Question

A block of cork, a block of wood, and a block of metal are all placed into 3

Answer 1

Answer:

Cork: Less

Wood: About the same

Metal: More dense

Step-by-step explanation:

Whether or not a block floats inside water is dependent on its density. If it is floating, it means it has a lower density. If it is sinking, it means it has a higher density. If it has the same, it will be half under and half over.

Mathematically, specific gravity can be used to support this phenomenon.

$RD = \frac{p_{substance} }{p_{reference} }$

*In this context, water is our reference and the blocks are our substances.

Since Boyancy force can be described  $W = p_{substance}gV_{reference}$ (the weight of the fluid disperced), having a higher density p than the reference liquid inherently will cause a greater downwards force from gravity.
