Homework Help Overview

The discussion revolves around a buoyancy problem involving a rectangular piece of wood and its behavior when placed in the ocean. Participants are exploring how to calculate the percentage of the wood's volume that remains above the water's surface.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning the relationship between the density of the wood and the ocean water, and how this affects whether the wood floats or sinks. There are attempts to clarify the concept of volume displacement and its relevance to buoyancy.

Discussion Status

The discussion is active, with various interpretations being explored regarding the conditions for floating and sinking. Some participants are providing insights into the principles of buoyancy and displacement, while others are questioning the accuracy of the density values and their implications.

Contextual Notes

There are uncertainties regarding the density values provided and the units used, which may affect the calculations. Participants are also discussing the general principles of buoyancy without reaching a consensus on the specific outcome for the wood in this scenario.

A rectangular piece of wood ( 5.0 X 4.0 X 3.0 cm) and mass 42g is thrown into the oceon, how do i calculate the percentage of volume floating above the water?
 
Physics news on Phys.org
what determines if something floats?

ocean
 
the density is 1.428 X 10^-3 kg/m3 for the wood, so it will float right completely above the ocean surface?

is this right-??

Volume submerged = Density of wood / Density of oceon water?
 
have you ever seen something float right on the ocean surface?
 
the submerged volume = the volume of water displaced.
right?
if you put a rock in a container of water, the water level rises.

now, what does displacement have to do with floating?
 
in this case i got the density of wood more than that of that oceon so i think it will sink!
 
have you ever seen wood sink?
 
how did you get the density for wood? do you have the right units?
