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.
Answer:
Earth will complete more revolutions than Saturn.
Explanation:
It takes one year for the Earth to complete one revolution around the Sun. Our calendar is based on this fact, but some planets may finish one revolution around the Sun faster than us, while other planets will take more time to do it. For example, it takes Saturn 29 years to complete one revolution around the Sun, on the meantime, the Earth will have completed 29 revolutions.
Neptune is the planet that takes longer to complete one revolution around the Sun, approximately 164.79 years, while it takes only 88 days for Mercury to complete one revolution.
So that way is there is a fire they can escape????
