The mass of an object is a measure of the amount of matter it contains and it remains constant regardless of where the object is located. If both the bag of cotton and the iron bar are measured to be 100 kg on a weighing machine, it means they both contain the same amount of matter. Therefore, neither is heavier than the other in terms of mass.
However, if we consider the volume they occupy, the bag of cotton will be much larger than the iron bar because cotton is much less dense than iron. This is why a bag of cotton appears to be lighter when you lift it, even though its mass is the same as that of the iron bar. The perceived weight is less because of the larger surface area over which the weight is distributed. But in reality, if both have the same mass, they are equal in weight.
So, in conclusion, neither the bag of cotton nor the iron bar is heavier than the other if they both have a mass of 100 kg. The difference lies in their volume and density.
Answer: The paradox is designed to be self-contradictory, and there isn't a straightforward answer within the given context
Explanation: This scenario is a classic example of a paradox known as the "Barber Paradox" or the "Weight Paradox." It's a type of self-referential paradox. Here's how the paradox is structured:
1. **Assumption:** Suppose the bag of cotton and the iron bar each indicate a mass of 100 kg on a weighing machine.
2. **Paradoxical Question:** Which one is actually heavier?
3. **Paradox Explanation:** If the bag of cotton is heavier, then its indicated mass on the weighing machine is correct, but that would mean the iron bar is lighter than indicated, contradicting the assumption. On the other hand, if the iron bar is heavier, then its indicated mass is correct, but that would mean the bag of cotton is lighter than indicated, again contradicting the assumption.
This paradox highlights the logical issues that can arise when dealing with self-reference and paradoxes. In reality, there is no inconsistency; it's a thought experiment designed to illustrate how self-reference can lead to logical contradictions. The paradox plays on our expectations based on the assumption and challenges us to think critically about the implications.
