You can’t take exams at two different centres in the same ‘series’ (. summer or January). If the timetable permits, you could ask the school to enter you for extra exams, though you might have to pay. Ask your exams officer – they’re the experts and know you son’s situation.
It looks like you’ve read the page on science GCSEs ( http:///science-gcse/ ) so you know the structure. Because of the new flexibility that I describe on that page, the school can organise science in different ways. There are only three exams for triple science. They can be taken together in year 11, or split between yr 10 and 11. Biology in year 10 and the others in yr 11. Or, the school could go down the route of Core science in yr10 and additional plus further addition in year 11.
Centripetal acceleration is the rate of change of velocity. It is caused by the external force that act at a tangent and is needed to make a body move in a circular path at constant speed. For instance if a ball is swung on a string, it requires tension and the ball will go off in a tangent line if the string breaks. Thus, centripetal acceleration can be derived when a body moves in a circular path. Need essay sample on "Physics coursework" ? We will write a custom essay sample specifically for you for only $/page
