Using the same array from q3 above, trace the complete execution of the merge sort algorithm. show the subarrays that are created by the algorithm and show the merging of subarrays in the larger sorted array. int[] n1 = {63, 9, 45, 72, 27, 18, 54, 36}

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
