How difficult it is to change an objects motion. Think of a tablecloth; it takes energy to move it from underneath objects on the table, and it takes energy to move the objects themselves on the table.

What is the maximum radiation pressure exerted by sunlight in space ( s = 1350 w/m 2) on a flat black surface? a. 2. 25 × 10−5 p

mel-nik [20]

The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × $10^{-6}$ 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 × $10^{-6}$ P a

For a black surface, P = 4.5× $10^{-6}$ P a

Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × $10^{-6}$ P a

A kernel of popcorn contains a small amount of water and when heated the popcorn pops. How can you explain this to someone

Aliun [14]

When you put a popcorn kernel in a microwave, the microwave heats up the water. The water then evaporates, and the air wants to escape. There will be so much pressure that the skin/shell of the kernel will break, exposing the corn.

How many electrons does nitrogen (N) need to gain to have a stable outer electron shell

earnstyle [38]

It need "3 electrons" to have a stable electronic configuration.

'cause it has 5 electrons in it's outer shell & every atom needs 8 electrons. So, it requires 3 more!

Hope this helps!
