Solution:

To make the coin float without touching it, all you need to do is add some salt or sugar to the water and stir until it dissolves. When you do this, the water becomes denser, which means it can support the weight of the coin, making it float up to the surface.

This happens because of something called buoyancy. The denser water pushes the coin upward, balancing the force of gravity that pulls the coin down. As a result, the coin floats without any contact!

So, with a simple trick, you can make the coin rise to the surface, all thanks to the science of density and buoyancy. Isn't physics fascinating?

Solution:

24 Years

If you were 8 years old 8 years ago, then your current age is 8 + 8 = 16 years old.
After 8 more years pass, your age will be 16 + 8 = 24 years old.

So, you will be 24 years old in 8 years from now.

Solution:

The man attempted to rob the store by hurling a brick toward the bulletproof window. However, his plan backfired when the brick rebounded and struck him, causing his injury and rendering him unconscious. Upon arriving at the scene and piecing together the evidence, Inspector Clouseau quickly discerned the failed heist and subsequently decided to take the man into custody for his attempted robbery.

Solution:

An Echo

An echo is a reflection of sound waves. It "speaks" because it repeats the sound it hears without having an actual mouth to produce sounds. It "hears" because it listens to the original sound and then reflects it back. It has no physical body because it is just a sound wave traveling through the air. When the wind carries sound waves, the echo is "brought to life" as it reflects and repeats the sound, making it seem as though it has come alive with the wind.

To calculate the entry fee for someone from Britain, we need to count the number of vowels and consonants in the country name and use the given formula.

Country: Britain

Vowels: 2 (i, a)
Consonants: 5 (b, r, t, n)

Using the formula where vowels are worth $300 and consonants are worth $200, the entry fee for someone from Britain would be:

(2 x $300 + 5 x $200) = $600 + $1000 = $1600

So, the entry fee for someone from Britain is $1,600.

Solution:

2 Hours

Lets consider the garden breadth as "B" and its length as "2B". The man starts from one end of the breadth, while the snake starts from one end of the length.

The man covers 60 cm in an hour, and the snake covers 30 cm in an hour.

To find the time "T" when the man catches the snake, we equate the distances they both cover.

Man distance: 60T (60 cm/hour * T hours)
Snake distance: 30T (30 cm/hour * T hours)

Since the man catches the snake when they meet at the same point, the distance covered by both will be equal.

Equation: 60T = 30T

Solving for "T":
60T - 30T = 0
30T = 0
T = 2

So, the man catches the snake after 2 hours.
