Question: A U-shaped tube, open to the air on both ends, contains mercury. Water is poured into the left arm until the water column is 17.7cm deep. How far upward from its initial position does the mercury in the right arm rise (in mm)? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
