Matlab Question. Please show all code and comment through code so I can learn. I will thumbs up your answer. Thanks!

2. The equation describing the water height h in a spherical tank with a drain at the bottom is dh dt where A is the cross-sectional area of the drain hole and Cd is a constant equal to 0.5. Suppose the tank's radius is r 3 m and the circular drain hole has a radius of 2 cm. Assume that the initial water height is h(0) 5 m. Use g 9.81 m/s2. Use the Euler method with a time step of 0.1 seconds to estimate the time it takes for the tank to completely empty. NOTE: You could add code (optional) to automatically break out of the for loop once the height has become negative. HINT: The time it takes to drain the tank is on the order of hours (greater than 5 and less than 10). a. CHEN 1310 Homework #11 Page 3 b. Plot the water height in part (a) as a function of time until the tank is empty [h(t)0]
