2076 Set C Q. No. 9d The velocity of a particle executing
simple harmonic motion is 16 cms-1 at a distance of 8 cm
from the mean position and 8 cms-1 at a distance of 12 cm
from the mean position. Calculate the amplitude of the
motion,

answer: strength i guess

explanation:

uranium fissions/breaks up giving out energy and neutrons

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
