2) Cotton 3) Can't say
4) Equal​

Answer 1

Answer:

cotton

Explanation:

Upthrust will be more for the cotton as it will have a larger surface area per unit of apparent weight due to the lower density. So every 1 kg apparent weight is somewhere near 1.1 kg actual weight of cotton. And 1kg Iron actually weighs near 1.09 Kg. Therefore, Cotton is heavier!
