A newly discovered planet has a mass equal to one eighth of the Earth's mass and a radius
equal to one half of the Earth's radius. If the
gravitational field strength at the Earth's surface
is g, what is the value of g on the new planet's
surface?

It is d, all the other ones say incorrect answer .

The answer is 12, for the points

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.

Ithink the answer is d
