Question

archimedes discovered that the upward force a fluid exerts on a submerged body is equal to
of the fluid the body displaces.
if the upward force is greater, the object
. if the upward force is less, the object
.

Explanation:

This problem is about Archimedes' principle, which is a concept in Physics (a subfield of Natural Science). Archimedes' principle states that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces. Then, based on the comparison between the buoyant (upward) force and the weight of the object: if the upward force (buoyant force) is greater than the object's weight, the object floats; if the upward force is less than the object's weight, the object sinks.

For the first blank, according to Archimedes' principle, the upward force a fluid exerts on a submerged body is equal to the weight of the fluid the body displaces.

For the second blank, when the upward (buoyant) force is greater than the object's weight, the object will float (or rise).

For the third blank, when the upward force is less than the object's weight, the object will sink.

Answer:

First blank: weight
Second blank: floats (or rises)
Third blank: sinks
