चाय एक अत्यंत महत्वपूर्ण पेय फसल है। इसे शुरुआत में अँगरेज़ भारत लाये थे, परन्तु आज ज़्यादातर चाय बागानों के मालिक भारतीय ही हैं। चाय का पौंधा उष्ण और उपोष्ण कटिबंधीय जलवायु, जीवांश युक्त गहरी मिट्टी तथा सुगम जल निकास वाले ढलवाँ क्षेत्रों में भलीभाँति उगाया जाता है। चाय की झाड़ियों के लिए वर्ष भर कोष्ण और पालारहित जलवायु की आवश्यकता होती है। वर्ष भर सामान रूप से होने वाली वर्षा की बोछारें इसकी कोमल पत्तियों के विकास में सहायक होती है।आज भारत विश्व का अग्रीण चाय उत्पादक और निर्यातक देश है।
Answer :- Copper (1) sulphide (CuS) .......In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu,0
‘which reacts with the remaining Cu,S (sulphide ore) to give copper metal.
CUS +2Cu0 — 6Cu +S0, 1
In this process, Cu,S behaves as reducing agent.

Mandela said that a man who takes away another man’s freedom is a prisoner of hatred because he himself is a victim of prejudice and narrowmindedness. He justified it by saying thought a man is not free if his freedom is taken away from him. Likewise, if he is taking away someone else’s freedom, he is not truly free.

i) Dipole moment of dipole is given by, i)
Force on –q at A = -qE
Force on +q at B = + qE
So,
Net force = qE – qE = 0
ii) Work done on dipole is given by,
Force on –q at A = -qE
Force on +q at B = + qE
So,
Net force = qE – qE = 0
ii) Work done on dipole is given by,
Calculation of focal length and power of correcting lens in myopia: Let x be the distance of the actual far point from the eye (distance from the concave lens placed near the eye).∴ Object distance or far point of the eye, u = – ∞Image formed, v = – x,Focal length, f =?Using lens formula, 1f = 1v-1u = 1-x-1-∞ = -1x+0 = -1x. ∴ Required focal length, f = -x Required power, P = 1f =-1x Since the power is negative, this implies that the correcting lens is a concave lens.
