Planet X has a mass of M and a radius of R Planet Y has a mass of 3 M and a radius of 3R. Identical satellites orbit both planets at a distance Rabove their surfaces, as shown above. The planets are separated by such a large distance that the gravitational forces between them are negligible.
How does the gravitational field gx at the surface of Planet X compare with the gravitational field gy at the surface of Planet Y?

Definitely the indoraptor

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.

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
