It is caused by the difference in density between wood and water.
One cubic foot of wood is usually lighter than one cubic foot of water, hence the water goes up a little but the wood goes up more.
The overall density of the wood block is less than that of the water, so it floats.
The basic principle is that when a solid object is immersed in a fluid, the solid displaces some of the fluid. This causes an upthrust on the solid, equal to the weight of fluid displaced. If the upthrust is equal to the weight of the solid it floats.

The force of buoyancy, which is the upward force exerted by a fluid on an object immersed in it, keeps a piece of wood floating. This force is equal to the weight of the fluid displaced by the object, allowing the wood to stay afloat as long as its weight is less than the weight of the fluid it displaces.

What is the buoyant force on a 30 lb block of wood floating in a lake?
The buoyant force on the block of wood is equal to the weight of the water displaced by the block, which is 30 lb. This is because the block is in equilibrium, with its weight equal to the buoyant force pushing it up.

What type of energy is used to cut a piece of wood?
Mechanical energy is used when cutting a piece of wood. This energy is created by the force applied to the cutting tool, such as a saw or axe, which ultimately breaks the chemical bonds in the wood fibers to separate the pieces.
What is the apparent weight of the floating block when a block of wood is floating in a lake?
Zero.
When twisting a screw into a piece of wood where is the input force applied and where is the ouput force exerted?
The input force is applied at the head of the screw when twisting it. The output force is exerted through the threads of the screw against the wood, holding it in place.
What is the buoyant force on a 30 lb block of wood floating in a lake?
The buoyant force on the block of wood is equal to the weight of the water displaced by the block, which is 30 lb. This is because the block is in equilibrium, with its weight equal to the buoyant force pushing it up.

What tools do you need to set up a floating shelf?
For a do-it-yourself floating shelf, the minimal requirements are a precut piece of wood (or a saw to cut the wood), a hammer and nails. Premade or precut floating shelves purchased at retail stores often come with at least some tools included.
Give the effects of buoyant force of liquids on solids less dense than the liquids?
See if the solid is less dense than the liquid, like a cork floating on water or a log of wood floating on the water. The buoyant force acts on the cork or the wood and overcomes the force exerted due to acceleration due to gravity because of which these things float.
What is the difference between Bamboo floors vs floating floors?
There are three types of wood flooring: solid, engineered, engineered floating. Solid is natural wood usually 3/4" thick. Engineered is solid piece of wood on top of compressed wood the wood is usually 1/4" thick and the compressed wood is anywhere from 1/4" to 1/2" thick. Engineered floating is thin solid piece of wood on top of compressed wood, it is thin enough so during installation it does not have to be attached to the subfloor. The solid wood is usually about 1/8" thick and the compressed is 1/4" thick. All these three types come in all different types of wood species such as bamboo.
When you use a hammer to drive a nail into a piece of wood are you changing the size or the direction of the force?
change the direction of force,because it exerted the force on it.
Why a piece of wood left under water come to the surface?
Wood floats in water because it is less dense than water. However, when a piece of wood is submerged for a long time, it can become waterlogged, making it denser and causing it to sink. As the water evaporates from the wood, it becomes less dense again and returns to the surface.
A piece of iron on top of a piece wood floating in a bathtub If the iron is removed from the wood what happens to the water level in the tub?
The water level will go down slightly when the iron is removed from the wood, as the iron displaces more water than the same volume of wood. When the iron is removed, the water that was displaced by the iron will return to the tub, causing a small decrease in water level.
What is the apparent weight of the floating block when a block of wood is floating in a lake?
Zero.
What is the density of a piece of wood?
It depends of the piece of wood itself and the type of wood that it is.
Why can't Jack and Rose be together after the Titanic crashed?
Because Jack died in the cold water while Rose was laying safely on top of a floating piece of wood.
