Astronomers should observe in the radio wavelengths for imaging large areas of the sky quickly and cheaply, as radio telescopes can operate continuously, day or night, regardless of weather conditions. Unlike optical telescopes, which depend on clear skies and daylight, radio waves can penetrate clouds and are not affected by light pollution. Additionally, radio observations are often less expensive in terms of equipment and operation compared to other wavelengths, making them a practical choice for large-scale sky surveys.

At its height around 500 BCE, the Persian Empire covered approximately 3.5 million square miles (about 9 million square kilometers). This vast territory included parts of modern-day Iran, Iraq, Turkey, Egypt, and several other countries across the Middle East and Central Asia. The empire was one of the largest in ancient history, showcasing a diverse range of cultures and peoples.

To convert cubic meters (m³) to square meters (m²), you need to specify the height or depth of the space. Without that information, you cannot directly convert 55 m³ to m², as m² measures area while m³ measures volume. For example, if you have a height of 1 meter, then 55 m³ would equal 55 m².

Estimating the exact number of acres of pine versus mahogany trees globally is challenging due to the vast distribution and varying growth conditions of these species. Pine trees, which are more widely distributed across temperate and subtropical regions, cover millions of acres, particularly in North America, Europe, and Asia. In contrast, mahogany trees, primarily found in tropical regions such as Central and South America, are much less abundant and occupy significantly fewer acres. While precise figures may vary, it is generally accepted that pine trees dominate in terms of acreage compared to mahogany.

The area sold to the United States for $15 million was the territory of Florida, which was acquired from Spain in 1819 through the Adams-Onís Treaty. The negotiations were led by U.S. Secretary of State John Quincy Adams, and the treaty was ratified in 1821, officially transferring Florida to the U.S.

11 square feet is a measure of area equivalent to a square that is 11 feet on each side or a rectangular space totaling 11 square feet. This unit is commonly used in real estate, home improvement, and design to describe the size of rooms, offices, or outdoor spaces. For context, 11 square feet is roughly the size of a small table or a compact closet.

To heat 625 square feet, the required BTU (British Thermal Units) can vary depending on factors such as climate, insulation, and ceiling height. A general rule of thumb is to allocate about 20 BTU per square foot for adequate heating. Therefore, you would need approximately 12,500 BTU (625 sq ft x 20 BTU) to effectively heat that area. However, it's advisable to conduct a more detailed assessment for specific conditions.

New South Wales (NSW), Australia, covers an area of approximately 800,000 square kilometers, which is equivalent to about 80 million hectares. This makes it one of the largest states in Australia in terms of land area. The state's diverse landscapes include coastal regions, mountains, and rural farmland.

Yes, square tiles were indeed made with asbestos, particularly in the mid-20th century. Asbestos was used in various flooring materials, including vinyl tiles, due to its durability and fire-resistant properties. However, the health risks associated with asbestos exposure led to its decline in use and eventual ban in many countries. Today, many older buildings may still contain asbestos tiles, requiring careful handling and removal to prevent health hazards.

The number of bricks in one square meter depends on the size of the bricks and the mortar joints used in laying them. For standard modular bricks, which typically measure about 190mm x 90mm x 57mm, you can expect approximately 50 to 60 bricks per square meter when accounting for mortar. However, this number can vary based on the specific brick dimensions and the desired layout. Always check local building guidelines for precise calculations.

Aryabhata's conclusion about the Earth being a sphere was likely influenced by his work in geometry and astronomical observations. His understanding of spherical shapes and their properties, combined with the need to explain celestial phenomena, would have led him to this conclusion. Additionally, the mathematical principles of trigonometry and the study of circular motion in astronomy would have reinforced the idea of a spherical Earth.
