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
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...
A.) An object weighs 70.5 N in air. When it is suspended from a force scale and completely immersed in water the scale reads 15.9 N. Determine the density of the object. B.) When the object is immersed in oil, the force scale reads 47.0 N. Calculate the density of the oil.
7. A solid rock ,suspended in air by a spring scale, has a measured weight of 72 x(# N) newton. When the rock is submerged in water, scale reads 1/3 x(#N) newton. What is a specific density of the rock? Density of water pw=1000 kg/m"; SG= Prock /pw ; B= pw Vg; a) None of these is true b)4.55 c)5.99 d) 1.22 e)2.42
The gravitational force exerted on a solid object is 5.10 N. When the object is suspended from a spring scale and submerged in water, the scale reads 2.50 N (figure). Find the density of the object. Figure (a) shows a vertical spring scale. The top of the scale has a hook attached to the ceiling. The bottom of the scale has a hook attached to a rope. The rope hangs down and is attached to a solid block that hangs...
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.
A block weights 5.50 N when suspended by a spring and weighs 3.6 N when submerged in water and suspended by the same spring scale. What is the density of the block? Scale
A 5.0-kg block suspended from a spring scale is slowly lowered onto a vertical spring (Figure 1) . Part A What does the scale read before the block touches the vertical spring? Part B If the scale reads 34N when the bottom spring is compressed 30 mm, what is k for the bottom spring? Part C How far does the block compress the bottom spring when the scale reads 0? Express your answer with the appropriate units. Enter positive value...
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
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.
