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 14.0 cm deep. **Question:** How far upward from its initial position does the mercury in the right arm rise? **Instructions:** Express your answer with the appropriate units. **Answer Submission:** - **Input Boxes:** - \( h = \) [Value] [Units] **Buttons and Options:** - **Submission Button:** "Submit" - **View Options:** - Previous Answers - Request Answer - **Feedback:** - "Incorrect; Try Again; 5 attempts remaining" **Navigation:** - Return to Assignment - Provide Feedback **Explanation:** This question requires calculating the change in height of mercury in a tube, expressed with units. The answer box is designed for input with separate fields for numerical values and units. It is important to ensure the units correspond correctly to the value provided. Feedback is given if the submission is incorrect, with a limited number of attempts to ensure careful consideration.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
