Kurnool Caves. Traces of ash have been found in the Kurnool caves, suggesting that people were familiar with the use of fire. Fire could have been used as a source of light, to roast meat, and to scare away animals. Bhimbetka is primarily famous for its prehistoric rock paintings.

Question 2

What is the phenomenon called when the Moon comes between the Earth and the Sun?

Accepted Answer

Solar Eclipse. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun. This event can only happen during a New Moon phase. A total solar eclipse allows the solar corona to be visible to the naked eye.

Question 3

Which of the following is an example of a 'Colloid'?

Accepted Answer

Milk. Milk is a colloid where tiny droplets of liquid fat are dispersed in water. Unlike a true solution, the particles in a colloid are large enough to scatter light, known as the Tyndall effect. Muddy water is a suspension, as the particles eventually settle down.

Question 4

Who was the first Indian ruler to use 'Rocket Artillery' in warfare against the British?

Accepted Answer

Tipu Sultan. Tipu Sultan used Mysorean rockets, which were the first iron-cased rockets, during the Anglo-Mysore Wars. These rockets were highly advanced for their time and served as a prototype for British Congreve rockets. They caused significant damage and panic among the British infantry.

Question 5

Which Article of the Indian Constitution provides for the 'Adjudication of disputes relating to waters of inter-state rivers'?
