By the time the light reaches us, 14 billion years later, we observe it as low-energy microwaves at a frigid 2.7K. D.4 – Stellar processes The Jeans criterion Stars form when a portion of interstellar cloud collapses gravitationally. Large telescopes have been used to count faint and distant galaxies in different direction and the numbers are always statistically the same. The CMB is a perfect example of redshift. Hey David, I take another curriculum along with the IB curriculum so at this point in the year I have already done one set of state-wide final exams for all of my subjects and frankly am exhausted of test after test! Thank you David. I believe you have the positive and negative terminals mixed up though under the battery and cells (Topic 5.3). If i may ask, how many marks were you awarded for it ? Two helium atoms fuse to create a heavy helium atom. Perhaps you can give http://web2zip.com a try. After billions of years, these little ripples in the early universe evolved, through gravitational attraction, into the planets, stars, galaxies, and clusters of galaxies that we see today. As the universe expanded, the light was stretched into longer and less energetic wavelengths. Red giants are formed when the hydrogen in the core of the star has fused into heavier helium and helium fusions occur to create beryllium. Take note that acceleration is a vector and thus has a direction. Thanks for pointing it out. I’m starring my first year soon and I’m planning to take Physics , Maths and GloPo as HLs and Visual Art , German and English L & L as SLs .. IB Physics Revision notes for IB Physics. Small red giants (1.4 solar masses – Chandrasekhar limit) cannot withstand the pull of gravity, so it shrinks, becomes extremely hot, until it finally cools into a white dwarf. This means you see no difference in the structure of the universe as you look in different directions. ​Topic 1: Measurement and uncertainties​, Topic 7: Atomic, nuclear and particle physics, Topic 12: Quantum and nuclear physics (HL), https://www.ibrepository.com/IB%20DOCUMENTS/Data%20%26%20Formula%20Booklets/Physics/Data%20Booklet%20-%20English.pdf, http://ibdocuments.com/IB%20DOCUMENTS/Data%20&%20Formula%20Booklets/Physics/Data%20Booklet%20-%20English.pdf.

Nucleosynthesis requires high speed collisions and high temperatures. From Wikibooks, open books for an open world < IB Physics. In the popular astronomy magazines, you will probably see the mass density of the universe specified by the symbol “W”, also known as the ratio of the current density to the “critical density” described in the next paragraph. Notice that the orbital speeds falls off as you go to greater radii within the galaxy. I got a 7 fortunately. Hi, David, do you have an app on apple store? Diagrams on precision and accuracy for random and systematic errors. When do you think your option A: relativity will be done ? Description. Therefore, the star contracts and heat up because of the large kinetic energy in the particles and explode as a supernova, spilling its rich elements into space to form future stars and planets. The introduction of neutral matter allowed light to pass freely without scattering. I was wondering if you could post the raw data for your Mpemba effect IA as I found it very interesting and I’d like to see how you manipulated the graphs on Excel! This looks like an amazing app, and I’m sure I’ll use it a lot in the future, one small thing: in the second table in “Measurements and Uncertainties”, pico and femta have 10^12 and 10^15 assigned to them instead of 10^-12 and 10^-15. After the hydrogen in the star’s core is exhausted, the star can burn helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. By Cowen Physics (www.cowenphysics.com) Happy revising! A critical density universe has “flat” curvature. It is to be noted that the Hubble “constant'” is not really a constant – it is different at different cosmological times. I believe all the data I used for the IA are on the PDF document. The other can be a giant star or even a smaller white dwarf. This site hosts comprehensive IB physics revision notes I’ve made for the post-2016 examinations syllabus. This would only be possible if the universe contained enough energy to overcome gravity – dark energy. … Hi Zotac, glad that you’ve found my notes helpful.
