An ice cube measures 10 cm on the side, and floats in water. One cm extends above the water level. If you shave off the 4 cm above the water, how many cm of the remaining ice would extend above water level? Answer in units of cm.

An ice cube floats in a beaker of ice cold water. Since the water is ice cold, the ice cube is not melting and hence its volume is not changing. The density of water and ice are, respectively, ρw = 1,000 kg/m3 and ρi = 917 kg/m3. (Assume one of the ice cube's faces is parallel to the water's surface.) (a) If the ice cube is 17.0 mm on each side, how far below the surface (in mm) is the...
A large ice cube floats in a glass of water.
There is a steel bolt frozen inside the ice cube. What happens to
the water level when all the ice melts? (No water is lost due to
evaporation.)
The water level will rise.
Without knowing the mass of the bolt, we cannot answer this
question.
The water level will fall.
The water level will not change.

A cube of wood 20cm on each side floats in water so that 7cm is above the surface of the water and 13cm is below. a)What is the density of the wood? ( You must justify your answer) b) How much force would have to be exerted on the wood to submerge it? c) what volume of lead mass has to be placed on top of the block of wood so that it will just be totally submerged? d)Suppose a...
A 200 gram ice cube floats in water, 92% submerged. What is the magnitude of the buoyancy force that the water exerts on the ice cube? Please show all math steps and how you decided on the formula to use to solve the question. Thanks!
a cube of wood 30 cm on a side and having a density of 0.65 g/cm^3 floats on water. A) what is the distance from the top of the cube to the water level? B) how much lead weight has to be placed on top of the cube so that its top is just level with the water?
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...
Consider a large cube of ice floating in seawater. The specific gravities of ice and seawater are 0.92 and 1.025 respectively. If a 10 cm high portion of the cube extends above the surface of the water, determine the height of the ice block below the surface.
QULIOL DI LUMILLI ILJ Oil 28% 10 cm (a) A cube of side length 10.0 cm and made of an unknown materials floats at the interface between water and oil. The oil has a density of 810 kgm . Cube floats so that it is 72% in the water and 28% in the oil. Calculate the mass of the cube and the buoyant force on the cube. 72% Water 10 cm A firehose with a diameter of 70 mm is...
A cube of water 11 cm on a side is placed in a microwave beam having Eo = 14 kV/m. The microwaves illuminate one face of the cube, and the water absorbs 86 % of the incident energy Part A How long will it take to raise the water temperature by 50 °C? Assume that the water has no heat loss during this time. Express your answer to two significant figures and include the appropriate units. t= Value Units Submit...
