This is beacuse it is caused by light scattering of light in the atmosphere. When the moon rises blue light is caused and scattered also caused by earth's atmosphere and it is black on the moon as there is no lunar atmosphere , so no light scattering.
Answer:
1) Mass of the grain is
.
2) 0.08901 kg of sand would have surface area equal the surface area of the cube.
Explanation:
1) Radius of the grain,r = 64.8 µm =
Volume of the sphere =
Volume of the grain of a sand:


Density of a grain of sand = 
Mass of a grain of a sand = M


Mass of the grain is
.
2) Surface are of sphere: 
Surface area of a grain:


Length of the cube = a = 0.514 m
Total surface area of cube ,A'= 

let the number grains with area equal to total surface area of cube be x.


Volume of x number of grains :V'



Mass of
of sandL:
=
0.08901 kg of sand would have surface area equal the surface area of the cube.
