I NEED HELP ASAP NO LINKS!!! I WILL MARK YOU THE BRAINLIEST A person is sitting on a sled and someone is about to push them down a hill.
Which statement is accurate?
1: Forces acting on the sled are paired with unequal and opposite forces.
2: Forces acting on the sled are paired with the force of gravity only.
3: Forces acting on the sled are paired with equal and opposite forces.
4: Forces acting on the sled are paired with the force of friction only.

it should be 3

Explanation:

sorry if it's wrong

graph question answered .. you think better when you are relaxed and happy

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.
