Using the solar constant, estimate the rate at which the whole earth receives energy from the sun. (hint: think about the area of the earth as seen from the sun)

1.475×10²⁴ W

Explanation:

I = Solar constant of the sun = 1362 W/m² (measured using satellites with value 1.3608 ± 0.0005 kW/m² the error is due to fact that solar output is not always constant)

r = Radius of earth = 6371 km = 6371000 m (mean radius)

A = Area of earth = (4/3)×π×r³

=(4/3)×π×6371000³ = 1.083×10²¹ m²

P = I×A

⇒P = 1362×1.083×10²¹

⇒P = 1.475×10²⁴ W

∴ Rate at which the whole Earth receives energy from the Sun is 1.475×10²⁴ W

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
