C. 250

D. 50

Solutions

10 sin⁴α + 15 cos⁴α = 6

⇒ 10 sin⁴α + 15 cos⁴α = 6(sin²α + cos²α)²

Dividing both sides by cos⁴α

⇒ 10 tan⁴α + 15 = 6 tan⁴α + 6 + 12 tan²α

⇒ 4tan⁴α + 9 – 12 tan²α = 0

⇒ (2tan²α – 3)² = 0

⇒ tan²α = 3/2

27 cosec⁶α + 8sec⁶α = 27 (1 + cot²α)³ + 8 (1 + tan²α)³

⇒ 27 [1 + 2/3]³ + 8 [1 + 3/2]³⇒ 125 + 125 = 250

63. Which of the following element could NOT find a fixed place in Mendeleev’s periodic table?

A. Sulphur

B. Hydrogen

C. Nitrogen

D. Oxygen

Solutions

Hydrogen is the element that could not find a fixed place in Mendeleev’s periodic table.
Mendeleev periodic law states that ‘the properties of elements are the periodic function of their atomic masses’.
Hydrogen has 1 electron in its outermost orbit hence it should be placed in s- group (Alkali metals) or group 1.
But it behaved like a halogen (group 17) which gains one electron to reach the electronic configuration of a helium atom which is a noble gas.
Hence hydrogen did not find a fixed place in Mendeleev periodic law.
