<span>When the two pucks collide, momentum will still be same but it acts in two different directions.
Momentum formula goes like this M = m x v, m is mass and v is speed. That means velocity is inversely proportional to mass.
So the puck with less weight changes the most, so the 0.156 kg puck changes velocity the most

The correct answer is
comets
Comets, in fact, follow a very elliptical orbit around the Sun. In fact, they have the most elliptical orbit of all astronomical objects. According to Kepler's second law, the velocity of an object orbiting the Sun depends on its distance from the Sun: the closer it is to the Sun, the faster it moves, and the further it is, the slower it moves. Due to their very elliptical orbit, the distance of the comets from the Sun change a lot, therefore they experience the most drastic change in velocity (more specifically, they move very fast as they approach the Sun, while they move very slow when they are very far from the Sun).
All of these statements about flux are true, except for the last one - <span>When turning a surface inside of an electric field, the maximum flux is achieved if the electric field vector and the surface vector are perpendicular.
These vectors don't have to be perpendicular, which is why this statement is incorrect, whereas the rest of them are true. </span>
