One arm of a U-shaped tube (open at both ends) contains water (Pwater=1000 kg/m3) and the other contains cooking oil (Poil=900 kg/m3). Part 1: If the height of the cooking oil is 18.0 cm from the point where the two fluids meet, at what height will the water be? See figure below: water oil 18 cm Part 2: What is the pressure in atmospheres (unit of pressure measurement) at the point where the two fluids meet? Part 3: What is the difference in pressure, in atmospheres, between the top of the water and the top of the oil?._. """"'I""""'J"" _ ._._._.. 1. Getting Started: State the important information and summarize the problem. If possible, include a diagram. Note any assumptions you're making. 2. Devise Plan: Devise a plan of attack before diving into the solution. Break down the problem into smaller, manageable segments. Identify which physical relationships you can apply. 3. Execute Plan: Carry out your plan, explaining each step. The argument should be easy to follow. Articulate your thought process at each step (including roadblocks). Any variables should be clearly defined, and your diagrams should be labeled. 4. Evaluate Solution: Check each solution for reasonableness. There are many ways to justify your reasoning: check the symmetry of the solution, evaluate limiting or special cases, relate the solution to situations with known solutions, check units, use dimensional analysis, and/or check the order of magnitude of an answer. Note: If you got stuck in the Execute Plan stage and there is no
