A moving saw blade and wood are in contact and heat is produced from the kinetic energy and friction between the two objects. Describe all the possible places the RKE can transfer. Whats the answer

The radiated heat from the kinetic energy is transferred speedily across the blade but not in the wood.

Explanation:

The moving saw blade is a metal and metals are very conductive as they have free valent electrons in their outermost shell. So the heat is transferred from the action point to the other end of the saw blade.

Unlike the saw blade, the wood is a poor conductor of heat and would slowly absorb the heat which may not translate the entire wood before the sawing is complete.

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.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
