Scientists believe they know everything there is to know about the atom true or false and explain..

False

Explanation:

Scientist still haven't developed a atom. They have come up with a name but they haven't seen the atom before. Also they do not know how we have we have come to this world. There are many theories, ie, the big bang theory

I think No.

Explanation: Because you can't not know everything about something but therefore they do know a whole lot about these little things in our body such as the atom. The atom is everything we have in our body or everything is really because of atoms. Our scientist still have questions about the atoms, even if there isn't much to ask anymore. But you can not know about everything about the atom, its impossible, but it can be done with a couple more years we pretty much have basically all we have to know about atoms.

There are three ways that scientists have proved that these sub-atomic particles exist. They are direct observation, indirect observation or inferred presence and predictions from theory or conjecture. Scientists in the 1800's were able to infer a lot about the sub-atomic world from chemistry.

But it can be possible that they do know ALMOST everything but im sure they don't know every detail about Atoms.

Hope this helps!

i think it's 35 meters

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
