What is the primary difference between fabrication and falsification of data in scientific research? Fabrication requires a physical model of the research findings such as a working model of an invention, while falsification merely requires a description.
Falsification must be carried out by two or more researchers, while fabrication can be effectively committed by a single, corrupt scientist
Fabrication requires creating a completely false set of data and presenting them as fact, while falsification requires the researcher to only change some results in an otherwise accurate report.
Fabrication and falsification are exactly the same unprofessional acts.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

the force on the thing and the distance the force moves the thing

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
