PLEASE HELP, I WANT TO ANSWER QUESTION 5Part 1: Show That a Moving Magnet Can Create an Electric Current 1. Make or obtain a coil of lightly insulated copper wire. The coil should have a hole in the center that is
large enough to allow a bar magnet to easily pass through the coil.
2. Make the ends of the wires on the coil bare either by using wire-stripping pliers to strip off the
insulation or by using sandpaper to scrape off coating-type insulation.
3. Use alligator-clip wires to connect the coil to an ammeter or multimeter.
4. Hold a bar magnet by its north end and slowly pass it through the center of the coil and out the other
side. Repeat several times, observing the reading on the meter.
5. Describe what you would expect to see. What do you conclude?

the results is a decrease in air temperature with an increase of altitude.

explanation:

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.
