[question] Question. What is the function of an earth wire ? Why is it necessary to earth metallic casings of electric appliances. [/question] [solution] solution: Earth wire acts as a safety measure. When the live wire touches the metallic casing of an electric appliance, the electric current flows from the casing of the appliance to the earth through the copper wire. An electric current flows along the path of low resistance thus, current passes through the copper wire instead of human body. T...

[question] Question. Why did some people in eighteenth century Europe think that print culture would bring enlightenment and end despotism? [solution] Solution: Some people in eighteenth-century Europe thought that print culture would bring enlightenment and end despotism. Its easy and cheap availability meant that literacy would no longer be restricted to the upper classes. While the clergy and monarchs feared the enlightenment that a vast reading public would gain, reformers like Martin Luther...

[question] Question. Give an account of the Northern Plains of India. [/question] [solution] Solution: The Himalayan upliftment out of the Tethys Sea and the subsidence of the northern flank of the Peninsular Plateau resulted in the formation of a large basin. Gradually, the rivers flowing from the mountains in the north and the peninsular plateau in the south filled up this depression with deposits of sediments. This led to the formation of the Northern Plains of India. The formation of the Nor...

Read More →Why are sound waves called mechanical waves ?
[question] Question. Why are sound waves called mechanical waves ? [/question] [solution] Solution: The waves which require a medium for their propagation are called mechanical waves. Sound waves also propagate through a medium because of the interaction of the particles present in that medium. Sound waves force the medium particles to vibrate. Hence, these waves are known as mechanical waves. [/solution]...

[question] Question. Describe how the Himalayas were formed [/question] [solution] Solution: According to the Theory of Plate Tectonics, the Earth’s crust was initially a single, giant super-continent called Pangea. Its northern part was the Angara land and the southern part was the Gondwana land. The movement of the molten material below the Earth’s crust caused the crust or the lithosphere to break up into a number of large fragments called lithospheric or tectonic plates. Another important fe...

[question] Question. Distinguish between (i) Converging and diverging tectonic plates (ii) Bhangar and Khadar (iii) Western Ghats and Eastern Ghats [/question] [solution] Solution: (i)The Earth’s crust is broken up into several lithospheric or tectonic plates. These plates are constantly moving atop the Earth’s mantle (semi-solid layer of molten rocks). Based upon their motion, tectonic plates are referred to as converging or diverging. Converging tectonic plates move towards each other and form...

[question] Question. Explain how sound is produced by your school bell. [/question] [solution] Solution: When we hit a school bell by a hard gong, it moves back and forth about its equilibrium position. Thus, the edge of the bell strikes the particles in the air. When the edge moves forward, air particles are driven forward. This forward motion of the bell produces a region where the air pressure is slightly higher than average. This region is called compression. When the edge moves backward, ai...

[question] Question. How does the sound produced by a vibrating object in a medium reach your ear ? [/question] [solution] Solution: Air is the most common material through which sound propagates. When a vibrating object like prongs of tuning fork move forward, they push the molecules of the air in front of them. This is turn compresses the air, thus creating a region of high pressure and high density called compression. This compression in the air travels forward. When the prongs of the tuning ...
