A student is investigating how the pressure exerted by a gas varied with the volume of the gas. The initial pressure was 1.6x10^5 Pa, with the volume being 9.0cm^3. Calculate the volume of the gas when the pressure was 1.8x10^5 Pa

pxV=constant
(1.6x10^5) x (9.0) = (1.44 x 10^6)
p= (1.44 x 10^6)/(1.8 x 10^5) = 8 cm^3

Point A has coordinates (-1,3). Point B has coordinates (2,-3). Find the equation of the line L that goes through these two points. Point C has coordinates (0,1). Hence or otherwise, find the equation of the line perpendicular to L that goes through C.

First we use the equation gradient = (y1-y2)/(x1-x2) to find the gradient of the line L, using point A (-1,3) and point B (2,-3). This gives us gradient = (3-(-3)/(-1-2) = (3+3)/(-3) = -2. Now we subst...
