A cube with sides of length 1.50 cm is hung from a scale. The hanging cube is then immersed in water. If the scale reads 0.26 N, what is the density of the cube in kg/m3?
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.
O out of 5 points A steel cube 93 mm on a side weighs 85 N. We want to hold the cube in equilibrium under water by attaching a light foam buoy to it. If the foam weighs 470 N/m what is the minimum required volume in cm of the buoy?
method) 2. (50%) A Carbon Steel Cube (AISI!) of 15 cm per side is at an initial temperature of 100 °C and suddenly immersed in a fluid whose temperature is 50 °C and h 25 W m2 °C, considering a time of one/ teen hour. Calculate: a) the temperature using the concentrated systems method; b) the temperature at the corner of the cube using the method of approaching a term or letters of Heisler, c) The heat transferred. 1010 o,1...
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 cube of wood floats on the surface of a swimming pool. Each side of the cube is 0.25 cm long and the cube has a density of 750 kg m-3 . a.) What fraction of the cube is submerged? b.) If the cube is replaced by one made from another material, what is the maximum allowed density for the new cube to float? c.) The pressure at the bottom of the deep end of the pool is 1.4 x...
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...
An object suspended from a spring scale weighs 0.56 N in air. The same object completely submerged in water and suspended from the same spring scale weighs 0. P(water) = 1 g/ml = 1 g/cm^3 = 1000 kg/m^3 Draw a clearly labeled free body diagram for: i. The mass suspended from the spring balance in air ii. The mass suspended from the the spring balance in water
