Only one, providing it is repeatable.
One! Replication of the experiment result confirms the result in the scientific community.

All experiments are based on hypothesis that has to be tested for truth. All scientific experiments therefore follow a logical methodology to arrive at a conclusion that must have a universal result that becomes universal accepted truth in Scientific experiments. It is necessary to follow the universal methodology by collection of the data for analysis to determine the elements or functional relationship in the experimental process. It is similar to any mathematical function that proceeds from one step to the next with the application of a universal formula that is written when solved.
Your question is incredibly ambiguous. In general, scientific technique probably refers to the scientific method, which is always used with somewhat little variation.-Find a problem or question of why something happens-Hypothesize the mechanism of why it happens the way it does.-Make predictions of what the hypothesis implies (guess the outcome of experiments)-Conduct experiments based on your hypothesis to see if they match your predictions-Analyze the results and data from your experiment.It may be necessary to repeat the process. And remember, negative results (when your predictions are wrong) are still results--they show you what not to do, and how something ISN'T, which is very important in making progress.
It is necessary for a hypothesis to have two things, the words IF and THEN. Another word can be added, BECAUSE. A successful hypothesis has to have all three.
how will you ensure safety while performing experiment
It must be testable
The principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or falseness of the hypothesis, and a conclusion that validates or modifies the hypothesis.
Science is based on the principle of falsifiability. It is necessary to develop a hypothesis based on the current understanding. You then make a prediction and design tests or experiments which will either disprove the hypothesis or add support in favour of the scientific theory.
A hypothesis will be rejected if it fails the necessary testing required for it to become a scientific theory.

They do the experiment again, double check all their calculations, then they come up with a new theory if it's necessary. That's why there's no such thing as a scientific fact, only scientific theories.
yes it is necessary for every research project to have a set of hypothesis
The most important reason is if a single scientist forms a hypothesis and it is proved by his or her experiment it is still only a hypothesis. Other scientists need to repeat the experiment in every way conceivable to either prove or disprove the hypothesis. Only after the hypothesis has stood up to such scrutiny may it become a theory recognized by the scientific community. Another reason is that some research is simply too daunting and complex for a single person to complete.
In order to be able to demonstrate that a statement is true, there has to be some test for it to pass; if it does not pass the test it can be considered false. So, a statement that is testable can also be called falsifiable. That does not mean that it is false, it just means that until you have tested it, there is a theoretical possibility that it will turn out to be false. This is considered to be a necessary part of any scientific hypothesis. If you make a hypothesis which cannot be tested, then it has no scientific use.
