Two expressions were used for the drag force experienced by a moving object in a liquid. One depended upon the speed, while the other was proportional to the square of the speed. In which types of motion would each of these expressions be more applicable than the other one?

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

hypothesising or postulating

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
