A 400 cm^3 block of aluminum (D=2.7 g/cm^3) is lowered into a completely full beaker of water. What is weight of water that spills out of the beaker? Correct answer is 4N.

When 400 cm^3 block of aluminum is completely lowered in the water, 400 cm^3 of water is spilled out. Its mass is 400 g or 0.4 kg. Find the weight of this water.
The weight of the block when it is lowered into water remains the same as when it is in air. The block's weight is determined by its mass and the force of gravity, which does not change when it is submerged in water.
The weight of the block does not directly affect the amount of water spilled. However, the displacement of the water by the block may cause some water to spill out of the container.
Yes, the shape of the block can affect the amount of water spilled. A block with a larger surface area will displace more water and therefore, more water may spill out of the container.
No, the weight of the water spilled is not equal to the weight of the block. The weight of the water spilled is equivalent to the weight of the water that is displaced by the block.
The density of the block and water do not directly affect the amount of water spilled. However, if the block is less dense than water, it will float and displace a larger volume of water, potentially causing more water to spill out of the container.
