The answer is A 

In the depletion layer, electrons combine with holes producing charge density so that region is depleted of charge carriers  but it has charge density .

Conclusion: Neutral but still having non zero charge density .

Its all because of oxytocin. Oxytocin is the love hormone that activates feelings of trust and love between people when it is released in the brain. Whenever Surakshya thinks of her college the production of the oxytocin hormone rises to peak but sadly she cannot express her love in anyway.

Yes, a vector which has zero magnitude is also a vector in case of two vectors travelling in opposite directions with equal magnitudes. At this case, the resultant vector has zero magnitude but it is still a vector. We call it a null vector.

ii)Transition metals and their compounds show catalytic activities because of Variable or multiple oxidation states, ability to form complexes, they provide large surface area for adsorption.

4.कमपयुटर हारडवेयर तिन परकारमा विभाजित छ। तिनीहरू हुन :

इनपुट उपकरण ( माउस, किबोरड, सकयानर)

आउटपुट उपकरण ( मनिटर, परिनटर, सपिकर)

परशोधन उपकरण (सि.पी. यु)

सोरेज उपकरण ( सिडि, पेन.डराइभ)

5.धेरै पहिले, कमपयुटरहरू मुखय रूपमा संखयाहरू गणना गरन र शबद परशोधन गरन परयोग गरिनथयो। समय परिवरतन भएसँगै, कमपयूटरले हामीलाई हामरो दैनिक कारयहरूमा मददत गरनको लागि विकसित गरेको छ। आजकल हामी वयकतिगत रमाइलोको लागि आफनो कमपयुटरलाई खेलको लागि परयोग गरेर र इनटरनेटमा जानकारी फेला पारन परयोग गरछौं। हामरो दैनिक जीवनमा कम...
