At noon on a clear day, sunlight reaches the earth\'s surface at madison, wisconsin, with an average intensity of approximately 2.00 kj·s–1·m–2. if the sunlight consists of photons with an average wavelength of 510.0 nm, how many photons strike a 4.80 cm2 area per second?

Intensity of sunlight at given position is defined as power received per unit area

so here we can say

area  on which photons are received is given as

now we can find the power received due to sunlight

now we can say this power is due to photons that strikes on surface of earth

so here we can say

given here that

so it will strike 2.47 * 10^18 photons on given area per second

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

where's the following? you gotta add it to know what the choices are
