Basicity of oxides decreases for elements from left to right in the periodic table. The order of increasing basicity is; Cs2O> MgO > SnO2 > P4O10 > Cl2O7.
The oxides of metals are known to be basic. This is a common property of all metals. However, the basicity of metallic oxides decreases across the period. So, from left to right, the oxides of bases become less acidic.
On the other hand, the oxides of nonmetals are acidic in nature. So as we move from left to right, the oxides of metals become more acidic. The order of decreasing basicity of oxides as listed in the question is;
Cs2O> MgO > SnO2 > P4O10 > Cl2O7.

The force of the football is 8.6 N if the mass of .43 kg and it accelerates at 20 m/s².
A force is an influence in physics that causes the motion of a mass object to change its velocity, i.e. to accelerate. It can be a push or a pull, with magnitude and direction always present, making it a vector quantity.
To find the force (F) of the football, we can use Newton's second law of motion, which states that force is equal to mass times acceleration (F = m*a).
Given:
Mass (m) = 0.43 kg
Acceleration (a) = 20 m/s²
Using the formula:
F = m * a
Substituting the values, we get:
F = 0.43 kg * 20 m/s²
F = 8.6 N
Therefore, the force of the football is 8.6 N.

Your question seems incomplete, the probable complete question is:
A football has a mass of .43 kg and it accelerates at 20 m/s². What is its force?
Answer:
10 m/s²
Explanation:
Near Earth's surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second.

33% of the population of the United States is obese. Thus the correct answer is C.
The term population refers to the number of people living in a country or particular location. Generally, the population will be calculated on living organisms living in the area. For an example, the population of the United, states is 329.5 million as of 2020.
Situation of obesity refers to excessively fat present in the body which can cause risks to life and danger to well-being. The most cause of obesity is sedentary or inactive lifestyle of an individual.
According to the evidence more than one-third people of in America is under the category of obesity which decreases the average health of an Adult in the country leads to chronic diseases and disturbs the health of the country.
Therefore, option C 33% is appropriate.

Polynesia was the last part of Oceania to be settled because D. Polynesia was the furthest area from the mainland.
The reason the Europeans took so long to get to Polynesia was simply because it was very far from the mainland of the Americas and Australia.
