The displacement of the girl which the relative change in her position from her starting point. Therefore, the shortest distance between her initial and final position is 58.85 m North - West
From the sketch of the girls movement attached below, the displacement of the girl can be calculated thus :
Using Pythagoras :
Displacement, d = √(50² + 20²)
d = √(2500 + 400)
d = √2900
d = 53.851
Therefore, the displacement of the girl, which is the shortest distance between her current position and starting position is 53.85 meters NW.

Explanation:
The density of a substance tells you the mass of exactly one unit of volume of said substance.
In your case, aluminium is said to have a density of

Both of them.
An analog signal is one that is continuous in both instances of time and amplitude.
Now, in the real world examples of Analog signals are; current, voltage, temperature, pressure, light intensity etc.
Meanwhile, the digital signals are those that contain the digital values which are usually converted at specific instances from the analog signal.
This means that they can have only 2 states which is On or Off.
