The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × 
P a. So, the correct option is (b).
Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data
Solar constant ( S ) = 1350W / m ^2
Now, the radiaton pressure is given by
P = 2 S /c
where c is the speed of the light
P = 2 × 1350 /3 × 10 ^8
P = 9 × P a
For a black surface, P = 4.5× P a
Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × P a

Answer:
Geothermal power comes from Earth's internal heat
Explanation:
The description applied to power sources tends to match the names applied to the source of energy. Sometimes Latin, or other word derivations are used.
For example, "hydro-" refers to water, so it is no surprise that hydroelectric power comes from the movement of water. Of course, "nuclear" refers to the nuclei of the atoms that are split to release energy in a nuclear power plant. Similarly, "geo-" refers to Earth, and "thermal" refers to heat, so "geothermal" energy is the name given to energy derived from Earth's heat.
Answer:
What elements?
Explanation:
The alkali metals are softer than most other metals. Cesium and francium are the most reactive elements in this group. Alkali metals can explode if they are exposed to water.
Not sure if this what you were talking about but here
This from google btw not gonna lie
they are made by of two types of elementary particles
electrons and quarks
