Answer:
Explanation:
We know the total diameter of the cell (assumed spherical) is:
Then its total radius
On the other hand, we know the thickness of the cell wall is and its density is the same as water (
).
Since density is the relation between the mass and the volume
:
The mass is: (1)
Now if we are talking about this cell as a thin spherical shell, its volume will be:
(2)
Where
Then:
(3)
(4)
Substituting (4) in (1):
(5)
(6)
Knowing and
:
We will determine the magnitude of the final component as follows:
So, the magnitude is approximately 8.36.
And the direction will be approximately 57.8° counter-clockwise.
This can be seeing as follows:
