Post lab 8 Sara Irshad, Tues: 4-6 pm 1. The only limitation is the vessel size. Typically, ocean-going vessels are much larger thus requiring greater maneuvering space and greater water depth to accommodate draft. The obvious exception to this is the Great Lakes, where ocean going vessels routinely voyage. The difference of salt water vs. fresh water has no other bearing. 2.Yes because 18 g/cm3 is not the same or close enough to 19.3 g/com3 to believe its gold. 3. The least count of any measuring equipment is the smallest quantity that can be measured accurately using that instrument. Thus Least Count indicates the degree of accuracy of measurement that can be achieved by the measuring instrument. All

Unformatted text preview: measuring instruments used in physics have a least count. A meter ruler's least count is 0.1 centimeter; an electronic scale has a least count of 0.001g, although this may vary; a vernier caliper has a least count of 0.02 millimeters, although this too may vary. 4. In order for a body to float the body should be less dense than the liquid it is floating in. Even though steel is denser than water the entire structure of a steel boat has internal air enclosed, that creates the overall structure of the ship to have a less density than water making it able to float. 5. The new buoyancy force is 4.5x original buoyancy force....
