To start, let's get a feel for how large the acceleration due to the sun's gravity is near the earth's orbit, where the spacecraft will depart. Find what this acceleration would be at a point that is 1.4E 11 m from the sun. The mass of the sun is 1.99E 30 kg. Enter your answer as a fraction of g (the acceleration due to gravity near the surface of the earth). This part of the problem has nothing to do with the sun's radiation - we're just trying to get a sense of scale.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

snell's law

refractve index = sin incidence / sin refraction
