The intensity of electromagnetic waves from the sun is 1.4 kW/m” just above the earths atmosphere. Eighty percent of this re

science physics

Answer 1

Answer #1

Solution)

Given,

Intensity, I=1.4 kW/m^2

Area, A=33 *55 cm

We know,

Energy= Intensity*time*Area

So, Energy=(0.8*1.4*10^3)*(0.33*0.55)*(0.5*3600)

Energy= 365904 J (Ans)

Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of 1.38 kW/m2. (a) Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Sun's rays and that all the incident energy is absorbed, calculate the force on Earth due to radiation pressure. (b) For comparison, calculate the force due to the Sun's gravitational attraction. Assume that the speed of light and Earth radius are 2.998 × 108 m/s and 6.37 thousand km...

Electromagnetic Waves UV Radiation Some of us are all too familiar with the ill- effects of over-exposure to ultraviolet (UV) electromagnetic radiation, namely, sunburns (solar erythema). UV radiation can kill the skin cells immediately below the surface (part of the epidermal layer). Over the course of several minutes or several hours, as enough skin cells are killed or damaged, the body's natural immune response is triggered. The body responds to the damage with increased blood flow to the capillary bed of...
