How to use fleming's left hand rule.

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 relative d...

How is a particle moving in circular motion accelerating but not varying speed?

When a particle moves in circular motion, the resultant centripetal force acts radially towards the centre of the circle. Since there is a force there must be an acceleration on the particle due to Newtons 2...

A box is pulled with a rope at 26° to the horizontal and a tension of 120N. What is the work done in pulling it 5 metres?

Work done = Force in direction of motion (horizontal in this case) x distance. Force in direction of motion is 120 x cos(26) (draw a diagram to help visualise this) and distance is 5. Therefore work done is ...

What's the difference between longitudinal and transverse waves?

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 way the en...

What are the different classifications of sub-atomic particles?

Firstly, particles can be split up into to main categories: hadrons and leptons. Hadrons interact with the strong force and are made of quarks. Leptons don't interact with the strong force and are fundamenta...
