Answer
1)
Science is the study of the nature and behaviour of natural things and the knowledge that we obtain about them. The best discoveries in science are very simple. ... A science is a particular branch of science such as physics, chemistry, or biology.
2)When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
3)The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis.
4)Physics allows us to understand the electromagnetic radiation we use to transmit data with fiber optics and satellites and to build computers that interpret those signals and transmit data on the Internet.
