its fire
Answer:
b
Explanation:
electrons lie in the orbits of the atom. they are negatively charged and they are very small in size. they have very less mass than proton. ele tron has 1/1840 mass of proton.
Mass of cube = 130g
Volume of cube = 2.97g
Density = m/v
D = 130/2.97
D - 43.77 g/cm³
(b) In SI system = 43.77x 1000
= 43770 kg/m³
What is density?
Density is the ratio between the mass of the substances and the volume of the substance.
