Answer 1 Fusion, in general, is the joining of light atomic nuclei to form heavier ones. They don't generate heat, but actually, need the energy to occur. These are endothermic reactions, so when a star has turned most of its fuel into iron, it undergoes a dynamic change. The star has lived its life up to now in equilibrium. The gravity that would pull it all together is balanced against the outward force of the energy liberated during exothermic fusion. At some point, the star will collapse. If a star is of insufficient magnitude, the collapse will signal that the star is in its last stages of life. But in stars of sufficient magnitude, there will be much more drama.
The collapse of sufficiently massive stars at the end of their iron forming stages will cause a supernova. Gravity is reclaiming the material, but it is also heating it during the collapse. This extra energy supplies sufficient heat for the fusion reactions that create elements heavier than iron up through uranium. These heavier elements are present on the earth, and they can have only come from a supernova event. The fusion reactions that create these heavy elements have tapped the heat energy created when the star collapsed.
The fusion process is detailed in a number of places. You'll find links below to investigate further.
Nuclear fusion is when two atoms fuse together to create a different atom. This can only occur under extreme conditions such as the conditions in the sun and many stars in our universe. The most common example of nuclear fusion is when two types of (known as isotopes of) hydrogen fuse together to create helium. The isotopes of hydrogen deuterium and tritium fuse to create helium. Deuterium contains one proton and one neutron and tritium contains two neutrons and one proton. Helium contains two protons and two neutrons so it takes the two protons it needs and the two neutrons it needs and spits out one neutron which is not needed. Nuclear fusion generates a huge amount of energy because it takes more energy to hold together two atoms then it does to hold together one. So it there is a lot of unneeded energy, which has to be released. Scientists believe that there used to be the only hydrogen in the universe but in the extreme conditions of the big bang, atoms fused together to create the atoms which are found in the universe today.
Answer 2 (A brief answer)Nuclear fusion is the merging of two light nuclei into one heavier nucleus. The resulting component total mass is less than the masses of the input nuclei. This mass defect changes into energy according to the mass-energy relation of Einstein (E=Mc2 ); E is the energy, M is the mass defect, c is the light speed. The joining of nuclei
Nuclear fusion is the opposite of fission. Rather than using uranium or other rare earth metals, Nuclear fusion involves the combining of two hydrogen atoms into a single helium atom. Fusion doesn't create dangerous nuclear wastes and uses a highly abundant element (hydrogen). Comparable to the sun's energy, fusion creates much more energy that nuclear fission, but as of now, scientists cannot sustain it for more that a few seconds due to the specific conditions that must exist in the reactor
Nuclear fusion is the combination (or merging) of two light nuclei (hydrogen, deuterium, tritium, ...) into one nucleus accompanied by a loss of some mass (called mass defect) that transforms into energy according to Einstein relation E=mc2
Where c is light speed (meter/sec) , m the mass defect (kg), and E is the liberated energy (Joule)
It's a phenomenon naturally occurring in stars. Light elements, such as hydrogen fuse together creating heavier elements - helium and all other elements. All elements on earth were created through nuclear fusion several billion years ago. Mankind has managed to duplicate conditions in cores of stars and created Hydrogen bomb. It's a device consisting of a nuclear bomb and a hydrogen isotopes. When the nuclear bomb detonates it creates so much heat and pressure, that the cores of hydrogen begin to fuse and create much more energy than the nuclear bomb itself. There are attempts to use nuclear fusion peacefully in devices called tokamaks and stellarators. They use superconducting magnetic coils to confine hot plasma. Recent most promising project is the ITER. It's being built in France.
Fission is reproduction of some unicellular organisms by division of the cell into two more or less equal parts. Fusion is a nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy.
Fusion means joining items together. In nuclear physics it means two nuclei joining to form a different one. The most common reaction is for two hydrogen nuclei to form helium
fusion means the joining of two or more elements or materials into one single element or result
Also called nuclear fission. Physics. the splitting of the nucleus of an atom into nuclei of lighter atoms, accompanied by the release of energy.
binary fission is SMILE JESUS LOVES U =]]♥♥
The fusion process refers to the process where 2 atoms of hydrogen fuse together to become one atom of helium. During this reaction, certain amount of hydrogen mass is converted into energy.
I did it on apex just now
Amoeba reproduces by binary fission which is a method of cell division. First, the cell chromosomes replicate. Next, the cell becomes longer and starts to break off at the centre. The cell wall fills in as it starts to break off. After the division is complete, there are two identical cells.
binary fission
binary fission is mainly four types : 1 simply binary fission eg. ameoba bacteria 2. longitudinal binary fissioneg. euglena 3.transverse binary fission eg paramecium, planaria4. oblique binary fission
Binary fission
Prokaryottic cells divide by binary fission , it replicates its DNA then divide the cell into two by cytokineses.
Binary fussion
Binary Fussion.
they reproduce by to be specific Binary Fussion
Bacteria reproduce through binary fission, a form of asexual reproduction
Two types of asexual reproduction are Budding and Binary Fission. There are also other types of asexual reproduction such as Fragmentation, Sporulation, Regeneration, and Vegetative Propagation.
it is relatively large
Fission and fussion manly occar in a star or a sun. The reason that a star or a sun is bright is because of the heat that is given off of from fission and fussion.
