Questions and Answers

What is the purpose of the experiment described in the text?

  • To measure the viscosity coefficient of a liquid (correct)
  • To determine the weight of steel balls
  • To calculate the acceleration due to gravity
  • To explore the effects of buoyant force

    • What is the role of the steel balls in the experiment?

  • To provide a visual representation of terminal velocity (correct)
  • To observe the effects of buoyant force
  • To measure the density of the liquid
  • To determine the temperature of the liquid

    • Which outcome is NOT intended for students at the end of the experiment?

  • Interpret the origin of viscosity in liquids and gases
  • Set up an experiment to measure liquid viscosity
  • Define the viscosity
