velocity you differentiate displacement with respect to time

Therefore ds/dt = v = (3x2)t²-(12x2)t²+7

Implying v = 6t²-24t+7

630 = 5 x 126 126 = 2 x 63 63 = 7 x 9 9 = 3 x 3 so 630 = 2 x 3² x 5 x 7

What are catalysts? They are substances that speed up the rate of reaction by providing a favourable pathway, of lower activation energy, for the reaction to proceed. A heterogeneous catalyst is one that ...

Both compilers and interpreters are used to translate high level programming languages to machine code. Compilers do this by converting all of the high level code into machine code before running the prog...

The equation of a line is y=mx+c. The first step is to find m, which is the gradient. This is found by dividing the change in the y values, by the change in x values. So in this case, the gradient would b...
