Electromotive Force (EMF) is the measure of how much energy a source like a battery gives to the charges in a circuit. As with most things, this energy source is not 100% efficient, and has an associated ...

A transformer is designed to step-up or step-down a voltage in a wire to make transferring electricity more efficient. To do this they contain two isolated coiled wires (of varied lengths depending on the...

Newtons law of gravitation can be described as: The force experienced by a body proportional to the product of the two masses the interaction is between, the gravitational constant 6.67x10^-11 ,...

This question is concerned with balancing forces. First, we must consider what forces are acting on the satellites. What is stopping the satellite from shooting off into space and what is preventing it fr...

We know that the object is moving at 5m/s already telling us that the distance the object has travelled increases with time. Plotting distance on the y axis against time on the x axis we therefore expect ...
