- Anyarometer is a device used to measure the density or a liquid, it is a cylindrical tube weigntea at one ena, so that it floats with the heavier end downward. The tube is contained inside a large "medicine dropper," into which the liquid is drawn using the squeeze bulb (see the drawing). For use with your car, marks are put on the tube so that the level at which it floats indicates whether the liquid is battery acid (more dense) or antifreeze (less dense). The hydrometer has a weight of W-5.81 x 102N and a cross-sectional area of A -8.70 x 10³ m². How far from the bottom of the tube should the mark be put that denotes (a) battery acid (p=1280 kg/m³) and (b) antifreeze (o= 1073 kg/m³)? Hydrometer (a) h= Marks for two types of liquidsSubject: physicsFind the fluid force on the vertical side of the tank, where the dimensions are given in feet. Assume that the tank is full of water
- Water c omes out of the bottom of this water tank at a speed of 4.22 m/s. If the water is directed upward, how high will the water go?if water flows through a pipe with a 1 meter diameter at a consistent linear velocity of 5 m/s and then enters a narrower pipe (diameter = 0.05 meters), determine the velocity of the water after entering the smaller pipe.A professor drops a water bottle whose lid is closed from certain a certain height. The water bottle has a hole in it and water is leaking. What happens when the bottle is dropped? Explain in a short paragraph (five sentences) why the water stops leaking. Use diagrams and figures as necessary.
- Suppose that you release a small ball from rest at a depth of 0.600 m below the surface in a pool of water. If the density of the ball is 0.300 that of water and if the drag force on the ball from the water is negligible, how high above the water surface will the ball shoot as it emerges from the water? (Neglect any transfer of energy to the splashing and waves produced by the emerging ball.)Water flows through a water hose at a rate of Q1 = 640 cm3/s, the diameter of the hose is d1 = 2.2 cm. A nozzle is attached to the water hose. The water leaves the nozzle at a velocity of v2 = 11.6 m/s. Calculate the speed of the water in the hose, v1 in meters per second.Water leaks from a hole in a water tank which is a 17.66 meters below the surface of the water which is 3.83 meters deep.The velocity of the water just leaving the hole is
