3. A beach ball (the inflated plastic balls that get batted around at beaches or gradua- tions) has a diameter of 39.0 cm and a mass of 150 g. If a fully-submerged beach ball is fastened to the bottom of a pool using a string, what is the tension in the string? find tension in string 4. Horseshoe Falls is one section of Niagara Falls. 2.6 million liters of water flows over Horseshoe Falls every second (2.6 × 106 L/s). The cross-sectional area of the falls can be approximated as a rectangle 900. m wide with a water depth of 0.305 m. What is the average velocity of water going over Horseshoe Falls? 5. Let's pretend it isn't freezing outside and that you are considering opening your car window while driving. If you are driving at 27.0 m/s, what is the difference in pressure between the inside of your car and the outside of your car? Assume that the density of air is 1.30 kg/m³.
