Current and Drift velocity I=nAqv. Is there enough gravity to halt the expansion and recollapse the universe or not? Although the temperature of the CMB is almost completely uniform at 2.7K, there are very tiny variations, or anisotropies, in the temperature on the order of 10^-5K. Some of these might be obvious things, but I think it’d be useful to have them nonetheless! A deuterium and a hydrogen fuse to create helium and a gamma particle. The hydrogen around the core burns more fiercely and causes the outer part of the star to expand and cool down. Privacy & Cookies: This site uses cookies. D.4 – Stellar processes The Jeans criterion Stars form when a portion of interstellar cloud collapses gravitationally. The link doesn’t seem to be working. However, plotting the curves of observed data points, the rotation curve of the galaxy stays flat out to large distances, instead of falling off as predicted in the figure above (planet-like rotation). is a student initiative to provide free material to help international students prepare for the IB exams. Within our own universe, there exist many celestial bodies each with their own unique properties; the planets being no exception. If P 1 is the lung pressure, P 0 is the atmospheric pressure, then if the difference is ‘h’ then lung pressure can calculated as follows.. P 1 = P 0 + hρg..

Does anyone have any past exam papers for IB Physics? The main process for energy production in a star is nuclear fusion of hydrogen to helium. This amounts to six hydrogen atoms per cubic meter on average overall. Hey, your notes are really helpful and finals is in a month.. I’m unsure of this, but under stellar evolution on HR diagrams second paragraph, I think the first sentence is supposed to be when star runs out of ‘hydrogen’ instead of ‘helium’… correct me if i’m wrong.. Type Ia supernovae occur in a binary system — two stars orbiting one another. One of the stars in the system must be a white dwarf star, the dense, carbon remains of a star that was about the size of our Sun. Heyy David, I’m a IB student studying in MYP 5 (10 grade). Perhaps you can give a try. An open universe would be shaped like a four-dimensional saddle (infinite and unbounded).
