Question

A boat floating in fresh water displaces $16,000N$ of water. How many newtons of saltwater would it displace if it floats in saltwater of specific gravity $1.17$?

• A. $14,500$
• B. $17,600$
• C. $16,000$
• D. $28,400$

Answer 1

$16,000$

Regardless of fresh water, salt water, or mercury, simply because weight of displaced liquid is equal to the weight of the boat, weight of slat-water displaced = 16000 N
