Q2. A solid sphere made of metal whose density is 3000 kg/m3,and mass 3.2 kg is suspended by a cord. (a)When the sphere is immersed in water what is the tension in the cord? (b)Now the cord is cut and the sphere is replaced by one of the same size but density 700 kg/m3 . What fraction of the sphere will be below the surface?
A solid aluminum sphere with the density p_n = 2700 kg/m^3 is suspended in air from a scale that reads 13.06N. the sphere is then submerged in a liquid with an unknown density . the scale then reads 8.706 n. work out an expression for the density of the liquid in terms of the quantities and then calculate the density of the liquid.
A board that is 20.0 cm wide, 5.00 cm thick, and 3.00 m long has a density 379 kg/m3. The board is floating partially submerged in water of density 1000 kg/m3. What fraction of the volume of the board is above the surface of the water? 0.379 0.200 zero 0.621 The answer depends on which edge of the board is vertical. A 3.1-kg solid sphere, made of metal whose density is 2500 kg/m3, is suspended by a cord. When the...
A solid metal sphere has a radius of 3.39 cm c m and a mass of 1.877 kg k g . What is the density of the metal in g/cm3 g / c m 3 ? (The volume of sphere is V=43πr3 V = 4 3 π r 3 .)
A 10 kg iron block (density= 7900 kg/m^3) is hanging from the rope. What is the tension in the rope if the block is immersed in a liquid of density 850 kg/m^3?
There is a sphere composed of solid plastic (density = 910 kg/m^3) that is completely submerged underwater. When the sphere is attached to a spring (underwater), the spring is stretched by 0.21m relative to equilibrium length (spring constant, k = 2900 kg/s^2). What is the VOLUME of the marker sphere?
A sphere of cork(density pcork = 240 kg/m^3) is tied to one end of a string and pulled halfway under the surface of seawater(density 1,020 kg/m^3) in a beaker. The other end of the string is tied to the bottom of the beaker. The sphere has a radius of 0.1 m what is the tension in the string
a metal bucket with a height of 0.700 m and a mass of 650 kg is suspended from a rope in an open tank containing a liquid with a density equal to 1530 kg / m ^ 3. The block is submerged 0.300m below the surface. Calculate: A) the upward force at the bottom of the block B) the tension force of the rope C) the magnitude of the buoyant force in the cube using the principle of archimedes String...
The mass density of the solid aluminum cone is 2700 kg/m^3. Determine the weight of the cone in pounds. Dimensions of the cone: h=125 mm; r=75 mm
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)...
