<h3>What is Gestalt principles?</h3>
Gestalt principles is a school of thought in psychology that involves figure-ground relationship, grouping by proximity or similarity, law of continuity, and closure are all used to help explain how we organize sensory information.
Thus, the concepts of figure-ground relationship, law of continuity, and principle of closure is Gestalt principles.

Answer:
The pressure exerted on the table due to the book is 200 N/m².
Explanation:
The pressure exerted on the table due to the book is 200 N/m².
The given parameters;
mass of the book, m = 400 g = 0.4 kg
dimension of the table, = 0.10m x 0.20 m.
gravitational field strength g = 10 N/kg.
The area of the table is calculated as follows;
A = 0.1 x 0.2 = 0.02 m²
The pressure exerted on the table due to the book is calculated as follows; where;
F is the force of the book due to its weight
Thus, the pressure exerted on the table due to the book is 200 N/m².
The angle of elevation of the ground is the angle between the ground and the line of sight
The angle of elevation of the ground is 30.46 degrees
<h3>How to calculate the angle of elevation</h3>
The angle of elevation is calculated using the following tangent ratio

Evaluate the quotient

Take the arc tan of both sides

Using a calculator, we have:
= 30.46
Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
