Answer:
Freedom
Explanation:
World justice to me means that everyone would stand together. There was a time way back when that people weren't judged as soon as they walk out the door. Nowadays you have to prepare yourself for the world outside everytime you see a mirror because you are looking at what they see. But life shouldn't be based on ethnicity, brands, colors, and price. It should be free. World justice to me means no judgement, no disrespect, treating others how you want to be treated, sharing, caring, and freedom to be your own person.
Hope this helps!
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.
Every institution will set a minimum qualifying score for CLEP exams. If you reach the required score, the institution will determine the credits it will award the student. The two sample scenarios where this may happen: Find out what credits can be earned, and other factors that may affect the test, the results and credit.
The net force on the bookcase in the direction of its motion is
∑ F = 65 N - F[friction] = (41 kg) (0.12 m/s²)
so that friction has a magnitude of
F[friction] = 65 N - (41 kg) (0.12 m/s²) = 60.08 N
The net force on the bookcase perpendicular to the surface is
∑ F = F[normal] - (41 kg) g = 0
so that
F[normal] = (41 kg) g = 401.8 N
If µ is the coefficient of kinetic friction, then
F[friction] = µ F[normal]
so that
µ = F[friction] / F[normal] = (60.08 N) / (401.8 N) ≈ 0.15
