Initial data: m (weight of the book) = 0.5 kg; the dimensions of the book are 20×25 cm (0.2×0.25 m).
Reference data: g (acceleration due to gravity) ≈ 10 m / s2.
The pressure that the book will exert on the table is determined by the formula: P = F / S = m * g / (a * b).
Calculation: P = 0.5 * 10 / (0.2 * 0.25) = 100 Pa.
Answer: The book puts a pressure of 100 Pa on the table.
