<h3>Plessy v. Ferguson case.</h3>
Explanation:

- However, the Supreme Court's verdict in the Plessy v. Ferguson case of 1896 was challenged by Justice Earl Warren stating that the idea of ‘separate but equal’ in public school was unconstitutional and inherently unequal.

Wind, solar and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, through total air emissions are generally much lower than those of coal and natural gas fired power plants.
The following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
<h3>How to calculate the mole ratio</h3>
The formula for calculating the mole ratio is expressed according to the formula shown:
Mole ratio is the ratio of the mass of a substance to the molar mass of the same substance.
To calculate the mole ratio
Mole = Mass(g)/molar mass(g/mol)
Hence the following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles

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.
