The sodium D-line is formed by the transition of electrons from one energy state to another energy state, whereby the energy of atoms decreases by 3.37 · 10–19J. Determine the wavelength of the sodium D-line.

lower, it's not as dense as chocolate syrup.

choco syrup is more like a solid than a liquid and even turns solid if it gets slightly cold,

orange juice however is a 95% liquid and has a very low viscosity

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
