What is the definition of a volt
If 1 joule of Work is done in moving 1 coulomb of charge between two points then the potential difference between those points is 1 volt.
How do you move a charge in an electric
In order to move the charge against the electric field, Work must be done. As the charge is released, it is accelerated towards the positive plate due to the field between the plates
How can the magnitude of the velocity of charge can be calculated as follows
Ew=Ek Q.V.=1/2mv^2 2QV=Mv^2 V^2=2QV/m V=square root of 2GV/m
How does the right hand rule Work
Force=thumbs
Pointer finger= magnetic field
Middle finger= electron flow
How is alpha decay represented
4 4
He or a
2 2
How is beta decay represented
228 228 0
Ra -> Ac+ e
88 88 -1
How can alpha decay be recognised
Alpha decay can be recognised by the MASS NUMBER decreasing by 4 and the ATOMIC NUMBER by 2
How can beta decay be recognised
Beta decay can be recognised by its MASS NUMBER staying the same and its ATOMIC NUMBER by 1
Describe nuclear fission
Nuclear fission is the break up of a large nucleus into a smaller nuclei,usually with the release of neutrons as well
Describe nuclear fusion
Fusion is the joining of smaller nuclei to create a large nucleus
Describe mass energy equivalence
Whilst the mass number is conserved is nuclear reactions, when the total masses before the reaction and after the reaction are compared to the energy released through e=mc^2
