Do you know of a place where the wind blows south and then suddenly shifts direction towards the north ?
The place is the South Pole. Until the point the wind reaches the pole, it is going south but the moment it passes the pole, it is going north.
There is a boat with a brick of gold and a brick of iron. Both the blocks are exactly 10 inch in size. If they are dropped into the surrounding water of river.
Which one of the blocks will make the water level higher?
The iron block will make the water level higher.
In actual terms, none of the block will make the water level higher. This is because, while in the boat, they have a larger effect on the water level and they are raising it. But, when they are dropped in the water, they will actually make the water level drop. But, the iron block will make the water level drop much less than the gold block because it is lighter and will have less effect on the water from the boat but will displace the same amount of water as the gold one when dropped into the water.
Imagine that you have a box which have two cogwheels – one big with 24 teeth and one small with 8 teeth. The big one is firmly attached to the center of the box which means it does not turn or move while the small one rotates around the big one.
How many times do you think that the smaller wheel will turn compared to the box when it turns once around the big one?
Three times is the most common answer however that is incorrect.
The small cogwheel will turn around four times.
You might already have deciphered that while turning against each other, the small wheel will turn three times (3*8) as the big wheel turns once (24 teeth). Now what we require is the big wheel to stop and the small one to turn around the big one. In this process, the small one will make another full turn on the way around the big one. Thus in total, it will make four turns.
Luis Garavito killed Density x Volume.
Who is Luis Garavito ?
He was Mass Murderer.
Density multiplied by volume equals mass.
Therefore, Luis Garavito killing mass would mean Luis Garavito was a MASS murderer
If an earthquake is 1 point higher on the Richter Scale than another earthquake which is actually 10 times stronger, how much stronger would an earthquake be if it was just half a point higher on the Richter scale?
The most common answer would be 5. But that’s totally incorrect. It will be the square root of 10 times stronger i.e. 3.16 times.

When Manish was three years old he hammered a nail into his favorite tree to mark his height. Six years later at age nine, Manish returned to see how much higher the nail was. If the tree grew by five centimeters each year, how much higher would the nail be?
The nail would be at the same height since trees grow at their tops.
If you drop a 15 kg iron bar and a 5 kg bag of cotton from a height of 50 meters which will reach the ground first?
Both will reach the ground at the same time since acceleration due to gravity is a constant for all objects on earth.
