Red shift; this phenomena occurs as a result of the distant galaxies moving away from the Earth and all the wavelengths of electro-magnetic radiation being emitted are 'stretched' towards to the longer wa...

One example of a sea defence structure is a sea wall. Sea walls are used to dissipate and reflect wave energy back into the sea, reducing erosion. The wave energy reaches the sea wall, and due to the soli...

first begin by expanding the brackets using the CLAW method (shown using whiteboard diagram)multiply the first of each bracket together, we get x²multiply the first term of the first bracket an...

root3 (root6 + root12) (root3 * root6 ) + (root3 +root12) = root18 + root36= (root9 + root2) + 6= 3root2 +6a= 3 b = 6

v^2 = 12^2+2(-3)(18) = 36. Therefore by square rooting v = 6.To make s the subject first minus u^2 from both sides to have v^2 -u^2 = 2as then divide 2a from both sides to have (v^2-u^2)/2a = s
