Statement A: An object falling through a viscous medium eventually attains terminal velocity
Statement B: All the rain drops hit the surface of the earth with the same constant velocity
Statement B: All the rain drops hit the surface of the earth with the same constant velocity
View answer and explanation
Correct option: B
Statement A is true and statement B is false
The correct answer is B (Statement A is true and statement B is false) because objects in viscous fluids reach terminal velocity, but raindrops don't all have the same constant velocity.
