A charged particle in a cyclotron moves in a circle with radius 5mm. If the field in the cyclotron is 0.06 T and the velocity of the particle is 2.4x10^7, what is the charge-mass ratio of the particle?

Firstly, we should equate the centripetal force to the force on a moving charge using equations from our formula booklet: (force on a moving charge): F = Bqv(centripetal ...

Draw a distance-time, speed-time, and acceleration-time graph for an object moving at a constant velocity of 5m/s for 10 seconds.

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 ...

A typical question is about energy transfer - Explain the process of convection and give an example of where we can find them

Molecules in the air encounter an energy source, they gain energy and begin to heat up which causes them to vibrate faster and become less dense which causes them to rise. As they rise, they begin to lose...

How does Ice make drinks Ice cold?

Ice, in it's solid form, is at a maximum temperature of zero degrees Celsius. You might expect that a small volume of Ice might cool say a 25 degree drink to somewhere halfway between 0 and 25. This is no...
