Question

Three objects made of common biomaterials have the same volume but different shapes. The objects are submerged in fresh water and hang attached by a lightweight string, as shown in the figure

Apatite= 3.2 x 10^3 kg/m3
Amalgam= 11.6 x 10^3 kg/m3
Titanium= 4.5 x 10^3 kg/m3
1). Which of the three objects experiences the greatest buoyant force?
(a) The object made of apatite
(b) The object made of amalgam
(c) The object made of titanium
(d) All the same
2). Please explain

Answer 1

The object made of amalgam experiences the greatest buoyant force.

Step-by-step explanation:

The object that experiences the greatest buoyant force is the one made of amalgam.

The buoyant force experienced by an object submerged in a fluid is equal to the weight of the fluid displaced by the object. The force is given by the formula:

Buoyant force = density of the fluid × volume of the object × gravitational acceleration

Since the volume of the three objects is the same, the object with the highest density will experience the greatest buoyant force. In this case, amalgam has the highest density, so it will experience the greatest buoyant force.
