Answer: (a) 99.5℅ submerged
(B) 96.9℅ submerged
Explanation:
For 995 kilograms per cubic meter, It'll be the 995Kg/m3 density given, divided by the density of fresh water, which is one times ten to the three kilograms per cubic meter, and this works out to 99.5 percent submerged.
If the same person with the same density was floating in salt water, salt water has a slightly higher density of 1027 kilograms per cubic meter, this works out to 96.9 percent submerged.
When the heat of the sun shines on the water<span> in oceans, lakes, rivers and streams, the </span>water<span> evaporates, rising up into the air as </span>water<span> vapor. As it moves higher into the sky, it cools.
