⚡️What is a scientific description of lightning and thunder?⚡️

Much about how and why lightnings form remains unknown and is the subject of scientific research.

But in general it can be described as a giant spark of static electricity that occurs in thunderstorms when electrical charge is released within the storm clouds.

The majority of lightnings occur between clouds, they are then called cloud-to-cloud lightnings.

But the charge release can also take place between thunderstorm clouds and the ground, leading to the classic cloud-to-ground lightning.

Research suggests that every second as much as 40 lightings occur in the Earth’s atmosphere.

Thunder is the acoustic shock wave that results from the heat that a lightning strike produces.

Important Laws of Physics

1.Archimedes Principle:
The principle was discovered in 3rd century B.C. by the Greek mathematician. Archimedes. It states that when a body is partially or totally immersed in a fluid, it experiences an upward thrust equal to the weight of the fluid displaced by it that i.e. its apparent loss of weight is equal to the weight of liquid displaced.

2. Avagadro’s Law:
In 1811 it was discovered by an Italian Scientist Anedeos Avagadro. This law states that equal volume of all gases under the same conditions of temperature and pressure contain equal number of molecules.

3. Ohm's Law:
It states that the current passing through a conductor between two points is directly proportional to the potential difference across the two points provided the physical state and temperature etc. of the conductor does not change.

4. Newton’s Laws.
Law of Gravitation:
Objects attract each other with a force directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between them. Hence, for objects on or near the earth, the mass of the earth is very much greater than the object, and so the gravitational force between them makes objects fall towards the earth. That is why lead and feather fall at the same rate in a vacuum.
Newton’s First law of Motion
A body continues in its state of rest, or of uniform motion in a straight line, except in so far as it is compelled by external impressed forces to change that state. It is also called Law of Inertia.
Newton’s Second Law of Motion
The rate of change of momentum is proportional to the impressed force and takes place in the direction of the straight line in which the force acts. In other words “Force is equal to mass multiplied by acceleration”.
Newton’s Third Law of Motion
To every action there is equal and opposite reaction. This is the principle behind the recoil felt on pulling the trigger of a gun.
Newton’s Law of cooling
The rate at which a body cools or loses its heat to its surroundings is proportional to the excess of mean temperature of the body over that of the surroundings, provided this temperature excess is not too large.

5. Coulomb’s Law:
The force between the two electric charges reduces to a quarter of its former value when the distance between them is doubled. The SI unit of electric charge, coulomb, is named after Charles Augustin de Coulomb who established the law.

6. Stefan’s Law:
The total energy radiated from a black body is equal to the fourth power of its absolute temperature.

7. Pascal’s Law:
- When pressure is applied to a fluid, the pressure change is transmitted to every part of the fluid without loss. Hydraulic machines like the hydraulic press work on this principle.
- Atmospheric pressure decreases with increase in height. The SI unit of pressure is pascal which is named after Pascal who established this law.

8. Hooke’s Law:
This law states that the extension of a spring is proportional to the tension stretching it. Doubling of the tension results in the doubling of the amount of stretch

9. Bernoulli's Principle:
It states that as the speed of a moving fluid, liquid or gas, increases, the pressure within the fluid decreases. The aerodynamic lift on the wing of an aeroplane is also explained in part by this principle.

10. Boyles's Law:
It states that temperature remaining constant, volume of a given mass of a gas varies inversely with the pressure of the gas.

11. Charles's Law:
It states that pressure remaining constant, the volume of a given mass of gas increases or decreases by 1/273 part of its volume at 0 degree Celsius for each degree Celsius rise or fall of its temperature.

12. Kepler's Law:
Each planet revolves round the Sun in an elliptical orbit with the Sun at one focus. The straight line joining the Sun and the planet sweeps out equal areas in equal intervals. The squares of the orbital periods of planets are proportional to the cubes of their mean distance from the Sun.

Why are American sequoias so large and tall?

Two species of American redwoods, scientifically known as sequoia and sequoiadendron, belong to sequoioideae, a subfamily of coniferous trees within the family cupressaceae, and are the tallest and largest trees on the planet.🌲

📍The tallest sequoia measures at 115 meters (380 feet) high and the largest one has a diameter of 11 meters (36,5 feet) with an estimated mass of over 1,910 tonnes.

Sequoias grow so tall and large because they live a very long time and grow relatively quickly.

To thrive they require a great amount of water, which they primarily receive from the snow that accumulates in the mountains in winter and soaks into the ground when melting in spring.

Sequoias need well-drained soil, so walking around the base of the tree can cause it harm, as it compacts the soil around their shallow roots and prevents the trees from getting enough water.

What toy is considered the most harmful?

The answer to this question is lawn darts, also known under a military styled name Javelin darts, a lawn game for two players or teams that appeared in stores in the 1960s.

Its set usually includes four large darts and two targets in the form of a plastic ring.

30cm (12 inches) in length with a weighted metal or plastic tip on one end and three plastic fins on a rod at the other end, the darts are intended to be tossed underhand toward a horizontal ground target.🤯

❗️After more than 6,000 recorded injuries and at least 3 children's deaths 😢, attributed to this game, it was banned in the US 🇺🇸 and Canada 🇨🇦 in 1988.

Nevertheless, lawn darts remain legal in Europe.🇪🇺

How big can a lightning actually get?

While most lightning flashes measure at 3.2 to 4.8 kilometers (2 to 3 miles) in length, some truly colossal bolts occasionally crackle above our heads.

Vertically, the extent of a flash is limited by the height of a storm cloud, or the distance from the ground to its pinnacle, which is about 20 km (12 miles) at its highest.

But horizontally, an extensive cloud system provides much more room for the heavyweights of lightning division.

In April 2020 American meteorologists recorded a megaflash that stretched from Texas to Mississippi, covering 768 km (477 miles).

According to scientists, the larger the parent cloud, the more opportunity there is for the discharge to continue propagating, hence there are likely much bigger flashes out there.

At the same time, megaflashes aren't more dangerous than regular lightning and don’t necessarily carry more energy.

Some facts about Gravitational waves:-
Gravitational waves are ‘ripples’ in the fabric of space-time caused by some of the most violent and energetic processes in the Universe.

When an object accelerates, it creates ripples in space-time, just like a boat causes ripples in a pond.
These space-time ripples are gravitational waves. They are extremely weak so are very difficult to detect.

Two objects orbiting each other in a planar orbit such as a planet orbiting the Sun or a binary star system or the merging of two black holes will radiate Gravitational waves.

Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.

Einstein’s mathematics showed that massive accelerating objects (such as neutron stars or black holes orbiting each other) would disrupt space-time in such a way that ‘waves’ of distorted space would radiate from the source.

Furthermore, these ripples would travel at the speed of light through the Universe.

Hydroelectric Energy ✅

Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity.

How Does Hydroelectric Energy Work?

Most hydroelectric power plants have a reservoir of water, a gate or valve to control how much water flows out of the reservoir, and an outlet or place where the water ends up after flowing downward. Water gains potential energy just before it spills over the top of a dam or flows down a hill. The potential energy is converted into kinetic energy as water flows downhill. The water can be used to turn the blades of a turbine to generate electricity, which is distributed to the power plant’s customers.
