Q15. Why is the difference between the duration of day and night hardly felt at Kanyakumari but not
so in Kashmir?​

As Kanyakumari is quite near the equator at 8°4'N the day-night difference is hardly one hour there, and therefore, the duration of day and night is hardly felt at Kanyakumari. ... Kashmir is over 30° away from the equator and so the difference in duration of day and night is more there and we feel that difference.

Answer 2

Answer:

Let a,b,c,da,b,c,d are four distinct consecutive numbers in A.P. The complete set of values of xx for which 2(a−b)+x(b−c)2+(c−a)3=2(a−d)+(b−d)2+(c−d)32(a−b)+x(b−c)2+(c−a)3=2(a−d)+(b−d)2+(c−d)3 is true is (−∞,α]∪[β,∞),(−∞,α]∪[β,∞), then |α||α| is equal to
