Ice Cube Melting & Anchor Thrown: Water Level Changes Explained

Click For Summary

Homework Help Overview

The discussion revolves around two scenarios involving changes in water levels: the melting of an ice cube and the effect of throwing an anchor overboard. Participants are exploring the principles of buoyancy and displacement in these contexts.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand the reasoning behind their initial conclusions regarding water level changes in both scenarios. Some participants question the assumptions made about displacement and buoyancy.

Discussion Status

Participants are engaging in a back-and-forth regarding the principles at play, with hints and references to further reading being provided. There is a mix of opinions on the outcomes, and no consensus has been reached yet.

Contextual Notes

The original poster expresses uncertainty about the reasoning behind their conclusions, indicating a need for clarification on the principles involved. There is also a hint suggesting the importance of understanding liquid displacement in both scenarios.

1. When the ice cube melts, will the water level rise, stay the same or fall? and why?

2. What happens to the height of pond when ancor thrown overboard rise, stay same or fall? Why?

I know that for the first question it's stay the same and for the 2nd question, it's fall; but i don't know why. Can someone help me out please?
Thank you.
