Unlike an Iron Age collapse, a Bronze Age collapse releases energy, since copper and tin are past the iron peak on the curve of binding energy.

Radioactive Decay Modes

[A chart of labelled drawings of various radioactive decay modes, some real and some ficticious.]

[An unstable nucleus emits an alpha particle.] Alpha Decay

[A neutron-rich neucleus emits a W- boson. Underneath is a drawing of a neutron turnt into electron.] Beta Decay

[An unstable nucleus emits a gamma ray.] Gamma Decay

[A proton-rich atom absorbs an electron from an electron shell and emits an electron neutrino. Underneath is a drawing of a proton converted into a neutron.] Electron Capture

[A proton-rich nucleus emits a W+ boson. Underneath is a drawing of a neutron turnt into a positron.] Positron Emission

[A neutron-rich/proton-deficient unstable nucleus emits a neutron.] Neutron Emission

[All the subatomic particles burst from the atom simultaneously.] Baryon Panic

[The atom is imploded by a skull, cracking the surrounding area and sending neutrons and protons flying off.] Omega Decay

[Electrons around the atom fall to the ground.] Electron Wilt

[Protons and nuetrons combine to make a single huge baryon.] One Big Nucleon

[The nucleus rots with mushrooms growing out from it.] Fungal Decay

[The atom floats on water, with boats on either side full of tiny people shooting arrows at it.] Collapse Due to Invasion by the Sea Peoples

What’s primordio??

Good question (I have no idea)

...Alright I have SOME idea. It's a new Minecraft series that includes Pac, JVNQ & Guaxinim (two of his friends he's been in other series with – specifically, Fuga Imposivel and Purgatory), and some other Brazilian streamers. I really don't know much about it past that! It's got some supernatural aspects and someone said it's a medieval setting, but other than that, I unfortunately don't know. I've had his stream open for the last 2 hours and I'm still lost, but he seems to be having fun.

#i talk #replies #primordio talk #I'll be real this is the first time my inbox has actually worked in ages #I just saw all the messages in here I never got notifications about.... my bad #nuclei #They had a fanart room in one area though that made me think of the fanart museum. so that was cute

The Space, Astronomy & Science Podcast. SpaceTime Series 27 Episode 26 *The Brightest and Fastest Growing Black Hole Quasar Ever Seen Astronomers have uncovered a cosmic colossus: the most luminous quasar known, powered by a black hole 17 billion times the mass of the Sun and growing at a staggering rate. The quasar J0529-4351, situated over 12 billion light-years away, is a beacon from the early universe, challenging our understanding of black hole formation and growth. *Supernova 1987A's Hidden Heart: The Neutron Star Within NASA's Webb Space Telescope has pierced through the dusty veil of Supernova 1987A, revealing emissions indicative of a neutron star's presence. This discovery resolves a long-standing debate and provides a glimpse into the violent stellar processes that forge these dense remnants. *Surviving the Cosmic Rays: Earth's First Life and the Shield of Manganese How did life's early building blocks endure Earth's intense radiation? New research suggests that cell-like structures with manganese-based antioxidants could have been life's ancient protectors, enabling the survival and evolution of the first organisms in a gamma-ray-blasted world. *Leap Year Explained: Why February Gains an Extra Day As February 29 approaches, we demystify the leap year phenomenon. Learn how this calendrical correction ensures our timekeeping stays in harmony with Earth's orbit, and discover the historical and astronomical significance behind the extra day in February. Join us on SpaceTime as we delve into the depths of black holes, witness the aftermath of stellar explosions, and explore the primordial resilience of life on our planet.

Les chansons addictives que j'écoute toujours en boucle (partie 1)

Bon, évidemment, sans surprise puisqu'elle est la plus écoutée de mon Spotify depuis 2 ans 😉 Instru hypnotique à souhait, surtout la fin...

Celle-ci avait été la plus écoutée de mon Spotify en 2019 😊

Et oui, je plonge dans les vieux trucs😁 mais j'adore cette musique à la fois énergique et hypnotique.

Je ne sais pas pourquoi je suis autant addicte au rythme répétitif de cette guitare acoustique 🤔😁

Dommage que le groupe n'existe plus depuis quelques temps, mais je reste toujours addicte à cette chanson...

Endothermic is negative in physics, hence

Energy in nuclear reactions (Q) is always positive

As they are exothermic~

Multinucleate spores of a soil fungus. One cell typically carries one nucleus. In contrast, as seen here, an arbuscular mycorrhizal (AM) fungal cell carries hundreds of nuclei.

Hi nat thanks for the music ask! My turn, 5 and 27!

5. A song that needs to be played LOUD.

no contest, anything by Scene Queen. But also, my constant go to for scream-singing is

27. A song that breaks your heart.

bleach by SOAK. "I can't compete with anatomy, I'll never be the real deal" shatters my heart every time. (Totally did not have this song on repeat during a depressive episode)

Class 12 Physics Chapter 13 NCERT notes

Introduction to Class 12 Physics - Nuclei: In the realm of physics, the study of atomic nuclei constitutes a pivotal and intriguing segment, forming the nucleus of Class 12 Physics. Delving into the heart of matter, this section unravels the intricacies of the atomic nucleus, where protons and neutrons converge to define the essence of elements. From the formidable forces that bind these particles to the dynamic processes of radioactive decay, Class 12 Physics - Nuclei unveils the mysteries that govern the core of our physical reality.

As students embark on this journey, they will explore the minuscule dimensions of the nucleus, grapple with the potent forces that operate within, and unravel the applications that extend from nuclear power generation to medical diagnostics. The study of nuclei encapsulates the very essence of matter and energy, offering profound insights into the fundamental nature of the universe. Through an exploration of nuclear reactions, radioactivity, and the applications that span from energy production to medical advancements, Class 12 Physics - Nuclei equips students with a comprehensive understanding of the microscopic world that shapes the macroscopic reality we inhabit. The journey into the heart of the atom awaits, promising a voyage into the fundamental building blocks that define the physical universe. Nuclei - Class 12 Physics Structure of Nucleus:

Composition: Nucleus consists of protons and neutrons. Protons: Positively charged particles. Neutrons: Neutral particles.

Size: Nucleus is small compared to the size of the atom. Measured in femtometers (1 fm = 10^-15 meters.

Density: Extremely high density compared to ordinary matter. Atomic Mass Unit (amu): 1 amu = 1/12th the mass of a carbon-12 atom. Nuclear Forces: Strong nuclear force binds protons and neutrons. Short-range force acting over femtometer distances. Radioactivity:

Types of Decay: Alpha Decay: Emission of α particles (2 protons, 2 neutrons). Beta Decay: Emission of β particles (electrons or positrons). Gamma Decay: Emission of γ rays (electromagnetic radiation).

Half-life: Time for half the radioactive nuclei to decay. Varies for different substances. Nuclear Reactions: Involve changes in the atomic nucleus. Examples: Fusion, Fission. Applications:

Nuclear Power: Generates electricity through controlled fission.

Medical Use: Radioactive isotopes for diagnostics and treatments.

Radiocarbon Dating: Determines the age of artifacts using carbon-14 decay.

Nuclear Weapons: Uncontrolled nuclear reactions for destructive purposes. Understanding these concepts, equations, and examples will provide a strong foundation for the study of nuclei in Class 12 Physics. Practice solving numerical problems to reinforce your learning.

Nei mesi iniziali del 1947 vennero fondati due raggruppamenti, il Fronte Giovanile e i Nuclei Universitari

L’espressione neofascismo iniziò ad essere usata in Italia quando la seconda guerra mondiale era ancora in corso. In un’intervista pubblicata dall’edizione meridionale de «L’Unità» nel maggio 1944, Fausto Gullo, da poco nominato ministro dell’Agricoltura del secondo governo Badoglio, reputò “la ragione centrale della formazione del nuovo governo […] il massimo potenziamento del concorso italiano…
