Acceleration (A)= Angular Velocity² (w²)Displacement (x)Angular Displacement= 2piFrequency (f)Gradient= A/x = w² = [2pi*f]²Rearrange the equation to g...

Note the formula: y - y₁ = m(x - x₁)x, y, x_1, y₁ refer to the values of your given coordinates. 'm' symbolises the gradient of the line you are asked to findRe...

Similarities:Both processes are passive (do not require energy)In both processes molecules move from an area of high concentration to low concentration and therefore down a concentration gradient.Differen...

First put the equation into the correct form by setting it to 0:18x^2-3x-6=0Look for the common factor in the equation and take it out:3(6x^2-x-2)Using the grid method (which I would show on whiteboard) f...
