Solved in 4 steps
- The density of oil is less than that of water, yet a loaded oil tanker sits lower in the water than an empty one. Why?Determine the height that the water rises in a swinging pool which is 2.0m wide and 4.0m long, with 4.0m depth of water, when a 150 Kg, player goes into it. (The density of water is 1000 kg/m³)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?
- A truck containing a half-filled tank goes up to a ramp which forms 15o from the horizontal. What would be the angle formed by the liquid from its initial state when the truck traveled 100m in 4s from an initial speed of 10 m/s?air is lowered into a tank of water, and records an and his Volume and density. is at the origin, t force acting on 6. What percentage of a floating piece of ice projects above the level of water? Assume a density of 917 kg/m³ for the ice.Through an underground pipe 15 cm in diameter, water circulates at a speed of 4.3 cm / s. Determine: -What diameter should a narrower pipe have, if you want the water to have a velocity of 28 cm / s.-In what time would an 873 liter tank fill up?
- 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 isA large tank is kept full at a height of h = 4 m as shown in Fig. 3. Take the 103 kg/m³. (a) Find the speed v2 of the jet of water water density to be p = = 2 m, then emerging from a small pipe at the bottom of the tank. (b) If y2 find the horizontal distance x (from the base of the tank) that the water stream travels before striking the floor. A1 yı A2 h=y1-y2 Pa v2 y2A person does the back float in a freshwater lake and later does the same in the ocean. In which case is more of the person's body above the water line?
- A large stone is resting on the bottom of the swimming pool. The normal force of the bottom of the pool on the stone is equal to the: O weight of the water displaced. sum of the weight of the stone and the weight of the displaced water. weight of the stone. difference between the weight of the stone and the weight of the displaced water.(c) If the average mass of a person is 75 kg, calculate the maximum number of people that can be on the raft without the top of the raft sinking below the surface of the water. (Assume that the people are evenly distributed on the raft.)The flow rate of blood through a 2.00 x 10-6 m radius capillary is 3.80 × 10- -9 m³/s. X cm/s cm (a) What is the speed of the blood flow (in cm/s)? (This small velocity allows time for diffusion of materials to and from the blood.) (b) Assuming all the blood in the body passes through capillaries, how many of them must there be to carry a total flow of 100.0 cm³/s? (The large number obtained is an overestimate, but it is still reasonable.) capillaries
