Homework Help Overview

The discussion revolves around calculating the density ratio of a newly discovered giant planet compared to Earth, given its radius and mass relative to Earth.

Discussion Character

  • Mathematical reasoning, Problem interpretation

Approaches and Questions Raised

  • Participants discuss methods to find the volume of the new planet and its density, with some attempting calculations based on provided mass and radius values.

Discussion Status

There are multiple attempts to calculate the density, with participants sharing their calculations and questioning the correctness of their results. Some guidance on the approach has been suggested, but there is no explicit consensus on the accuracy of the calculations presented.

Contextual Notes

Participants are working under the constraints of using relative measurements to Earth and are unsure about the numerical results they are obtaining.

A newly discovered giant planet has an average radius 13 times that of the Earth and a mass 963 times that of the Earth. Calculate the ration of the new planet's density to the Earth's density.

Find the volume of the new planet and hence its density, then divide that by the density of the Earth (you won't even need to do that numerically).
 
ok so this is what i did, 5.942x10^24 kg X 963/(169PI) = density that right?
 
i got 1.077760735e 25
 
still getting it wrong but now i have the density of the new planet as 2.663709251E17/ density of Earth 5515E3? (right?)
