The amount of water displaced by the block is the volume of the block. so (volume of water with block in it)-(original volume of water)= volume of block
As the mechanical advantage increases, the length of the string you have to pull decreases. This is because a higher mechanical advantage means that the force you apply is amplified, requiring you to move the string a shorter distance to lift the block.
As the angle of the incline increases, the normal force (support force) decreases. The normal force is perpendicular to the surface, and as the incline becomes steeper, more of the gravitational force acts parallel to the incline, reducing the normal force required to keep the block in equilibrium.
As iron is heated, the movement of molecules inside the solid block of iron increases, leading to greater vibration and kinetic energy. This causes the atoms and molecules to move more freely within the lattice structure of the solid, resulting in expansion of the iron block.
It will not affect mass because the mass of an object stays the same (unless you take away or add mass). It will affect volume and density. Since the object is being flattened so it takes up less space, its volume is smaller. But since it is the same amount of matter just in a smaller space, the density is greater. Basically, volume and density are inversely related (in respect to mass). With mass staying the same, as the volume decreases, the density increases.
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
A pulley block system increases mechanical advantage by using multiple pulleys to distribute the weight of a heavy object. As the number of pulleys increases, the force needed to lift the object decreases, making it easier to lift heavy objects.
Nothing happens to the density. It's a property of the <substance>. The density is the same regardless of how large a piece you have. That's why density is a useful concept. It tells you something that's true of the <substance> regardless of what size sample you're holding. A large block of ice has the same density as a small ice cube. The 49¢ sample of Acme soap has the same density as the $1.49 family-size bar of Acme soap.
When work is done on a sliding block with friction, it can either increase or decrease the block's potential energy, depending on the direction of the force applied. If the work is done against the force of friction, the potential energy of the block increases. Conversely, if the work is done in the direction of the force of friction, the potential energy of the block decreases.
To find the volume of a block, multiply the length, width, and height of the block together. The formula for volume of a block is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the block.
It depends on the block! Not all blocks are the same shape nor volume.
