Your friend is trying to move a couch. No matter how hard they push, the couch will no budge. Explain to your friend why the couch is not moving even though he is applying force.

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.

Well i am not very good at this but  i would be guessing 1hope i  

The answer is continental shelfs

Kindly show the food chain.to double population of rabbits, decrease the number of animal which depends on rabbit as food ,i.e., animal lying above rabbit in food chain.
