explain what carbon dating is and how it used
carbon dating is a process used to estimate the age of an object, by comparing the c-14 isotopes
How does a half-life work
its tell you how old the object is
Why does a fusion bomb require a fission bomb to trigger it?
Fission provides the neutrons needed to start the fusion reaction
what is carbon dating used for
discovering the age of an organic object
why do we use carbon dating instead of other methods to find the age of natrual things
its the most efficient and accurate
what is the limit of carbon dating c-14
the limit is 50,000
When a proton transforms into a neutron during fusion, a positron is released. Why is this significant for energy production?
The positron annihilates with an electron, releasing additional energy
explain radiation decay
the rapid decay of a radiated object deteriating cause of the atoms splinting
list the differences between alpha,beta,and gamma radioactive decay types
alpha is weak and can be stopped by paper, beta is medium and can be stopped by aluimnum and gamma is strong and can be stopped by lead and concrete
how carbon dating is used to determine the age of an object
becuz of the c-14 we absorbed in our lifes wicth can help us tell that tell us the age
what is the fundamental difference between how fission and fusion release energy?
Fission splits heavy atoms while fusion combines light atoms
what are some possible errors in carbon dating
contamination and wrong material
what does carbon dating says about the age
it tells us the age and how long its been alive, dead and it total of its existance
tell the age of a sample using the half-life of carbon-14
the half-life of carbon-14 is 50,000
chain reaction in nuclear fission. What condition is necessary for this chain reaction to continue?
Additional hydrogen must be continuously added
make a example of carbon dating and test the accuaracy
a dead tree, that has been lying there
what can carbon dating do for forensics and archaeological
it can tell how long blood or a body had been on or in the ground and help solve cases and estimate how long a fossil has been dead
what is methhods for dating objects that are older than 50,000 years
just switch the material
why is uranium-235 considered unstable compared to other elements?
It spontaneously splits into smaller atoms and releases energy
how long does it take for c-14 carbon dating to not work
50,000 years
