In terms of the sequence of the scientific method, what is the immediate purpose of doing an experiment? a. asking the question. b. formulating the hypothesis. c. gathering data. d. drawing conclusions.

The correct answer will be option-C.

Explanation:

A scientific method involves various sequential steps to answer and explain the scientific question of natural phenomenon.

The method begins with making an observation, asking questions, doing background research, proposing a hypothesis, doing experiments, collecting the data, analyzing the data and suggest conclusions based on the data.

In the given question, the step followed by the doing an experiment will be collecting data or gathering data therefore, Option-C is the correct answer.

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.
