The normal audible frequency range for a healthy human ear typically spans from twenty Hertz to twenty thousand Hertz. Frequencies below this range are known as infrasonic, while those above are called ultrasonic.

Explanation
Ancient inscriptions and historical literature refer to the site of Ahar by names that highlight its economic importance. It is known as Tambavati, meaning "the city of copper," due to the intensive copper smelting activities discovered there. Additionally, it is referred to as Aghatpur or Aghat-durg.

Q399. Which of the following is the only major seasonal river that flows through the arid plains of the Thar Desert in Rajasthan?
Explanation
The Luni River is the only significant seasonal river that flows through the arid plains of the Thar Desert in Rajasthan. It originates in the Pushkar valley of the Aravalli Range and flows west-southwest through the desert. The river is ephemeral, carrying water only during the monsoon season, and eventually terminates in the saline marshes of the Rann of Kutch in Gujarat.
Q400. The "ecological footprint" is a concept that compares human demand on nature with the Earth’s ability to regenerate resources. It is typically measured in which of the following units?
Explanation
The ecological footprint is measured in global hectares, which represent the average productivity of all biologically productive areas on Earth. This unit allows for a standardized comparison between human demand and nature’s supply. By calculating how many global hectares are needed to support a specific lifestyle, researchers can determine whether humanity is living within the ecological limits of the planet.Answer key for these questions
