A 5 kg solid cube has sides of length 8.6 cm. What is the density of the cube? answer in SI units of kg/m^3.
An ice cube (density = 900[kg/m3]) with a side length of 2.54[cm] is held by a person so that it is completely submerged within a cupful of water (density = 1000[kg/m3]). What is the buoyant force on the ice cube?
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 vertical scale on a spring balance reads from 0 to 250 N . The scale has a length of 10.5 cm from the 0 to 250 N reading. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.75 Hz . Ignoring the mass of the spring, what is the mass m of the fish?
A block of steel (density of 8.05 x 103 kg/m3) with a mass of 1.50 kg is suspended (in equilibrium) by an ideal spring scale. The block is completely immersed in water (density of 1.00 x 103 kg/m3). What is the reading in the spring scale?
A.) A spring scale hung from the ceiling stretches by 5.3 cm when a 1.4 kg mass is hung from it. The 1.4 kg mass is removed and replaced with a 1.8 kg mass a.)What is the stretch of the spring? B. The mass in a pendulum clock completes one complete swing in 1.20 s . a.)What is the length of the rod?
A spring is hanging from the ceiling. When a 2 kg mass is hung from the spring, the spring has a total length of 50 cm. When a 5 kg mass is hung from the spring, the spring has a total length of 70 cm. Determine the spring's relaxed length and its spring's spring constant. (You should keep 4 decimals in your values to avoid rounding errors.)
When a block of volume 1.27 times 10^-3 m^3 is hung from a spring scale as shown in Figure A. the scale reads 9.0 N. When the same block is then placed in an unknown liquid it floats with 2/3 of its volume submerged as suggested in Figure B. The density of water is 1.00 times 10^3 kg/m^3. Determine the mass of the block. Determine the density of the unknown liquid.
A 10-kg mass hanging from a spring whose equilibrium length is 20 cm stretches it by 4.0 cm. A fish is then hung from the same spring and stretches if by 3.0 cm. Find: A) What is the weight of the fish? B) How long would the spring be stretched if the mass and the fish were hung together from the same spring?
A 5.0kg cube of metal has a density of 3000 kg m3 and is held by a vertical string while immersed in water which has a density of 1000 kg m3 . Assume that the cube is oriented so that all the faces are either vertical or horizontal. a) What is the length of each side of the cube? (b) What is the difference in pressure between the top of the cube and the bottom? (c) What are the vertical...
