Explanation:
In positional number system,
1. each symbol represents different value depending on the position they occupy in a number.
2. In positional number system, each system has a value that relates to the number directly next to it. The total value of a positional number is the total of the resultant value of all positions.
3. Example: 12 can be 1 x 10 + 2 x 1, 10 + 2= 12
whereas in Non-Positional number
1. In non-positional number system, each symbol represents the same value regardless of its position
2. In non-positional number system each symbol represents a number with its own place value.
3. Example: Roman number system where I for 1, II for 2 etc.

Answer:
Air drying
Explanation:
Sanitation is the set of measures that aims to preserve or modify the conditions of the environment in order to prevent diseases and promote health, improve the quality of life of the population and the productivity of the individual and facilitate economic activity. Basic sanitation is a right guaranteed by the Constitution as the set of services, infrastructure and operational installations for water supply, sanitary sewage, urban cleaning, urban drainage, solid waste and rainwater management.
Sanitation can be carried out in several ways, except for dry air, as this would damage the quality of sanitation and the environment.
Sanitation is important in treated water, sewage collection and treatment services lead to an improvement in the quality of people's lives, especially in child health, with a reduction in child mortality, improvements in education, in the expansion of tourism, in the valuation of properties, in income of the worker, in the cleaning of rivers and preservation of water resources, etc.

I can't give an exact number if the original velocity of ds-1 is not given. In that case, the final answer should just be in terms of an equation. Let's denote the original velocity to be v₀ and the days to be d.
Part a.)
v = v₀ + 9.23d
3440 = v₀ + 9.23d
9.23d = 3,440 - v₀
d = (3,440 - v₀)/9.23
Part b.)
The acceleration is the change in velocity per unit time. So, that would be 9.23 m/s per day. Since there are 86,400 s in a day:
a = 9.23 m/s / day * 1 day/ 86,400 s
a = 0.0001068 m/s²
