It is easier to lift a metal block or massive stone underwater because buoyancy helps to support some of the weight of the object. The water exerts an upward force on the object, reducing the effective weight that needs to be lifted by the person. In contrast, in air, there is no buoyant force to counteract the weight of the object, making it feel heavier to lift.

What is a bending block?
A bending block is a tool used in metalworking to shape metal by hammering or pressing it over the block's curved or angled surface. It helps to create precise bends in the metal without causing damage or distortion.
How defects in a metal block can be detected using ultrasound?
The ultrasound waves are allowed to pass through metal block to which are fitted detectors to detect the waves. If the metal block has a very small defect, such as an air bubble or a crack, then the ultrasound waves are reflected from such spots. The reflected ultrasonic waves indicates that metal block is defective.
What can block microwaves from penetrating through objects?
Metal objects can block microwaves from penetrating through other objects.
What does the gavel rest on.?
The gavel typically rests on a sound block, which is a small wooden or metal piece used to enhance the sound when the gavel strikes it. The sound block helps amplify the noise created by the gavel, making it easier for the presiding officer to call for order or announce a decision during a meeting or court proceeding.
What could you decrease the thermal energy of a metal block?
You can decrease the thermal energy of a metal block by allowing it to cool in a cooler environment, such as placing it in contact with a cooler surface or exposing it to a colder surrounding. Alternatively, you can reduce its thermal energy by transferring heat away from the metal block through a process like conduction or convection.
What is metal block in workshop?
a block of metal
What is another word for heavy metal block?
What is a word for a heavy metal block
A block of metal is attracted to a magnet What must the block contain?
if a block of metal is attracted to a magnet it must have flowing charged particles (electrons)
What is dry-liners?
In a dry liner the coolant runs in channels in the block, and the liner is only like a sleeve stuck in a metal hole. Poorer cooling, but an easier build.
Is maganese a nonmetal metal or a metalloid?
Manganese is a metal. It belongs to d block and is a transition metal element
What are the good metal in s block element?
a metal element
What is the density of a metal block hat has a mass of 750g and a volume of 55cm3?
The metal block's density is about 13.636 g/cm3
Is zinc a base metal?
Yes. It is a metal. In periodic table all the elements in s block (except hydrogen), d block and f block elements are classified as metals. And if you precisely ask if it is a base metal, you have to mention the alloy name. i
What is the mass of a metal block?
The mass of a metal block can vary depending on its size and composition. To determine the mass of a metal block, you would typically weigh it using a scale. The mass would be measured in units such as grams or kilograms.
Why does heating a metal make it easier to shape?
Heating a metal makes it easier to shape because it increases the metal's ductility and reduces its hardness. This allows the metal atoms to move more freely and rearrange their positions, making it easier to deform the metal without it breaking.
Why Li is metal?
It is a s block element. It is making a metal bond.
Is Platinum a metal or non-metals or metaloid?
Platinum is a metal. It is in the p block.
