Meghna Thapar 5 years, 1 month ago

Bhil Uprisings

Economic distress, famine and misgovernment led to the uprising against the British in I 817-18. The British succeeded in suppressing the Bhil rising partly by military action and partly by conciliatory policy adopted by Elphiston. It was Govind Guru, the social and religious leader of the Bhil community for more than three decades, who was the pivotal force in uniting Bhils to demand a separate entity in the British period. The movement led to the infamous Mangarh massacre on November 17, 1913.

Shylesh Reddy 5 years, 1 month ago

When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other.

Riya Onkar 5 years, 1 month ago

This is because when the two magnets of like poles are kept facing each other the lines of forces are in opposite directions. So the like poles repel each other. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other.

Sia ? 4 years, 7 months ago

"The School Boy" is a poem written in the pastoral tradition that focuses on the downsides of formal learning. It considers how going to school on a summer day "drives all joy away".[3] The boy in this poem is more interested in escaping his classroom than he is with anything his teacher is trying to teach. In lines 16–20, a child in school is compared to a bird in a cage.[3] Meaning something that was born to be free and in nature, is instead trapped inside and made to be obedient.
