I = average intensity of sunlight reaching at Madison = 2000 Js⁻¹m⁻²
A = area on which the light strike = 4.80 cm² = 4.80 x 10⁻⁴ m²
energy received per second by the area is given as
E = IA
inserting the values
E = (2000) (4.80 x 10⁻⁴)
E = 0.96 J
λ = wavelength of the photons in the sunlight = 510 x 10⁻⁹ m
c = speed of light = 3 x 10⁸ m/s
h = plank's constant = 6.63 x 10⁻³⁴ J-s
n = number of photons received per second
energy received per second is also given as
E = n h c /λ
inserting the values
0.96 = n (6.63 x 10⁻³⁴) (3 x 10⁸) /(510 x 10⁻⁹)
n = 2.5 x 10¹⁸ per second
Answer: it C
Explanation: Because is the only that makes sense and the only one that seems right
Answer: Heat is removed from a gas, and the substance becomes a liquid.
