El siguiente circuito en paralelo con una fuente de energia de 200v, dos lamparitas, un aire acondicionado de 3200watts, una llave termica de 20A y una tecla de encendido que representa a una llave. si en un determinado momento se cierra la llave, responda a las siguientes preguntas:a) ¿El aire acondicionado puede funcionar en estas condiciones?b) ¿cuanta corriente electrica entrega la fuente de energia al circuito?

i think the answer is b

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.

ya te mando la respuesta

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
