Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

Check through your calculations; you may have made a rounding error or used the wrong number of significant figures.
i always got that and i tried everything. my answer is 0.789733 what should i put in!!
0.6 m is the height of the submerged part of the barge. What is volume in terms of area and the height. Find a formula in terms of the height rthaer than volume. Then apply the density for the fresh water using same equation to find the submerged height in fresh water.
