The magnitude of the force is given by F = BILsin(θ) . I is the current flowing through the wire, L is the length of the wire in the magnetic field and B is the magnetic field strength. The angle θ, is th...
Heat can travel through 3 different processes: conduction, convection and radiation. Conduction is caused by atoms bumping into each other, transferring energy and therefore heat. An example of this would...
The lines are radial and as distance increases from the sphere the further away the lines get from each other in both. The differences are that gravitational lines are directed towards the sphere an...
Energy cannot be destroyed or created - it is always transferred between different objects in different forms. Hence, energy is 'conserved'. The most basic example is dropping a stationary rubber ball fro...
Current is defined as the amount of electrons that flow through a wire per secondVoltage is defined as the amount of energy that each electron carries as it passes throug...
