Can you guess the title of my next video?

Write your guess in the comments section below.

Bananas contain a radioactive isotope of potassium called K-40.

But it doesn't lead to radiation poisoning.

Unit to measure radiation exposure is sievert.

According to research, radiation exposure
should not exceed 50,000 millisieverts annually.

Eating a banana exposes us to only 0.1 microsieverts.

So, bananas won't cause radiation poisoning unless you eat millions of them at the same time.

Even though snakes have noses, they smell odors of their prey.

Mate or surroundings with the help of their tongue and vomeronasal organ.

Each time a snake flicks its tongue in air,
it collects odor particles.

Then when the tongue is brought back, the
particles are transferred to the vomeronasal organ.

This organ detects the odors and sends signals to the brain, helping the snake smell.

Now, we know that when we see with our two separate eyes.

Our brain combines the two different perspectives.

And makes a detailed image of our surrounding.

Similarly, because the tongue of a snake is
forked.

It collects odor particles from two different locations.

Helping the snake understand in which direction the odor is coming from.

And thus, making it easier to locate the prey.

Give me minimum five years to unravel its
mystery.

To answer this question, we need to understand Archimedes' principle.

An object partly or fully immersed in a liquid experiences an upward force called buoyant force.

Which is equal to the weight of the liquid displaced by it.

A ship has a long and wide base due to which the amount.

And the weight of water displaced by it increases.

Now according to Archimedes' principle, the buoyant force is equal to the weight of displaced liquid.

Hence, as the weight of displaced water increases.

The buoyant force that is the upward force exerted by the water increases, making the ship float.

Whenever we strike an object, it vibrates.

Sometimes, these vibrations influence other objects to vibrate.

The vibrations which take place under the influence of an external periodic force are called forced vibrations.

So, whenever I see delicious food, my stomach starts to vibrate.

A guitar has a hollow box which holds quite a huge volume of air.

Now, when we strike its string, it starts
to vibrate.

These vibrations influence the air in the
hollow box, producing forced vibrations in them.

Now we know that vibrations in air produce sound.

Hence, as a huge volume of air is vibrating,
the sound produced is louder.

Gravity is the attractive force with which
two objects pull each other.

However, Albert Einstein imagined gravity
as well as space and time a little differently.

His theory of general relativity unified two
separate entities space.

And time into a single entity called spacetime.

Spacetime can be considered as the fabric
of universe.

Now, just like a heavy ball creates a curve or distorts the trampoline.

Mass of an object creates a curve in spacetime.

According to Einstein, this curve is gravity.

Just like our hands create ripples in water,
moving objects create ripples in spacetime.

These ripples are termed as gravitational
waves.

Gravitational waves were directly observed
for the first time on September 14, 2015.

By Laser Interferometer Gravitational Observatory
in the US.
