As an acid is being added to a base, you first need to calculate what is left after they react. Without doing any calculations, we can already see that the acid is in excess as both solutions have the sam...

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...
