Question 1 A crane is used to lower weights into a lake for an underwater construction project. Determine the tension in the rope of the crane due to a Im-diameter spherical steel block (density 88.005 g/cm²) when it is (a) suspended in the air and (b) completely immersed in water.
A crane is used to lower weights into a lake for an underwater construction project. Determine the tension in the rope of the crane due to a 1m-diameter spherical steel block (density 88.005 g/cm3 ) when it is (a) suspended in the air and (b) completely immersed in water. Please write Clearly
Hydrostatic weighing, or "underwater weighing," is used to measure a patient's body composition. To do this measurement, the patient is weighed while standing on a regular scale and then weighed while immersed in water. By comparing these weights, the density and body fat percentage of a patient can be recorded. The weight of your patient on a regular scale is 610 Nand while immersed in water is 90 N. The density of water is 1000 kg/m3 and assume that g...
The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water. The density of seawater is 1025 kg/m3. (a) If an underwater vehicle were to explore such a depth, what force would the water exert on the vehicle's observation window (radius = 0.294 m)? (b) For comparison, determine the weight of a jetliner whose mass is 3.17 × 105 kg
Question 3 (a) (i) A sealed lightweight plastic cube of sides 0.75m is submerged under water, as shown in Figure Q3a. Find the net hydrostatic forces acting on the cube. [8] (ii) If the cube is lowered further in the water, what effect does this have on the hydrostatic forces? (iii) If the cube must be maintained in the location shown in Figure Q3a using a rope tied to a concrete block, what volume of concrete is required? [1] (Note:...
1. An undersea research chamber is spherical with an external diameter of 5.60 m. The mass of the chamber, when occupied, is 68400 kg. It is anchored to the sea bottom by a cable. The density of sea water is 1025 kg/m3. Calculate the following: (express your answers using appropriate mks units.) (a) the buoyant force on the chamber (b) the tension in the cable 2. A green brass block is placed on top of a 0.17 kg yellow styrofoam...
1. ***present all the calculations*** Part I: The density of seawater is approximately 1.027g / cm3 and the ice density 0.93g / cm3. United Nations Iceberg (iceberg), generally has a mass of 150,000 metric tons (1 metric ton = 1000kg). Calculation (a) The buoyant force exerted by the water on the "iceberg", (b) the volume of the iceberg above sea level, (c) the volume fraction above sea level. Part II: A metal bucket with a height of 0.700 m and...
What is the total force acting on the outside of the spherical submarine of diameter 2.0 m when it is 1000 m below the surface of the ocean? The pressure inside is 1.0 ATM and the density of seawater is 1020 kg / m3
(1 point) Viewing Window The underwater viewing window of a dolphin aquarium is rectangular and has a width W 15 m (into the page), height H 3 m, and thickness t. The window is located such that its top edge is h = 15 m below the water surface. As a poor design choice, the window is bonded to the walls of the aquarium along its top, bottom, and side surfaces (all surfaces except the two that are necessary for...
) The back of a frog has a surface area of 0.0052 m2. If the frog is on land at sea level, how much force will the frog’s back feel from air? The frog swims to a depth of 0.45 m in freshwater. What is the total pressure (from air + water) that the frog will feel on its back at that depth? If the frog instead was swimming in saltwater, which has a density of 1025 kg/m3, what depth...
