The volume of a cylinder = (pi).r².hAs the diameter is given in the question, we need to halve it to get the radius --> r = (4x+2)/2 = 2x+1This means the volume of the cylinder = (pi).(2x...

To determine the characteristics of a graph, we need to examine what we are been shown in the question. Below is an exam style question:By looking at both the graph and the equation, we can see that in th...

Through energy conservation, we can determine that no energy is lost and thereforeKinetic energy = Electrical energyAs a result the following equation is present where both sides represent energy:(m*(v^2)...

y = e^x is an interesting function because for any value of x, the corresponding value of y is always equal to the gradient of the curve at that point.Therefore, f(x) is equivalent to f'(x) - th...

The cell surface membrane is formed of a phospholipid bilayer, in which the hydrophillic phosphate heads point outwards and the hydrophobic tails point inwards. This forms a barrier for large molecules su...
