In 2D kinematics, which of the following variables is not a vector and therefore cannot be split into x and y components? 1) Displacement 2) Time 3) Acceleration 4) Velocity​

gravity

explanation:

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

snell's law

refractve index = sin incidence / sin refraction

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
