When a block of volume 1.27 times 10^-3 m^3 is hung from a spring scale as...
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 wooden block of volume 5.26 times 10^-4 m^3 floats in water, and a small steel object of mass m is placed on top of the block. When m = 0.400 kg, the system is in equilibrium and the top of the wooden block is at the level of the water. (Take the density of steel to be 8 g/cm^3.) (a) What is the density of the wood? kg/m^3 (b) What happens to the block when the steel object is...
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 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
When a large cube is placed in a tub of water, it floats with 0.5 m of it submerged. When the same cube is placed in anunknown liquid, 3.5 m of it is submerged. What is the density of the unknown liquid (in kg/m3)?
A wooden ball with a weight of 16.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 6.00 N. For this problem, we will use a density of water of 1000 kg/m^3, and we will use g = 10.0 m/s^2. If the ball was only 20.0% submerged in water instead, what would the spring scale read? _______ N Part (b) HomeworkUnanswered A wooden ball...
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.
Please Help!!!!! QUESTION 14 A 21 kg block of iron is suspended from a spring with spring constant 118 Nm. tis lowered into a vat of oil density 0.92 g/cm3) and fully submerged. Given that the density of iron is 7.87 g/cm3, how far (in m) is the spring stretched from its rest length? QUESTION 15 A block of yellow pine has a density of 426 kg/m3 and floats in a large tub filled with water (density 1,000 kg/m3) A...
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 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...
