(b) Using your graph of Vx against t to help you, sketch (not on graph paper) a graph of the distance travelled by the train against time for the whole journey You do not need to calculate any actual distances for this sketch but you should concentrate on getting the general shape correct and each axis should have an indication of the 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 !
