Since the SUVAT equations of motion act independently in the horizontal and vertical directions we can use the vertical equations to find the total time (the time when total vertical displacement is zero)...

The temperature of the body is detected by the thermoregulatory centre in the hypothalamus in the brain, which can detect the temperature of the blood. Therefore it recieves information about changes to t...

The d+ carbon on the bromoethane is susceptible to attack by the OH- nucleophile (negative ion with a lone pair)( the lone pair is very important as this carries out the attack!!!).

When the nucleo...

To begin answering this question create a small grid

put 5 on the left hand side and put 2x and -6 seperately at the top of the grid

then you can multiply 5 by 2x to gain 10x and multiply 5 ...

y=5x

The change in Y over the change in X gives the differential of 5x

As the power of 'x' is 1, this is brought down and multiplied by 5 and the power of x is 1-1 = 0. Therefore, the power ...
