Homework Help Overview

The discussion revolves around calculating the density and submerged weight of a metal object, given its mass and the volume of water it displaces. The subject area includes principles of fluid mechanics and density calculations.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relevance of Archimedes' principle and the concept of buoyant force. There are questions about the interpretation of "weight under water" and whether it refers to gravitational weight or apparent weight. Some participants express confusion about the definitions and calculations involved.

Discussion Status

The discussion is ongoing, with some participants providing guidance on principles to consider, while others express uncertainty about the concepts and calculations. Multiple interpretations of the problem are being explored, particularly regarding the definition of weight in this context.

Contextual Notes

Participants mention the need for SI units and the density of water as a reference point. There is a suggestion to consult a textbook for further clarification, indicating potential constraints on available resources.

hi where would i start if i wantied to do this could you please tell me the formulas i need or how i should aproch it

A metal object has a mass of 135 g and is submerged in water. it displace 50 cm^3 of water. Calculate the density of the metal and weight of the metal under the water.answer must be in si units

Start with Archemede's principle and the formula for the buoyant force.

And when they say "calculate the weight under water," the question is vague: "weight" could mean "the force due to gravity," which will still be the same, or "weight" could mean "apparant weight" which would be the force due to gravity minus the buoyant force.
 
and they would be?
 
i am conpletly lost
 
do you know archimede's principle? It states that the weight of the fluid displaced is the buoyant force felt by the object.

For the first part- you do know what density means, do you not?

For the second part- how much water is displaced?(The density of water is [itex]1g/cm^3[/itex]
 
the density is the heviyness of an object and as for the second part is it 125000 the answer as 135 grams times 50 ^3 am i right
 
Do you have a textbook? Are you allowed to read it?
