In order to differentiate a number, 2 steps are needed to be made. The first is to reduce the power of the number by 1 and then multiply that value to the first number. I will run you through the given qu...

If we first factorise the top and the bottom of the equation we can see that the top is equal to (x+6)(x+3) and the bottom is (x-3)(x+3). This means we can divide the top and bottom by (x+3) giving us a r...

(draw diagram on whiteboard) As the potential difference increases, the current increases, since V=IR (where V is the potential difference, I is the current and R is the resistance). Initially the current...

When light is shone onto a piece of metal, if the light is below a certain frequency, no photoelectrons are emitted. Only if the light is above a certain frequency, known as the threshold frequency, are p...
