In a coal-fired thermal power station, the thermal energy released during the complete combustion of 1kg of carbon is worth 20MJ. In a thermal power station to release by the complete combustion of 1m to the cube is worth 35.8 MJ (1MJ = 10 power 6 J). Question:
Using a proportionality table, calculate the energy released by the combustion of 5 tons of coal then by the combustion of 25m cubed of methane?

Please Help me, Is for tomorow

It may possibly be c i think |-/

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

The correct answer should be b let me know if i’m wrong
