Explanation

In longitudinal waves, the particles of the medium (air molecules, in this case) vibrate back and forth in the same direction as the wave is moving.

This is how sound propagates through gases like air.

Laplace also corrected Newton's theory by including the effect of adiabatic compression, improving the accuracy of the speed of sound calculation in air.

Explanation

The Peshwa dynasty of Marathas was founded by Balaji Vishwanath,

He was the father of Baji Rao I. 

He is considered the founder because his son, Baji Rao I, inherited the position of Peshwa after his death and expanded the Maratha empire.

Explanation

Let's analyze the given sequence:

5 ? 14 10 97

Step 1: Identify a Pattern

We will check for possible arithmetic or geometric patterns.

Observing the numbers:

• 5 → ? → 14 → 10 → 97

Step 2: Check Differences

Let's check if there's an increasing or decreasing pattern:

• Difference between 14 and 10 = -4

• Difference between 10 and 97 = +87

Since the jumps are inconsistent, we may need a different approach.

Step 3: Look for an Alternating Pattern

• The missing number could fit a pattern involving alternating operations.

One possible pattern:

• $5\times 2+4=14$

• $14 - 4 = 10$

• $10 times 10 - 3 = 97$

Thus, checking backwards:

• The missing number should satisfy: $5 times 2 + 4 = ?$

• $5\times 2+4=10+4=12$

Explanation

1. Stone dropped from 400 ft tower — Impact sound heard time:

• What happens: Stone falls, hits water, sound travels back up.

• Key points:

  • Time to fall = $sqrt{frac{2h}{g}} = sqrt{frac{2 times 400}{32}} = 5 text{ seconds}$

  • Time for sound to travel up = $frac{400}{1120} approx 0.36 text{ seconds}$
    

• Total time: Around $5+0.36=5.36$ seconds (approximate).
