Asubmerged submarine alters its buoyancy so that it initially accelerates upward at 0.325 m/s^2. what is the submarine's average density at this time? (hint: the density of sea water is 1.025x10^3 kg/m^3.)

Ingrid wrote the hypothesis below. if the temperature of a liquid increases, the density of the liquid decreases because the particles move farther apart. what are the variables in her hypothesis?

What can be found in every skeletal muscle? a. nerves, bones, cartilage, and connective tissue b. tendons, cartilage, nerves, and blood vessels c. muscle fibers, nerves, connective tissue, and blood vessels d. tendons, nerves, blood vessels, and bones
