A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation. STEP 1 - Draw ...

The gradient of the line is 3 Find the \(y\)-intercept of the line. The value where the line crosses the \(y\)-axis is 1 Write the equation in the form \(y = mx +c\) where \(m\) is the gradient (3 ...

The equilibrium constant of a chemical reaction is: For the reaction between an acidic compound and water, the equilibrium constant (or acid dissociation constant) is: The concentration of H 2 O is ...

Bernoulli's equation along the streamline that begins far upstream of the tube and comes to rest in the mouth of the Pitot tube shows the Pitot tube measures the stagnation pressure in the flow.
