Renewable energy has the potential to have all the same applications as non-renewable. But we currently don't have the resources and potential.
So I would say the answer would be B, but this question is somewhat confusing.
Schrodinger developed a famous equation that allows the solutions for electron wave functions to be found given a specific potential. For the case of an atom, Schroginger's equation allows the determination of electron wave functions. These wave functions tell us how electrons are distributed in space around the atom.
Displacement, usually the method that is used to measure the volume of an irregularly shaped object.
1 kg = 1000g
2.43 kg *1000g/1kg = 2430 g
