Answer to Question 1

Props to you, cheers.

Answer to Question 2

Answer: The water in one side of the filled U-tube pushes water up the other side until the pressure at the bottom of both sides of the tube is equal. It then follows that since water pressure is dependent on depth, the equal pressures at the bottom correspond to equal depths of water in each side.
