1. The specific heat capacity of water is 4,180 J/(kg. K) and that of iron is 450 J/(kg. K). You have supplied 10,000 J of energy to 1 kg each of iron and water. How much will the temperature rise
in the water and iron?

No because a circle or pie graph usually shows percentages you'd need a line graph

Ithink it’s 98 because jajajjajansmsmjs

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.
