Answer:
7.5 cm
Explanation:
In the figure we can see a sketch of the problem. We know that at the bottom of the U-shaped tube the pressure is equal in both branches. Defining 
Ethyl alcohol density and 
Glycerin density , we can write:
Simplifying:
On the other hand:
Rearranging:
Replacing (2) in (1):
Rearranging:
Data:
Explanation:
Given that,
A person walks 9.0 km directly east and then turns left and heads directly north for 12.0 km.
We need to find his displacement from the starting position.
We know that,
Displacement = shortest path covered
For direction,
Hence, this is the required solution.

<span>1. Plasma membrane - also known as cell membrane. It is 'the skin of a cell', which acts as a physically controlling barrier for the entrance and exit of materials. It's made up of proteins and lipids.
2. Cytoplasm - everything inside the cell (but not including the nucleus). Much of the cytoplasm is a transparent and gel-like material known as cytosol; cell structures are suspended in it.
3. Ribosomes - these are organelles that are in charge of making proteins.
<span>4. DNA - Molecules containing the genetic code of a cell, which tells the cell what to do. It is located in the nucleus for eukaryotic cells; for prokaryotic cells, it is located in a part of the cell called the nucleoid.</span></span>
