Susan is having a debate with her brother about wave movement. she believes waves will always travel the same speed if they have the same energy, no matter what the medium it is traveling through. her brother says this is not correct, and different mediums lead to different wave speeds. who is right and why?

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.

that is true   : ) hope this you

so whats the answer
