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.
*In this context, water is our reference and the blocks are our substances.
Since Boyancy force can be described 
(the weight of the fluid disperced), having a higher density p than the reference liquid inherently will cause a greater downwards force from gravity.
Answer:

Answer:
1.61 * 10 ^8
3.3 * 10^-7
Step-by-step explanation:
Multiply the numbers and then add the exponents
2.3 * 10^1 * 7 * 10^6
2.3 *7 * 10^(1+6)
16.1 * 10^7
We need to make this scientific notation by moving the decimal one place to the left and adding 1 to the exponent
1.61 * 10 ^8
Multiply the numbers and then add the exponents
1.1* 10^-5 3*10^-2
1.1 *3 * 10^(-5+-2)
3.3 * 10^-7
I don't know what this is supposed to mean, but thanks for the free points! ;)
