3,000ml of an unknown liquid has a mass of 3 kg. What is its density?

The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: {\displaystyle \rho ={\frac {m}{V}}} where ρ is the density, m is the mass, and V is the volume.

what type of charge does it have? negative

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
