Answer : 1. "Tibet"
Explanation :
Answer: A) Tibet Explanation: Second ozone hole was detected over Tibet in the year 2006. Ozone is a form of oxygen, acts as a high-altitude atmospheric screen against cancer-causing ultraviolet light. The main source of these halogens in the stratosphere is photodissociation of man made halocarbon refrigerants, solvents, propellants and CFC's.

Answer : 3. "ATX"
Explanation :
Answer: C) ATX व्याख्या: ATX (एडवांस्ड टेक्नोलॉजी एक्सटेंडेड) एक मदरबोर्ड फॉर्म फैक्टर है जो एक 20 पिन कनेक्टर का उपयोग करता है। एटीएक्स को इंटेल द्वारा 1995 में एटी फॉर्म फैक्टर जैसे पिछले वास्तविक मानकों में सुधार करने के लिए विकसित किया गया था। यह कई वर्षों में डेस्कटॉप कंप्यूटर एनक्लोजर, मदरबोर्ड और बिजली आपूर्ति डिजाइन में पहला बड़ा बदलाव था, जिससे भागों के मानकीकरण और विनिमेयता में सुधार हुआ।

Answer : 2. "Siemens m2/equivalent"
Explanation :
Answer: B) Siemens m2/equivalent Explanation: Equivalent conductance is defined as the conductance of an electrolyte solution containing one gram equivalent of the electrolyte. It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte. λ = k x V Unit of spceific conductance k is Siemens / m. Volume of the solution V is m3 Now, required equivalent conductance unit is Siemens.m2/equivalent .
