Aballoon is released from the top of a building. the graph shows the height of the balloon over time. what does the slope and y-intercept reveal about the situation? a. the balloon starts at a height of 0 ft and rises at a rate of 100 ft. b. the balloon start at a height of 10 ft and rises at a rate od 0 ft. c. the ballon startes at a height of 0ft and rises tat a rate of 10 ft.

It would be easier to answer if there was a graph, but I think its A I could be wrong :/

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.
