- A fluid with density 1200 kg/m flows through this pipe. As the first location, A, the fluid travels at 7.5 m/s and at the second location, B, the fluid travels at 11 m/s. What is the difference in pressure between the two points? O-1.9 x 10 Pa +3.8 x 103 Pa -2.5 x 104 Pa -3.9 x 10 Pa O +5.0 x 104 Pa1. Two blocks of different sizes and masses float in a tray of water. Each block is half submerged, as shown in the figure. Water has a density of 1000 kg/m³. What can be concluded about the densities of the two blocks? 2x 2x (A) The two blocks have different densities, both of which are less than 1000 kg/m³. (B) The two blocks have the same density of 500 kg/m. (C) The two blocks have the same density, but the density cannot be determined with the information given. (D) The larger block has a greater density than the smaller block, but the densities of the blocks cannot be determined with the information given.Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 46.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the bone: m3 What is its average density? average density of the bone: kg/m³ about us privacy policy terms of use contact us help careers
- Please help thank you!help A piece of wood floats in water. It measures 49 cm x 12 cm x 11 cm, and has a density of 500 kg/m3. Find the percent of the wood that's underwater, if the density of water is 1000 kg/m3 Hint: Answer should be between 0 and 100 % Buoyancy problem: draw the wood and the forces on it - namely gravity pulling down and the buoyant force of the water pushing up ∑F = 0 the buoyant force = Fb = density of fluid x g x Volume underwater = density of fluid x g x percent * total volume solve for percentYou need to determine the density of a ceramic statue. If you suspend it from a spring scale, the scale reads 28.4 N. If you then lower the statue into a tub of water so that it is completely submerged, the scale reads 17.0 N. What is the density?
- A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.A 46kg woman wearing shoes with high heels has her weight resting only on an area of 5.5 x 10-³ m² per shoe. a) How much pressure acts on the woman's feet? (both feet!) ✓ ✓ ✓ b) If the woman stood flat footed without high heeled shoes, what affect would it have on the pressure she feels on her feet? Circle one of the following: ✓ a. Increase Pressure b. Decrease Pressure c. No Change in PressureA small statue in the shape of a falcon is painted black and has a weight of 24.1 N. The owner of the statue claims it is made of solid gold. When the statue is completely submerged in a container brimful of water, the weight of the water that spills over the top and into a bucket is 1.25 N. Find the density of the metal. Is the falcon solid gold?
- A scale reads 100 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The mass density of aluminum is 2700 kg/m^3. Be careful, you are given mass density instead of weight density, and we are using SI units.i need answer in problem sigfig3. An object has a weight of 8.10 N when in air.
