Q:

The Gulf Stream is a poleword flowing current in the Atlantic Ocean. Which one of the following statements with regard to this is not correct?

A) It is similar to the Kuroshio current in the North Pacific Ocean.	B) It transports warm, tropical water towards polar region.
C) This current is a major factor in weather along the east coast of the USA.	D) The warm water of the Gulf Stream sustains the coral reefs of West Pacific Coast.

Answer & Explanation Answer: D) The warm water of the Gulf Stream sustains the coral reefs of West Pacific Coast.

Explanation:

All are correct except 4. The Kuroshio is a north-flowing ocean current on the west side of the North Pacific Ocean. It is similar to the Gulf Stream in the North Atlantic and is part of the North Pacific ocean gyre. Like the Gulf stream, it is a strong western boundary current. Gulf stream is not present in west Pacific coast

Q:

Which one of the following statements with regard to Jet stream, an upper level tropospheric wave, is not correct?

A) It is narrow band of high-velocity wind.	B) It follows the wave path near the tropopause at elevations of 8 km to 15 km.
C) Jet streams are typically continuous over long distances.	D) In summer, the polar front jet achieves its maximum force.

Answer & Explanation Answer: B) It follows the wave path near the tropopause at elevations of 8 km to 15 km.

Explanation:

All are correct except D, as Jet streams are phenomena of winter. It is believed that jet stream exercises an important influence on the winter weather in India.

Q:

The molecular mass of sulphuric acid is 98. If 49 g of the acid is dissolved in water to make one litre of solution, what will be the strength of the acid?

A) Two normal	B) One normal
C) 0.5 normal	D) Four normal

Answer & Explanation Answer: B) One normal

Explanation:

Normality is a way of expressing concentration of a solution and can be calculated by the formula-

Normality (N) = No. of gram equivalent of solute/ volume of solution (in litre)

Gram equivalent weight of H2 SO4 = Molecular weight/ No. of Hydrogen atom = 98/2 = 49 gm

No. of gram equivalent in 49 gm of H2 SO4 = 1

So, Normality in 1 litre of solution = 1/1 = 1 N

Q:

Which one of the following statements is not correct?

A) The cathode rays originate from cathode and proceed towards the anode in a cathode-ray discharge tube.	B) The television picture tubes are nothing but cathode ray tubes.
C) The cathode rays themselves are not visible.	D) The characteristics of cathode rays depend upon the nature of the gas present in the cathode-ray tube.

Answer & Explanation Answer: D) The characteristics of cathode rays depend upon the nature of the gas present in the cathode-ray tube.

Explanation:

Cathode ray is a beam of electrons emitted from the cathode of a vacuum tube. It is invisible. Cathode ray tubes are also found in televisions and computer monitors. Since cathode ray is a beam of electrons and all electrons are identical, charge to mass ratio is same for all the gases and does not depend on the nature of gas.
