If an object has a mass of 50g and a volume of 10cm^3, what would the density be of the object ( hint, the units for density is g/cm^3)

m=ρV

ρ=m/V

ρ=50/10

ρ=5 cm^3

Explanation:

Density is that how much mass of object takes place in given volume.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

the answer is a. at the equator
