A solid sphere of mass 9.4 kg, made of metal whose density is 4400 kg/m^3, hangs by a cord. When the sphere is immersed in a liquid of unknown density, the tension in the cord is 43 N. The density of the liquid is closest to which one of the following values? A) 2200 kg/m^3 B) None of the Choices C) 2000 kg/m^3 D) 1900 kg/m^3 E) 2300 kg/m^3 F) 1700 kg/m^3
A 6.0 kg iron block is suspended from a spring scale and is submerged in a fluid of unknown density. The spring scale reads 3.0 N. What is the density of the fluid? The desity of iron is 7. 80 × 103 kg/m3.
P1. (10 points) A rock is suspended from a scale that reads 20.0 N (in air). A beaker of water (having a density of 1000 kg/m3) is raised up so the rock is totally submerged in the water. The scale now reads 12.5 N. What is the density of the material of rock?
The gravitational force exerted on a solid object is 5.80 N. When the object is suspended from a spring scale and submerged in water, the scale reads 2.40 N (figure). Find the density of the object. kg/m3
4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...
The gravitational force exerted on a solid object is 4.70 N. When the object is suspended from a spring scale and submerged in water, the scale reads 2.70 N (figure). Find the density of the object. .000204 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. kg/m
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?
