Density and PressureSign up

be able to use the equation density rho = m/V · understand how to use the relationship upthrust = weight of fluid displaced · (a) be able to use the equation for viscous drag (Stokes' Law), F = 6 pi eta r v. (b) understand that this equation applies only to small spherical objects moving at low speeds with laminar flow (or in the absence of turbulent flow) and that viscosity is temperature dependent · CORE PRACTICAL 2: Use a falling-ball method to determine the viscosity of a liquid
