Terminal Velocity of Rising Bubbles

JEE Main asked Terminal Velocity of Rising Bubbles 4 times in 4 of the 108 shifts Lumi analysed, in 2022, 2023 and 2026. It belongs to Viscosity, in Mechanical Properties of Fluids (Physics). The longest wait between two years asking it was 3 years. In 2022 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2022, 2023 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
