Q2. Which of the following are correct regarding North Atlantic Oscillations:

1. It is a climatic phenomenon in the North Atlantic Ocean of fluctuations in the difference of atmospheric pressure at sea level between the Icelandic low and the Azores high.

2. A positive trend is when there is a low pressure in the north (Greenland) and high pressure in midlatitude of the North Atlantic so that a large pressure gradient exists. 

3. A negative trend is when there when both north (Greenland) and midlatitude of the North Atlantic have low pressure and the gradient flattens out.

5. It is another name for Atlantic Multidecadal Oscillation

Q5. Which of the following are correct

2. Super-heavy elements are elements beyond atomic number 104

3. Super-heavy elements are found in very minute quantity in nature

4.  island of stability is a set of as-yet undiscovered heavier isotopes of transuranium elements which are theorized to be much more stable than some of those closer in atomic number to uranium.

Q6. Which of the following is correct:

a. ordinary steel and iron are non-magnetic

b. stainless steel is magnetic

c. when nickel (Ni) is added to stainless steel the result is a magnetic form of stainless steel, called austenitic stainless steel

d. Nickel and chromium that are added to iron tend to cancel the magnetic fields and the net outcome is that stainless steel becomes a non-magnetic substance
