(adsbygoogle = window.adsbygoogle || []).push({}); 1.)1 m3 object is floating in water. A third of the object is submerged. How much does the object weigh?

2.)Consider a floating hollow plastic box that has negligible mass. The volume of the box is 0.002 m3. If a 3.5 kg piece of copper is placed in the box, will the box sink or float? Justify your answer with calculations.

3.)Two bowling balls are hung from the ceiling such that both are the same distance from the floor. At their closest point the two balls are separated by only 2 cm. If you were to take a leaf blower operating at its maximum level and aim the nozzle of the blower between the two balls, which way would the balls move. Explain using the appropriate scientific concept.

4.)An inflated balloon occupies a volume of two (2) liters. The balloon is tied with a string and weighted down with a heavy stone. What is its volume when it reaches the bottom of a pond 5.2 meters deep? Assume the atmospheric pressure is equal to 1 atmosphere and that one atmosphere will support a column of water 10.4 meters high.

I'm doing a take home quiz and skipped these four problems. I can begin setting them up, but then I get stuck and can't follow through. The first two are hardest for me because I just can't grasp the concept of buoyancy. I understand the weight displaced = the force of buoyancy. But neither of the problems give me the weight of the water displaced. And the second two problems are the last two problems on the quiz, but we never covered in class. I need a lot of direction.

Helpp???

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
