There are two points 'A' and 'B' on a graph, their coordinates are (0,1) and (10,6) respectively. 1)Find the equation of the line that runs through both of these points.2)Find the equation of a line perpendicular to this through point 'B'.

Draw a graph to see the question more clearly.1) Find the slope using the rise over run formula. ( m = 1/2 ) Put this slope into the equation of a line formula along with one of the points. ( y = (1/2)*x + 1...

The Haber Process converts hydrogen and nitrogen into ammonia in the following exothermic reaction: 3H2+N2=2NH3. Explain the effect of increasing the pressure and why.

According to Le Chatlier's Principle, an increase in pressure favours the side with the least moles, which in this case is the forward reaction. Hence, increasing the pressure would result in an increase in ...

How do you calculate the magnification of an image? For example, if the real size of a cell is 30um and the size of the cell in the textbook is 60mm, what is the magnification?

= size of image/ real size of object Can use the magnification triangle to work this out. Can also use the triangle to calculate each image size or object size, if you already have the scale of magnification...
