To answer this question, we will need the following equation: SPEED = DISTANCE/TIME (A multiplication and division triangle will be shown)i) The speed of the car is calculated by doing 100 metres/ 20 seco...
A cluster of dust collapse under gravity. A protostar is then formed. The protostar starts fusing in Hydrogen to become a main sequence star. The star then fuses Hydrogen to create larger elements. Depend...
Water has a very high specific heat capacity, it is fair to assume bed-sheets and bedding items have a much lower specific heat capacity. If an object has a high temperature and is in surroundings at a lo...
The first thing to note is that the book is sat on the table, so it is stationary. From newtons laws, we know it must have 0 total force acting on it. Every object on the earth feels a force downwards due...
Define p=momentum, E=electric field.Firstly we know that:1) ∆p/∆t = F - definition of momentum2) F = Eq - force on particle in an electric field caused by a voltage3) E = V/d - definition of electric fiel...
