To factorise the equation, we first need to find one of its roots. To do this, we need to find values of x for which f(x)=0.First we will guess x=1.So f(1)=2(1³) - 7(1²) + 2(1) + 3 =...

Once you have a structure to follow, writing a paragraph is a lot easier. The following structure works for any paragraph, no matter how long it is. It's called PEEL. P - Point. Try and summarise the poin...

Firstly, keep calm! This is your opportunity to have fun exploring your own ideas on paper. When you get the question, try to break it down. For example, if it's a "how far do you agree that..."...

The net diffusion of water from an area of high concentration to low concentration across a partially-permeable membrane. 3 key elements to the definition1) Diffusion of water2) high conc to low conc3) pa...

Firstly, we want to define what information we know from the question: ∆Q = 18000C; ∆t = 300s, P = 13.8kW
Therefore, to calculate the resistance we can use the power equation, P=I²R, and c...
