The answer is 51.0 ml but can someone explain why please

Explanation:

Amount of water displaced by the sphere will be equal to the volume of complete sphere.

As the sphere completely sinks to the bottom of the cup.

We have been given;

Diameter of sphere (d) = 4.6 cm

So,

Volume of sphere (V):

By substituting value of r we get:

1 cm³ = 1 mL

V = 51 mL

So,

Water displaced by the sphere = 51 mL

the index of refraction of the second medium is higher. i just took the test trust me !

the cell cycle is the final answer! : )
