Some of these sources are man made although the main source is from the environment. Radon gas from rocks and cosmic rays from the sun are the main enviromental sources. For man made sources, the main sou...

(Using diagrams to aid explention)This is a common difficulty students with Newton's third law, because in isolation it makes sense; If i am pushing a cart, and the cart imparts an equal amount of force o...

This question is relating to the balancing of forces on a moving object.
The force on the skydiver will be equal to its weight multiplied by its acceleration (the acceleration will be equal to 9.8m/s...

It is important to understand that Q=It and therefore by rearranging the equation we know that 1 amp means one coulomb of charge passing through a point every second in the circuit. Therefore we multiply ...

A coulomb the amount of charge that passes in 1 second when the current is 1 ampere.Q = It t = 5 x 60 = 300 (s) we must use Si units in physics hence the conversion to seconds here. Q = 5 x 300 Q = 1500 (...
