During fusion we actually fuse two light nuclei into heavy nuclei. For e.g. Hydrogen is fused to form helium and by which binding energy per nucleon increases which make nucleus more stable and hence the process will release large amount of energy
During fusion we actually fuis to lighter nuclie into a heavy neucleous.. for eg hydrogen is fues to form helium and by which binding energy per neucleon increses which make nucleousore stabe and hence the process will release large amount of energy
Dense core is needed for fusion in stars which is fulfilled by huge gravitational force to start fusion in stars. And at the core of a star temperature is over 100m K due to huge pressure and density (Sun consists of 99 % of solar system mass !! So you can imagine the pressure and density at core , this pressure and density "crushes" hydrogen atoms to give helium , which starts the process of fusion)
17:05 Yeh galat nhi hain mass can not be converted into energy Kyuki iska toh yeh matakb hua ki energy create hori h Par energy can not be created nor destroyed
42:30 sir aapne kha force is repulsive after 1fm or something but this is false.. Acc. to ncert after 0.8fm forces are repulsive... Sry if I misunderstood you.. I m not here to blame you sir... My just asking humbly.
Hii everyone!!! Just want to know is the chptr completed....means there are more chapters in this unit like radioactivity, nuclear rxns...are they in syllabus or not... asking for 2024 boards do reply whoever knows!! :)
