Question 1
A sphere with a radius of 0.02 m is dropped into glycerin at 20°C. The viscosity of glycerin is 1.5 Pa.s. Calculate the terminal velocity.
💡 Hint: Ensure you know the densities involved; look them up or assume common values.
Question 2
A student conducts an experiment measuring the fall speed of different sized spheres in a viscous fluid. Discuss how their results could vary and what parameters influence this.
💡 Hint: Think about how real-life materials can change the weight and resistance.
