This is a unit of electrical resistance

Ohm

Explanation: The units for electrical resistances (also for impedance and reactance) is called Ohm, and Ohm = V/A (volt/ampere) = kg*m^2*s^−3*A^−2

This has sense when you recall that R = V/I, where V is voltaje and I is the current.

An Ohm is represented with the symbol: Ω

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

probably not if net force is zero
