(2)(3)(2)=12⇒ D=M/V ⇒ D=94/12=7.8333(repeated) g/m³
Answer:
Explanation:
for earth -sun system
E = σ T⁴ , E is radiation emitted by sun at temperature T
E = 4π R₁² x solar constant on earth , R₁ is distance between earth and sun.
for marsh -sun system
E = σ T⁴ , E is radiation emitted by sun at temperature T
E = 4π R₂² x solar constant on Mars , R₂ is distance between earth and sun.
from two equation ,
4π R₂² x solar constant on Mars = 4π R₁² x solar constant on earth
solar constant on Mars = (R₁ / R₂ )² x solar constant on earth
