Hey. Here are the questions I'm a bit stuck on: 1) The joule is not a base unit. There are several equations which could be used to define the physical quantity energy. Find at least two of them 2) Use one of the eqautions you have foundnto find the combination of base units equivalent to the joule. I have searched the internet but cannot find any relevant answers? I think it is along these lines, but im not sure: The joule is equal to: Newtons * metres Coulombs * volts Watts * seconds The joule is also equivalent to: metres^2 * kilograms * seconds^-2 Any help and clarification would be much appreciated - thank you.
