I have severe case of "smiling" depression and a serious case of ADHD. My parents don't know about this and I don't want to tell them bc they are part of the reason of it. They don't do anything bad to me but they fight a lot and get angry at me. I also have thoughts about k*ll*ng myself and hurting myself. What should I do?

the higher the current the higher the mag field around it the higher the influence on the compass

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.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
