Write a function called echo that takes as argument a list and returns a copy of that listwith each element duplicated right after it. here are some examples of how your program should behave on python idle. > > > echo(['a','b','c'])['a', 'a', 'b', 'b', 'c', 'c']> > > echo(['x','y'])['x', 'x', 'y', 'y']> > > echo([85, 72, 61])[85, 85, 72, 72, 61, 61]> > > echo([85, "abc", 6.79])[85, 85, 'abc', 'abc', 6.79, 6.79]

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.
