Alpha particles which are made up of 2 protons and 2 neutrons (overall positive charge) are fired towards a thin sheet of gold. To ensure any deflection of the alpha particles is only due to the gold shee...

I would use the x-y graph to explain the multiplication of negative numbers

I would also start with 4 x 3, then work my way towards negative numbers, e.g 4x2, 4x1 ......4x-1, 4x-2

Then I wou...

When a conductors carrying current is placed in a magnetic field, the field exerts a force on the conductor and vice versa. Fleming's left hand rule is a tool that you can use to help work out the relativ...

Firstly, all waves transfer energy without transferring matter (particles). 

Waves usually consist of particles vibrating in a particular direction, but not necessarily in the same direction as the...

Speed = Distance/Time Speed = 3 Time = 60 Distance = Speed x Time Distance = 3 x 60 = 120m
