When the weight of an object equals the weight of the water displaced (or pushed away) by the object, the object is neutrally buoyant and easy to lift to the surface. a tanker made of 2.5 * 10^3 m^3 of steel sank to the bottom of the ocean. the density of steel is approximately 8 * 10^3 kg/m^3. the density of seawater is approximately 1 * 10^3 kg/m. because gravity is pretty much the same everywhere on earth, the weight of the tanker can be assumed to be approximately equal to its mass. in cubic meters, what total volume of seawater needs to be displaced in order to lift the tanker to the surface?

Read the excerpt from the strange case of dr jekyll and mr. hyde what do dr. jekyll's thoughts reveal about him in this excerpt? [t]he inmates of my house were locked in the most rigorous hours of slumber, and i determined, flushed as i was with hope and triumph, to venture in my new shape as far as to my bedroom. i crossed the yard, wherein the constellations looked down upon me, i could have thought, with wonder, the first creature of that sort that their unsleeping vigilance had yet disclosed to he is jealous of those who can sleep through the night. he is revered for his scientific advances. he is interested in studying the movements of the stars he is proud and enthusiastic about his initial results.
