If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water wouldA sink.B either sink or float.C do nothing.D float.

Respuesta :

Answer:

D float.

Explanation:

Here, neutrally buoyant in fresh water

Now,

since the specific gravity of salt water is higher than the specific gravity of the fresh water therefore, the salt water will apply more buoyant force on the object.

And as the object is neutral in fresh water, more buoyant force will make the object float in the salt water.

D) float

 If an object is neutrally buoyant in fresh water, the same object will float in salt water.

An object is neutrally buoyant when it has an equal tendency to float and sink. It doesn't go up or down.

  • When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt.
  • Because objects float better on a dense surface, they float better on salt water than fresh water. Also salt water is more denser than fresh water.
  • The denser a liquid is, the higher you will float in it.
