Original energy: GPE=509.81m KE=0 Final energy: GPE=0 KE=(1/2)mv² Therefore (1/2)mv² = 50m9.81 . The m cancels and simplifying the equation we are left with v^2...

The external intercostal muscles contract which moves the diapraghm upwards. This reduces the volume of the thorax and therefore with less space, the pressure in the lungs goes up. The pressure in the lun...

For this question we would start by making f(x)=y. As we know the laws of logs, we can say that ln(x²)=2ln(x), therefore our equation can now be written as y= 2ln(x) - 4 . From this point, we w...

Analyse the integral, common functions in which integration by parts is the best method include lnx and polynomials of x multiplied by exponential functions or sine and cosine functions. If this is the ca...

Whilst they can initially seem confusing, questions beginning with ‘To what extent’ simply require you to express your own viewpoint, backed up with substantial evidence from the text. This type of questi...
