You make the following measurements of an object 42kg and 22m what would the objects density be. show your work

density = 1.90909 kg/m³

Explanation:
The measurements given are:
42 kg which gives us the mass of the object
22 m³ (not 22 m) which gives us the volume of the object

Density can be calculated as follows:
density = mass / volume
density = 42 / 22
density = 1.90909 kg/m³

Hope this helps :)

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.

An em wave does not require a medium, while a mechanical wave does.
