Which two things determine an object’s momentum? a. speed and distance traveled b. mass and velocity c. speed and velocity d. direction and speed

Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.

the answer is B mass and velocity

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 !

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
