Answer: C) data design 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: A) 264 Explanation: Given 56% of 225 + 20% of 150 = ? - 109 we know that a% of b = b% of a Now, 225% of 56 + 20% of 150 = ? - 109 200% of 56 + 25% of 56 + 20% of 150 = ? - 109 112 + 14 + 30 = ? - 109 ? = 112 + 14 + 30 + 109 ? = 264

Answer: D) 10 km Explanation: Let distance = x km.Time taken at 3 kmph : dist/speed = x/3 = 20 min late.time taken at 4 kmph : x/4 = 30 min earlierdifference between time taken : 30-(-20) = 50 mins = 50/60 hours.x/3- x/4 = 50/60x/12 = 5/6x = 10 km.

Answer: B) E Explanation:

Answer: C) ATX Explanation: ATX (Advanced Technology extended) is a motherboard form factor uses one 20 pin connector.   ATX is developed by Intel in 1995 to improve on previous de facto standards like the AT form factor.

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 .
