Explain how measuring the time and distance it takes for a marble to drop through a graduated cylinder tells you about the liquid’s viscosity. The slower.

Explain how measuring the time and distance it takes for a marble to drop through a graduated cylinder tells you about the liquid’s viscosity.The slower the velocity, the more

viscous the liquid. The faster the velocity, the less viscous.
