Mass = 124 g
volume = 17 cm³
density = mass / volume
Therefore:
D = 124 / 17
D = 7.294 g/cm³
The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets and meteoroids. It extends from the sun, called Sol by the ancient Romans, and goes past the four inner planets, through the Asteroid Belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the teardrop-shaped heliopause. Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun. Beyond the heliopause lies the giant, spherical Oort Cloud, which is thought to surround the solar system.
The correct answer is D :)
Here we have to choose the way which is not the common way to judge the quality of the air in a particular area.
The measuring the amount of precipitation in the area is not the common way to determine air quality in an area.
The acidity of the rain causes due to the excess amount of CO₂ and SO₂ in an area. Both the gases cause pollution.
The measuring of the amount of a particular gas element is a renowned way to determine the pollution level of an area.
The ozone is a harmful gas so the measuring of its amount in ground level can identify the level of pollution in the particular area.
