in air, an object weights 15N. when immersed in water, it weights 12N. when immersed in another liquid, its weights 13N. determine the density of the object, the relative density of the object and the density of the other liquid?

Answer 1

the object displaces 1/5 of its weight in water, so it is 5 times the density of water

the weight change in the other liquid is 2/3 of the change in water, so the other liquid is 2/3 the density of water

Answer 2

I asked different question
You idiot

Answer 3

I don't know
