10 Questions
What is the purpose of the experiment described in the text?
To measure the viscosity coefficient of a liquid
What is the role of the steel balls in the experiment?
To provide a visual representation of terminal velocity
Which outcome is NOT intended for students at the end of the experiment?
Calculate the density of the viscous fluid
What happens to the steel ball when it reaches terminal velocity?
It moves with a constant speed
What force opposes the motion of the steel ball in the liquid?
Viscous force
Viscosity is the resistance of a fluid to flow.
True
The unit for viscosity coefficient can be measured in MKS (SI) or CGS units.
True
The viscous force opposing the motion of the steel ball depends directly on the speed of the ball.
True
The terminal velocity is the constant speed at which the ball moves when the viscous force and buoyant force balance the weight of the ball.
True
The steel ball decelerates and eventually comes to a stop before reaching the bottom of the jar.
True
