An elegy is a sad poem

Purpose: To express grief, sorrow, or admiration for a deceased person.

Origin: The term is derived from the Greek élegos, meaning "funeral lament".

Explanation

Step 1: Find the pattern (differences)

6 − 2 = 4

12 − 6 = 6

20 − 12 = 8

30 − 20 = 10

42 − 30 = 12

The differences increase by 2 each time:

4, 6, 8, 10, 12, 14

Step 2: Find the next term

Next number = 42 + 14 = 56

Explanation

5 × 2 = 10

10 × 2 = 20

20 × 2 = 40

40 × 2 = 80

Explanation

• Sound waves are mechanical waves and need a medium to travel.
  • They travel fastest in solids, slower in liquids, and slowest in gases.
  • Solid particles are closely packed, allowing rapid vibration transfer.

90 percent *90

= (90/100)*90

= (90*90)/100

= 8100/100

= 81

Explanation

 The sum of all interior angles in any triangle is always 180 degrees

A fundamental rule in Euclidean geometry, regardless of the triangle's shape (e.g., right, equilateral, scalene).

This property is known as the Angle Sum Property. 

Explanation

The statement "To every action there is always an equal and opposite reaction" is Newton's Third Law of Motion.

This law states that for every interaction between two objects, a pair of forces is produced—these forces are equal in magnitude and opposite in direction, acting on the interacting objects.
