object submerged in water?

a) F = ma\n    F = 0.0412 kg * 9.8m/s^2\n    F = 0.404 N\n\nb) F = 0.0370 kg * 9.8 m/s^2\n    F = 0.363 N\n\nc) The difference in "weight" is equivalent the weight of the displaced volume of water...  So...\n   0.404N - 0.363N = V * 1000 kg/m^3 * 9.8 m/s^2\n   0.041N = V * 9800N/m^3\n   V = 4.18 * 10^-6 m^3   or  4.18 cm^3\n\nd) Oh Juliet you are my density.... (bad joke!)\n     Density = m/V\n     D = 0.0412 kg / 4.18  * 10^-6 m^3\n     D = 9848 kg/m^3

First find the volume of the object, i.e metal, by placing it in water and then u know the amount of water displaced.\nIf it displaces half the water than it's weight, then u know that it's specific gravity is twice that of water.

It all depends on buoyancy and density. \n\nIf the weight of an object is less than the weight of the fluid the object would displace if it was fully submerged, then the object is less dense than the fluid and it floats at a level so it displaces the same weight of fluid as the weight of the object.\n\nIf the object has exactly the same density as the liquid, then it will stay still, neither sinking nor floating upwards, just as the liquid nearby stays still.\n\nUNLESS, \n\nAn object made of a material of higher density than the fluid, for example a metal object in water, can still float if it has a suitable shape (ex: hollow) that keeps a large enough volume of air below the surface level of the fluid. In that case, for the average density mentioned above, the air is included also, which may reduce this density to less than that of the fluid.

Water is not wet, it makes things wet!

You have contact dermatitis. You are getting an allergic reaction to something in the water. In fact this is an improper immune response.

it's a mixture of air and water. when the waves are churning up they mix in air and the combination is what you see as foam. also some minor impurities are present.

It's a form of underwater swimming

It probably is evaporating from the top. The bubbles on bottom are just more visible.

The water level will go down when you throw the body in.  Try it in your sink.  Fill your sink with water and float a bowl (boat) in it.  Then, fill the bowl with silver wear (body and rocks) or anything more dense than water.  Mark where the water level is on the side of the sink.  Now, take the silver wear out, and put it in the water so it falls to the bottom of the sink.  You will notice that the water level went down.  When the silver was in the bowl, it displaced much more water than when it was at the bottom of the sink.  Therefore, the body will displace more water when it is inside the boat than when it falls into the water.

water was being taken but not put back!?

there is salt in the water

It may be surface tension.

Bubbles form from the dissolved gases in the water.

Archimedes said: When an object is submerged in water, there is a buoyant force upwards on it that is equivalent to the weight of the water displaced. \n\nSo if you have a heavy object underwater, and it is displacing water, its net weight will be less than when it is in air, displacing air, which is much lighter, so has a much smaller buoyant effect.
