a scientist uses a water †an k lacated at a height of 27m from the ground to generate electric power to run a 50W bulb. He installs a water driven wheel generator on the ground if the capacity of †an k is 500L and efficiency of generator is 80% then the time taken for which he can keep the bulb on with a full †an |
