At liftoff, an orbiter and External Tank carry 3.1644 x 106 L of fuel. The density of the fuel was 1.14 g/cm3, what is the mass of the fuel in Mg

Hahahah jsu’s hsjshshsh. shjshshshsh.

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 independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
