We are considering an earth-venus transfer trajectory where the angle between theinjection point (at earth with an injection velocity parallel to earth’s velocity) and the arrivalpoint (at venus) is 150 degrees. what is the heliocentric velocity (magnitude and direction)of the spacecraft when it intercepts venus’ orbit? what is thev[infinity]of the spacecraft withrespect to venus (in vector form)? assume a circular orbit for both earth and venus aroundthe sun.

d.7.5cm is your answer

true tan speed = ang vel x radius

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.
