Raindrops fall from a standstill and meet the wind blowing in the horizontal direction. The following statement is correct: () A. The greater the wind speed, the longer the raindrops fall.

A, the movement of raindrops is divided into horizontal and vertical directions. According to the independence of each movement, the divided movement and the combined movement have isochronous knowledge, and the falling time of raindrops remains unchanged, regardless of wind speed. So, A is wrong and C is right.

B, the wind speed increases, the horizontal component speed increases, and the vertical component speed remains unchanged. According to the parallelogram law, the approaching speed increases when landing. So, B is wrong.

D, when the wind blows horizontally, the direction of the combined speed and the direction of the combined force are not in a straight line, and they will do curvilinear motion. So, d is wrong.

So choose C.
