What is the mass density (g/cm^3) of a 450g block that displaces 200 cc of water
A block is 5 cm X 7 cm X 2cm and has a mass of 128 g. If the density of water is 1 g/cc what is the apparant mass for the block once its submerged in Water? A. 58 g B. 70 g C. 140 g
In the figure, an aluminum wire, of length L1-1.26x103 cm, cross-sectional area 1.00x102 cm2, and density 2.60 g/cm3, is joined to a steel wire of density 7.80 g/cm3 and the same cross-sectional area. The compound wire, loaded with a block of mass m 5.00 kg, is arranged so that the distance from the joint to the supporting pulley is L2 1.09x103 cm Transverse waves are set up on the wire by an external source of variable frequency; a node is...
A particular cylindrical bucket has a height of 50.0 cm, and the radius of its circular cross-section is 15 cm. The bucket is empty, aside from containing air. The bucket is then inverted so that its open end is down and, being careful not to lose any of the air trapped inside, the bucket is lowered below the surface of a fresh-water lake so the water-air interface in the bucket is 40.0 m below the surface of the lake. To...
A piece of steel is 15.0 cm long and has a cross-sectional area of 2.00 cm by 3.00 cm. If a 50.0 kg mass is suspended from it, by how much will it stretch?
11. An aluminum wire with a square cross-section 2 mm on a side is carrying a current of 1.5 amps. Aluminum has a resistivity of 2.69 x 10* ohm-cm and an atormic volume of 10 cc/mol. Assuming aluminum has three free electrons per atom, calculate the (a) Hall coeffcient, (b) electron mobility, (c) drift velocity, d) collision time. (e) electric field, (f) power dissipated (heat generated) per cm length, and (g) the Hall voltage across the wire in a transverse...
A liquid_p = 1.45 g/cm^2) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm^2, the flow speed is 248 cm/s, and the pressure is 1.20 times 10^5 Pa. In the second section, the cross-sectional area is 4.50 cm^2. Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.) m/s Calculate the smaller section's pressure. Pa Whole blood has a surface...
72. A rectangular block has dimensions 2.9 cm X 3.5 cm X 10.0 cm. The mass of the block is 615.0 g. What are the vol- ume and density of the block?
QUESTION 3 [10 marks] A block of wood 30 cm square in cross section and 60 cm long weighs 318 N. Determine whether the wood is stable in water and find out if the wood will float. 30 cm-| 60 cm- 30 cm End view Side view
A) A 4.00 cm x 4.00 cm x 4.00 cm cube of density 920 kg/m3 is floating at rest at the top of a beaker of cross sectional area 100 cm2 with 500 mL of water in it (1 mL of water has a volume of 1 cm3 or 1x10-6 m3 ). 500 mL of oil of density 900 kg/m3 is added to the top of the beaker, and the cube is observed to float completely submerged, unevenly straddling the...
