A cylindrical tank, shown to the right, has height 10 m and radius 2 m. a. If the tank is full of water, how much work is required to pump the water to the level of the top of the tank and out of the tank? Use 1000 kg/ m for the density of water and 9.8 m/s for the acceleration due to gravity. b. Is it true that it takes half as much work to pump the water out of the tank when it is half full as when it is full? Explain. 2 m ...... О в. dy The amount of work required is approximately (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to the nearest hundredth as needed.) b. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Yes. It takes exactly half as much work to pump the water out of the tank when it is half full. O B. No The amount of work required to pump the water out of the tank when it is half full is approximately rodth as needed)
