Answer:

(c) At much higher speeds, where N′R is greater than 106, flow becomes turbulent everywhere on the surface and behind the sphere. ... Instead, viscous drag increases, slowing acceleration, until a critical speed, called the terminal speed, is reached and the acceleration of the object becomes zero

Answer:

If the magnitude and the direction of the velocity of the fluid at any point of it change irregularly and continuously and never remain constant then that kind of flow is known and turbulent flow
