Answer: Geometrical representation
Explanation:
The graphs are the geometrical representation of the relationship as the graphical representation is the type of method that shows the representation of the values.
The different types of data set are used to represent the data in graphical format and it facilities easy to understand the complex data in very easy way.
We can also use the charts for quickly identify the data patterns and compare various types of measurement and result. The graphical representation is the type of representation of data in visual display format by using various graphs and chart.
Answer:
V = 6.55*10^{-6} v
Explanation:
The number density can be determined by using below formula:

where,
B is uniform magnetic field 0.74
i is current 18 A
V is hall potential difference
l is thickness 150 MICRO METER
e is electron charge 1.6 *10^{-19} C
therefore V can be determined as


V = 6.55*10^{-6} v
Landforms result from a combination constructive and destructive forces.
Hope this helps
