Answer:
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
Answer:
The model appears to show the carbon dioxide molecules entering the blood cell and the oxygen molecules existing the cell.
The correct answer is - A. A few centimeters a year.
Earth's crustal plates move very slowly, between 2 cm and 5 cm (depending on the plate) annually.
