Given : Two intersecting circles, in which OO′ is the line of centres and A and B are two points of intersection. To prove : ∠OAO′ = ∠OBO′ Construction : Join AO, BO, AO′ and BO′. Proof : In ∆AOO′ and ∆BOO′, we have AO = BO [Radii of the same circle] AO′ = BO′ [Radii of the same circle] OO′ = OO′ [Common] ∴ ∆AOO′ ≅ ∆BOO′ [SSS axiom] ⇒ ∠OAO′ = ∠OBO′ [CPCT] Hence, the line of centres of two intersecting circles subtends equal angles at the two points of intersection.

Taplow tells Frank that Mr Harris is a strict disciplinarian and does not like being liked. He had even called him on the last day of school for extra work, which spoilt his mood. Despite having so many grudges against Mr Harris, taplow can't help liking him. Even he doesn't know why despite his strict nature, he likes Mr. Harris.

Dose India need to have more than one standard time? If yes, why do you think so

Posted by Srinivas Yadav 4 years, 7 months ago (10130227)

CBSE > Class 11 > Geography

1 answers

Sia ? 4 years, 7 months ago (6945213)

Yes, India needs to have more than one standard time, because there is a time gap of about 2 hours between the easternmost parts to westernmost parts to westernmost parts of the country. The large longitudinal expanse of India about 30° approximately. So even when the sun is still shining in the western coast, it is already night in the northeast. Hence, we need two or three time zones to clearly reflect diurnal changes.

Burials have been significant evidence to establish social differences within the Harappan society. The dead were generally laid in pits. There were differences in the way the burial pit was made. In some cases, the hallowed out spaces were lined with bricks. Pottery, ornaments, jewellery of both men and women have been found in some burials indicating that there could be life after death. The dead were also found buried with copper mirrors in some cases.
