What part of the block of wood remains immersed in water of density 1000kg per cm cube when the block of wood placed in water has density 700 Kg per m cube?
Preranajoshi98
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water.
-- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced
its entire weight in water, and floats.
-- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.

How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
If object has mass of 3.5gml is placed in water what will happen?
I think you mean to say density. If I'm right, it'll sink.
How did Archimedes solve the King's problem?
He discovered the difference in density between gold and silver when placed under water, and noticed that the crown was not pure gold. The crowns maker was later beheaded.
Another word used for placed?
Situated, Located, Positioned, Set, Placed, Sited, Found
What would happen if a substance with a density of 0.95gml was placed in oil?
That would depend upon the density of the oil (which will depend upon temperature), how absorbant of oil the substance was and how deep the oil is. Assuming the substance does not absorb any of the oil then depending upon the oil various things would happen: In some oils such as Car oils, Coconut oil, Crude oil California, Linseed oil which all have a density less than 0.95 g/ml the substance would sink (unless the oil was not deep enough in which case the substance would sit on the bottom of the container and appear above the surface of the oil). In other oils such as Castor oil, Crude oil Mexican, Rosin oil which all have a density greater than 0.95g/ml the substance would float.
Does the tendency for an object to sink or float have to do with the object's density?
Yes. The object will sink if its density is greater than the fluid it is placed in.
What is the density of an object with a mass of 5g that when placed in a graduated cylinder raises the volume of water from 30mL to 45mL?
If the object is fully immersed then density is (5)/(45-30) = 5/15 = 1/3 gm per mL (and since it is less than 1 the density of water, is it fully immersed without something holding it down?)
What happens if you placed an insulator in an electric field?
You would then have an insulator immersed in an electric field. Nothing would happen.
Why does anything sink?
An item will sink if its overall density is greater that the density of the fluid in which it is placed
What effect does the density of liquid have on the buoyancy of an object?
An object with lower density than the liquid will float, one with more density will sink. Anything with the same density will stay at the depth where it is placed. If it is placed half submerged it would sink until submerged.
Would the density of white oak sink or float if it is placed in water?
The density of the wood would not be affected by being placed in water. However, the wood itself, with a density of about 0.77 gm/cm3 , would float.
WHAT happens to a solid object with a density that is less than the density of water when it is placed in water?
It floats
Is buoyancy and density the same?
An object with greater density than the liquid it is placed will tend to sink
An object most likely sink in water if it has low density?
The lower an objects density the less likely it is to sink in water. Objects with a higher density than water will sink if placed in it while objects with a lower density than water will float if placed in it.
How does density affect the floating and sinking of objects?
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
How much does the density have to be for something to sink?
Answer: More than 1.0 Answer: More than the density of the liquid in which the object is placed. For example, water has a density of about 1000 kg/m3; any object with a greater density than this will sink if placed in water. If you place something in oil, the numbers are different.
Why do objects sink when placed in water?
Only objects having a density higher than the density of a liquid sink.
