A student carries out an investigation into the rate at which oil flows through a funnel. The diagrams illustrate the setup and show the volume of oil in the measuring cylinder at the beginning of the experiment, and again after one minute. What is the rate of flow of oil through the funnel over the one minute?
- A$0.73\,\text{cm}^3\,\text{s}^{-1}$
- B$0.80\,\text{cm}^3\,\text{s}^{-1}$
- C$44\,\text{cm}^3\,\text{s}^{-1}$
- D$48\,\text{cm}^3\,\text{s}^{-1}$
