The ratio of the velocity of molecular nitrogen gas to the velocity of carbon dioxide gas at the same temperature is 0.045.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm v = \sqrt{\dfrac{3RT}{M}}[/tex]
where R is the universal gas constant and M is the molar mass.
Then the ratio of the velocity of molecular nitrogen gas to the velocity of carbon dioxide gas at the same temperature.
The molar mass of nitrogen will be
N₂ = 14 × 2 = 28
The molar mass of carbon dioxide will be
CO₂ = 12 + 16 × 2 = 44
Then we have
[tex]\rm \dfrac{v_{N_2}}{v_{CO_2}} = \dfrac{\sqrt{\frac{3RT}{28}}}{\sqrt{\frac{3RT}{44}}}\\\\\\\dfrac{v_{N_2}}{v_{CO_2}} = \sqrt{\dfrac{44}{28}}\\\\\\\dfrac{v_{N_2}}{v_{CO_2}} = 0.04477 \approx 0.045[/tex]

A circle has been dissected into 16 congruent sectors. the base of one sector is 1.56 units, and its height is 3.92 units. using the area of a triangle formula, what is the approximate area of the circle? circle a is dissected into 16 congruent sectors, one sector is highlighted 27.52 units2 48.25 units2 48.92 units2 76.44 units2
The area of the circle is 48.92 units². Thus, option C is correct.
What is the area?The area is given as the space occupied by the shape and others objects. The area of a sector is given as:
Area of sector = 1/2 * base * height
The base of a sector is 1.56 units
The height of a sector is 3.92 units
The area of one sector is found as:
Areas of 1 sector = 1/2 * 1.56 * 3.92 units²
Area of 1 sector = 3.05 units²
The circle is divided into 16 sectors, thereby the area of circle will be:
Area of circle = 16 * Area of a sector
Area of circle = 16 * 3.05 units ²
Area of circle = 48.92 units²
The area of circle is 48.92 units². Thus, option C is correct.

Explanation:
The Soviet Union, officially the Union of Soviet Socialist Republics, was a socialist and communist state that spanned much of Eurasia from 1922 to 1991. It was nominally a federal union of fifteen national republics; in practice its government and economy were highly centralized until its final years. The country was a one-party state governed by the Communist Party of the Soviet Union, with Moscow as its capital within its largest and most populous republic, the Russian SFSR. Other major urban centers were Leningrad, Kiev, Minsk, Tashkent, Alma-Ata and Novosibirsk. It was the largest country in the world, covering over 22,402,200 square kilometres, and spanning eleven time zones.
The Soviet Union invaded Afghanistan to help its communist government.

Thus, the conflict lasted more than a decade and ended with the withdrawal of Soviet forces in 1989, but the consequences for both Afghanistan and the Soviet Union were long-lasting.

The surface area of the smaller solid is found to be 214 square meters.
What is Surface area?The surface area is given as the sum of the area of all the faces of a three-dimensional object.
The same shape has equivalent ratio of the surface area to volume. It is given as:

Considering area 1 and volume 1 for the larger solid, and area 2 and volume 2 for the smaller solid, substituting the values give:
