Y is it that none is heavier

If you're asking why objects that are equal in weight don't have one that is heavier than the other, the answer is that they have the same weight. If two objects have the same weight, they will not have one that is heavier than the other. This is because weight is a measure of the force of gravity acting on the mass of an object. If two objects have the same mass and are subjected to the same amount of gravity, they will have the same weight.

I'm not sure what you mean by "Y is it that none is heavier". Could you please give me more context or information so that I can better understand and provide a helpful response?

Why is it that none of them heavier than the other because I thought

The statement that "none is heavier" implies that there is a group of objects or individuals, and none of them weighs more than the others. This can be explained by considering two different scenarios:

1. Equal weights: If all the objects or individuals in question have the same weight, then none of them would be considered heavier than the others. This scenario could arise if the objects are intentionally manufactured to have equal weights or if the individuals in question have similar body compositions.

2. Insufficient information: Another possibility is that we don't have enough information to determine which object or individual is heavier. It could be that we haven't measured their weights or observed any differences in their appearances that could indicate differences in weight. In such cases, without any definitive evidence, we cannot conclude that any of them is heavier than the others.

If you're referring to a specific situation or context, providing more details would allow for a more specific answer.
