A blacksmith cools a 1.2 kg chunk of iron initially at a temperature of 650°C by tricking 15°C water over it. All the water boils away, and the iron ends
up at a temperature of 120°C. How much water did the blacksmith tricke over the iron? Let = 0.47 x 10 kg. ). water = 4.19 x 10 /kg.
*). and L = 2256 x 100/kg

I’m good with pshycology

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.

What does the start look like

Answer sample (c); // would be best because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest;
