Define the tesla
One tesla is the magnetic flux density that produces a force of 1N on a wire of length 1m carrying a current of 1 amp perpendicular to the field
Where do the most dangerous waste products of nuclear fission come from?
The most dangerous waste products are those fission fragments from the fission of uranium-235 or fuel rods
What do we have to say when explaining how nuclear waste is stored underground?
We have to say that the waste is stored deep underground, not just underground
What can be said about a point in a gravitational field if the field lines converge at that point?
The density at that point must be higher than the surrounding material
What equation do we use to find the speed of a particle when accelerated through a potential difference?
