(i) The heated air from the equatorial region becomes lighter, starts ascending and after reaching higher altitudes, moves towards the polar region, i.e., towards the North and the South Pole.

(ii) Due to low temperatures at the higher altitudes, the air cools down and becomes heavier. This heavier air descends down in both the hemispheres in the region between 25° to 35° parallels.

(iii) This leads to the formation of high pressures belts in these parallels of latitudes in both the hemispheres.

(iv) This air is dry, hence the region does not get rainfall. Consequently, most of the hot deserts on the earth are found in these regions.

Three resistors of resistances R1 , R2 and R3 are joined in parallel. Derive an expression for equivalent resistance for this parallel combination.

rausch’s law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations. The molar conductivity of a solution...

Equimolar mixture of two gases \( A_{2} \) and \( B_{2} \) is taken in a rigid vessel at temperature \( 300 K \). The gases reacts according to given equations : \[ \begin{array}{ll} A_{2}(g) \rightleftharpoons 2 A(g) & K_{P_{1}}=? \\ B_{2}(g) \rightleftharpoons & K_{P_{2}}=? \\ A_{2}(g)+B_{2}(g) & \rightleftharpoons 2 A B(g) & K_{P_{3}}=2 \end{array} \] If the initial pressure in the container was 2 atm and final pressure developed at equilibrium is \( 2.75 atm \). in which equilibrium partial pressure of gas \( A B \) was \( 0.5 atm \), calculate the ratio of \( \frac{ K _{ p _{2}}}{ K _{ p _{1}}} \). [Given : Degree of dissociation of \( B_{2} \) is greateı than \( A _{2} \) ].

this is the solution!!!!

In the Quadrilateral BELT, ∠B = 80°, ∠E = 100°, ∠L = 120° then ∠T = ………………

Correct option is (D) 60° Sum of angles in a quadrilateral is \(360^\circ.\) \(\therefore\) In quadrilateral BELT, \(\angle B+\angle E+\angle L+\angle T\) \(=360^\circ\) \(\Rightarrow\) \(80^\circ+100^\circ+120^\circ+\angle T=360^\circ\) \(\Rightarrow\) \(300^\circ+\angle T=360^\circ\) \(\Rightarrow\) \(\angle T=360^\circ-300^\circ=60^\circ\)
