Asolid box made from a material whose density is rhos floats with two thirds of its volume submerged in a liquid whose density is rhol. how do the two densities compare?

Explanation:

density of the solid box material =

density of the liquid material =

Given that

solid box floats with two thirds of its volume submerged in a liquid

let V be the volume of the box

then,

⇒

so, the ratio of densities of solid and and the liquid is 2/3

the answer to this question is 60 n

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
