Osmosis is a process whereby molecules of a higher concentration go to an area of a lower concentration. For instance, if you have a bag made of porous material, such as cellulose, you fill it with orange...

the four suvat equations are:s=ut+0.5at²v²=u²+2asv=u+ats=0.5(u+v)ts=displacement u=initial velocity v=final velocity a=acceleration t=time for most suvat equations you wil...

This method is known as completing the square. To find the constant a, we must halve the coefficient of x, which in this case is 4. This is to compensate for the double term when expanding the brackets. S...

a) y = x² + 3x + 1b) y = 2x + 3At points of intersection (a) = (b).2x + 3 = x ² + 3x + 1Note this is a quadratic expression which will solve for 2 unique solutions, providing the dis...
