Simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of a body and its direction of motion.

The average intensity of the sunlight in Miami, Florida, is 1040 W/m2. What is the average value of the radiation pressure due t

iogann1982 [59]

Answer:

The average value of the radiation pressure due to this sunlight in Miami is 3.467 x 10⁻⁶ N/m²

Explanation:

Given;

the average intensity of the sunlight in Miami, I = 1040 W/m²

the average value of the radiation pressure = ?

Radiation pressure is calculated as;

$Radiation \ pressure = \frac{I *C_R}{C}$

Where;

I is the average intensity of the sunlight

CR is solar radiation coefficient = 1

C is the speed of light = 3 x 10⁸ m/s

$Radiation \ pressure = \frac{I *C_R}{C} \\\\Radiation \ pressure = \frac{1040 *1}{3*10^8} \\\\Radiation \ pressure = 3.467*10^{-6} \ N/m^2$

Therefore, the average value of the radiation pressure due to this sunlight in Miami is 3.467 x 10⁻⁶ N/m²
