What force is needed to keep a wooden block of density 720 kg and volume 1.0 m3 under water?
Using the rough rule-of-thumb: 1 liter of water = 1 kg.
-- The block sinks until it has displaced 720 liters of water. At that point,
the mass of the displaced water has the same weight as the mass of the
block has, and the block sinks no further.
-- The block still has 280 liters of its volume above water. If that were submerged,
another 280 kg of water would be displaced.
-- The additional 280 kg of water would weigh (280 x 9.8) = 2,744 newtons (617.3 pounds).
That much additional buoyant force would fight the effort to submerge the block.
It takes an additional 2,744 newtons (617.3 pounds) to keep the block under water.
What else can I help you with?
What will happen to the mass volume and density if you chop the wooden block in half?
The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.
What is the density of a rectangular block?
It is the mass of the block divided by its volume.
How is the mass of a wood block related to its volume?
Density of wood = mass/volume
How do you find the density of a block of wood?
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
If you cut a wooden block in half each have will have?
If you cut a wooden block in half, each half will have the same volume and mass as the other, assuming a uniform density throughout the block. The surface area of each half will increase, and they will each retain the same material properties as the original block. However, any features like grain patterns or defects will be split between the two halves.
How you would use a triple beam balance and a ruler to find the density of the solid a wooden block?
Density (kg/m3) = mass (kg)/Volume (m3) So to find the density of the wooden block, the triple beam balanced is used to calculate the mass and the metre rule is used to measure the height, length and width of the wooden block. Then the volume is calculated by multiplying the thee distances obtained from the ruler. Finally the density is calculated using the equation: Density (kg/m3) = mass (kg)/Volume (m3)
What will happen to the mass volume and density if you chop the wooden block in half?
The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.
A wooden block has a mass of 1000 kg an a volume of 2 cubic meters What is the blocks density?
1000 kg/ 2 m3 = 500 kg per cubic meter density or 0.5 g/cm3 or approximately half the density of water
How do you find the density of a block?
it is easy. You use Mass divided by Volume. You can Remember it by a heart. The top is a M and the bottom is a V. Mass divided by volume. <3
What is the density of a block of wood with a mass of 120g and a volume of 200cm cubed?
The density of the block of wood is 0.6 g/cm^3. (Density = mass/volume)
What is the density of a rectangular block?
It is the mass of the block divided by its volume.
What is the density of a block of wood that has a volume of ml and a mass of g?
To calculate the density of the block of wood, you would divide its mass (in grams) by its volume (in milliliters). The formula for density is: Density = Mass / Volume. Plug in the values for mass and volume to find the density of the block in g/mL.
What is the density of a wood block with a volume 125 cm3 and a mass of 57g?
The density of the wood block is calculated by dividing the mass by the volume, so density = mass/volume. In this case, density = 57g / 125 cm3 = 0.456 g/cm3.
What is The mass of a block of stone is 3000 kg if the block has a volume of 1.5 M squared what is its density?
To calculate the density of the block of stone, use the formula: density = mass/volume. Given that the mass is 3000 kg and the volume is 1.5 m³, the density is 3000 kg / 1.5 m³ = 2000 kg/m³. Therefore, the density of the block is 2000 kg/m³.
Which two tools would help you determine the density of a block?
To determine the density of a block, you can use a balance to measure its mass and a ruler to measure its dimensions. The density of the block can then be calculated by dividing the mass by the volume.
What physical properties of a wooden block is it density related to how could density be used to identify another sample of wood?
The density of a wooden block is related to its mass and volume. Two blocks made of different types of wood will have different densities due to variations in their composition. By measuring the mass and volume of a sample of wood and calculating its density, you can compare it with known values for different types of wood to identify the sample.
What is the density of a block 384kg volume 4096cm?
4096 cm is not a volume, but a length. Once you know the volume, divide the mass by the volume to get the density.
