A wooden raft has a mass of 100.0 kg. When empty it floats in water (density of 1000 kg/m3 ) with 40% of its volume submerged. How many students of mass 75 kg each can stand on the raft without it sinking?
When a 122.4kg chest is placed on the raft, the raft floats with its top surface 20cm above the water(10 cm is under water). The density of the water is 1077 kg/m^3 What is the mass of just the raft? How strong it the buoyant force being exerted by the water on the raft? How many crates can the raft hold (including the on on it)? 30m I poom
A barge floating in fresh water (p=1000 kg/m3) is shaped like a hollow rectangular prism with base area A=450 m2 and height H=2.0 m. When empty the bottom of the barge is located H0=0.55 m below the surface of the water. When fully loaded with coal the bottom of the barge is located H1 = 1.4 m below the surfacePart (a) Find the mass of the coal in kilograms. Part (b) How far would the barge be submerged (in meters) if...
A U-tube contains liquid of unknown density. An oil of density 770 kg/m³ is poured into one arm of the tube until the oil column is 13.5 cm high. The oil-air interface is then 4.5 cm above the liquid level in the other arm of the U-tube. Find the density of the liquid. A raft is made of 11 logs lashed together. Each is 38.0 cm in diameter and has a length of 7.00 m. How many people (whole number)...
A cube of wood having an edge dimension of 18.1 cm and a density of 655 kg/m floats on water. (a) What is the distance from the horizontal top surface of the cube to the water level? This is the length of the edge of the wood block that lies below the surface. cm (b) What mass of lead should be placed on the cube so that the top of the cube will be just level with the water surface?...
The sperm whale can dive to a depth of 2250 meters. For sea water with a density of 1020 kg/m3 what is the difference in pressure at this depth as compared to the surface? Supply your answer in atmospheres" (atm), where 1 atm approximately equals 1x105 Pa. (This is an incredibly large pressure. Human bodies would be crushed. The deepest human dive recorded was around 300 m, and even then, the diver had to spend 12 hours to surface from...
19) A 22.0-kg mirror with a surface area of 1.0 m2 and a 98% reflectivity is bombarded by light of average intensity 770.0 W/m2 at an angle of 30.0° to the normal of its surface. If the light has a duration of 0.60 s, how much does the velocity of the mirror change during that time? (c = 3.00 × 108 m/s, uo = 41 * 10-7 T.m/A, €0 = 8.85 x 10-12 C2/N·m2)
