Iron is denser than copper, so a block of iron will displace more water than a block of copper of the same weight because the iron block takes up less space for the same mass. This means that the iron block will sink deeper into the water, displacing more water.
This is a factor of many things, for example, the weight of the iron and the wood, the dimensions of the container and how much water there is, but generally the water will rise because if the item is on top of the water displaces its weight in water.
The weight of an iron nail may increase slightly after 3 days in salt water due to the absorption of some water and formation of rust on its surface, which adds weight. Additionally, the salt in the water can also contribute to the corrosion process.
Actually it doesn't affect its weight at all. During the chemical change that occurs when iron rusts, the weight does not change because weight never changes during a chemical reaction because nothing new is being created nor destroyed, only combined.
The molecular weight of iron (Fe) is approximately 55.85 grams per mole.

Both 10kg of cotton and 10kg of iron weigh the same, as they both have a mass of 10kg. The difference in the amount of space each material occupies may make it seem like one weighs more than the other, but in terms of weight, they are equal.
The aluminum block will experience a greater buoyant force compared to the iron block because aluminum is less dense than iron, making it more buoyant in water. The buoyant force is equal to the weight of the water displaced by the object, so the lighter aluminum block displaces more water and experiences a stronger upward force.
You need to learn how to type, it makes u look like a retard
A block of iron sinks because its density is greater than that of water, meaning it displaces less water than its own weight. In contrast, an iron boat floats because its overall design includes a hollow structure that increases its volume and reduces the average density of the entire object, allowing it to displace enough water to counterbalance its weight. This principle is rooted in Archimedes' principle of buoyancy.
Aluminum block weight- 120lbs iron block- 204lbs
There's no reason to say that it always does that. It only does if it has more volumethan the copper block. If the copper block has more volume, then it displaces morewater than the iron block does.In fact, if you get a styrofoam block that's big enough, that can displace more waterthan your iron block OR your copper block. It just has to be big enough.
Randomly, probably not but not due to there weight but manufacturing.
Well it will be where the wright of the overhang rod equals the weight of the rod plus the weight of the 10kg so we have 60kg total weight we will need 30 on each side so you will have 30kg of the rod weight on one side of the balance and 20 rod and 10 of the weight on the other so you have 20/50th or 2/5th of the rod weight on the side with the weight so 6m=2/5th * L where L is the length of the rod so 6*5/2=L or the rod is 15m long.
Archimedes discovered that... "An object in a fluid experiences an upward force equal to the weight of the fluid displaced by the object." The story is that Archimedes discovered displacement when he jumped in a bath and the bath overflowed. He found that the amount of water that overflowed was exactly equal to the volume of his body. It was the original "Eureka!" moment. So... If the volume of a boat displaces more weight of the water it is in than the total weight of the hull then the boat will float. A block of iron won't displace more weight of water than the block weighs, so it will sink.
Earth's gravity pulls equally on both a block of wood and a block of iron of the same size. Gravity depends on the mass of the objects, not their material composition. The weight experienced by each block will be based on their mass, with the iron block likely to be heavier due to its higher density.
That depends on how much of it you're trying to carry in the water. Whatever size lump of iron you have, its weight will decrease by about 12.7% when you get it into the water. That means whatever amount of iron you can lift, you'd be able to manage about 14.5% more if the iron was in water.
