The total solar irradiance (tsi) at earth orbit is 1400 watts/m2 . assuming this value can be represented as a single poynting flux. find the corresponding flux at the solar visible-light surface. explain your methods.
(distance between sun & earth is 150 million km)

3.958 × 10²⁶ watt

Explanation:

Given:

Distance between earth and sun, = 150 ×10⁸ m

Total solar irradiance at earth orbit  = 1400 watt/m²

Now,

Area irradiated () will be =

⇒ =  

⇒ =  

Therefore, the flux = Total solar irradiance at earth orbit ×

the flux =  

⇒the flux = 3.958 × 10²⁶ watt

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

your answer is c! hope this : )
