Immediately above the sun's photosphere is the which is the sun's lower atmosphere immediately above the sun's photosphere is the which is the sun's lower atmosphere. a. chromosphere b. solar wind c. corona d. core

The chromosphere is a thin layer of the atmosphere of the sun (or any other star) above the photosphere and below the corona. It consists mainly of hydrogen and helium.

This layer is very faint and reddish when it becomes visible, for a few seconds, at the beginning and end of a Solar  eclipse and its appearance is not homogeneous.

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.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
