Question

A hydraulic press has one piston with a diameter of 1 inch. If a 4-lb force is applied to the smaller piston, the force exerted on the larger piston will be: 2.3 lb 5 1b 12 lb 36 lb 81 lb Two identical blocks of ice float in water as shown. Then:  the 2 blocks displace equal volumes of water since they have the same weight block A displaces a greater volume of water since the pressure acts on a smaller bottom block A displaces a greater volume of water since its submerged end is lower in the water block B displaces a greater volume of water since the pressure is less on its bottom block B displaces a greater volume of water since its submerged end has a greater area

Explanation / Answer

4. Force exerted on larger piston will be more then smaller
   use F1/A1 = F2/A1 where F= force A = area of piston

5. a) the 2 blocks displace equal volume of water since they have same weight

   volume of water displace balances weight of object so both volume of water displaced are equal
