The equation of a straight line is usually given in the form y = mx + c. To prove that two lines are parallel we will need to show that both lines have the same gradient. The gradient of a line is the slo...

first, convert to metres:10cm = 0.1mlens power = 1/focal lengthpower = 1/0.1 =10units are Dioptres, Dso the power of the lens is 10 D

Increase the surface area of the magnesium, for example by using a powder.Increase the temperature of the reaction.Add a catalyst
