Grace is trying to decide what to wear. She looks at her thermometer and it reads 307 K. What is the temperature in celsius?

A) 1.1 °C
B) 34 °C
C) 580 °C
D) 84,000 °C

The answer is B. 34 degrees. If you convert 307 Kelvins (K) you get 33.9 degrees Celsius (C) which rounds to 34 degrees.

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.
