A 1.00-kg beaker containing 2.00 kg of oil (density = 916 kg/m3) rests on a scale. A 1.50-kg block of iron is suspended from a spring scale and is completely submerged in the oil (see figure below). Find the equilibrium readings of both scales.
A solid block is attached to a spring scale. When the block is suspended in air the scale reads 15.0 N; when it is completely immersed in water the scale reads 13.1 N. (a) What is the block's volume? _____ m3 (b) What is the block's density? ______kg/m3
A block of wood has mass of 3.67 kg and a density of 600 kg/m3. It is to be loaded with lead so that it will float in water with 0.90 of its volume immersed. 5. What mass of lead is needed: a) if the lead is on the top of the wood? b) if the lead is on the bottom of the wood?
The mass of a block of metal reads as 0.56-kg when weighed in air. Once the block is completely submerged in water the same spring scale reads 0.21-kg. What is the density of this metal? Please report your answer in kg/m3.
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.
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 block is attached to a spring scale. When the block is suspended in air, the scale reads 20.1 N; when it is completely immersed in water, the scale reads 16.7 N. A.) What is the volume of the block? B.) What is the density of the block?
a piece of aluminum with mass 5.5kg and density 2700kg/m3 is suspended from a string and then completely immersed in a container of water. How many newtons is the tension in the string after metal is immersed?
ISDLVE A beaker of mass 1 kg containing 2 kg 46 of water rests on a scale. A 2-kg block of aluminum (density 2.70 x 103 kg/m2) suspended from a spring scale is sub- merged in the water as in Figure 13-33. Find the readings of both scales. FIGURE 13-33 Problem 46 Aluminum
The mass density of silver at room temperature is 10.5 x 103 kg/m3 and its atomic mass is 108g/mol. If we assume there is one free electron per silver atom, what is the free-electron desity for silver, in electrons/m3? How does this compare to the free electron density of Copper?
