Pot a and b both have plain soil, bean seed and the same amount of light. pot b receives more water after 50 days the plants are measured based on the date. what is the correct conclusion?

Plants in pot B will outgrow plants in pot A, or die from excess water.

Explanation:

The two pots provide the same factors for the bean seeds to germinate and the plants to grow strong and healthy, however, pot B receives more water than pot A and this can make plants from can B grow more than plants from pot A, or not. This uncertainty is generated by the fact that we do not know what quantities of water are being placed. Pot B may be receiving the ideal amount of water for the bean plants, or receiving excess water which will cause these plants to die.

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

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.
