The Van Allen radiation belts are giant swaths of magnetically trapped highly energetic charged particles that surround Earth.

• These belts, discovered in 1958, are located in the inner region of Earth's magnetosphere and consist mainly of high-energy protons and electrons.
• They are held in place by Earth's magnetic field and play a crucial role in protecting our planet from harmful solar wind and cosmic radiation.
• However, they can also pose a hazard to satellites and astronauts traveling through them.

There are several formulas and conventions used to represent the three-dimensional structures of molecules on a two-dimensional surface. The most common and important ones include:

Solid lines:
Represent bonds that lie in the plane of the paper or screen.

Solid wedges (or bold lines):
Represent bonds that are coming out of the plane of the paper or screen, towards the viewer.

Dashed wedges (or dashed lines):
Represent bonds that are going behind the plane of the paper or screen, away from the viewer. 

Existing designs could continue to coexist with a 2.0 W/kg SAR limit averaged over 10 grams of tissue until August 31st, 2013. The statement also accurately reflects that the SAR limit was averaged over 1 gram of human tissue.

The electronic components within a digital alarm clock, such as semiconductors and integrated circuits, operate based on quantum mechanical principles like the behavior of electrons in materials and quantum tunneling.

Therefore, if we are being very broad and considering the underlying technology, one might argue that the ringing of a digital alarm clock is a morning ritual enabled by devices that function due to quantum mechanics.

It's important to clarify that the act of the alarm ringing isn't itself a quantum mechanical phenomenon on a macroscopic scale, but the technology behind it is rooted in quantum mechanics.

Conduction: Metals are good conductors because they have free electrons. Silver and copper are the two best conductors of heat and electricity. Lead is the poorest conductor of heat. Bismuth, mercury and iron are also poor conductors

Ductility: Metals can be drawn into wires.

Sonority: Metals are capable of producing a deep or ringing sound when struck.

With algorithms, we can easily understand a program.

The speed-indicating mechanism of the speedometer is actuated by a circular permanent magnet that is rotated 1,000 revolutions per mile of vehicle travel by a flexible shaft driven by gears at the rear of the transmission.

Those things which do not have their own light are called 'dark objects'.
For example- chair, table, planet, book etc.

• The word geothermal comes from the Greek words geo (earth) and therme (heat).
• Geothermal energy is a renewable energy source because heat is continuously produced inside the earth.
• People use geothermal heat for bathing, beating buildings, and generating electricity.

• Hubble's constant H is 160 km/s per million-light-years.
