How is heat transferred through empty space

Answer:

Applied Research: It is a research conducted to find solutions for specific problems in a particular field of studies. Example, health effects on food that are genetically modified.

Basic research: It is basic research on any field to have a clear understanding of something from the existing knowledge. Example, the study on evolution of the living organisms.

Control:  To increase the reliability of the result the scientific experiments decrease the number of variables (depending factors) in the experiment.

Dependent variable: This is a variable that determines the outcome of the result of an experiment depending on the independent variables. For example,  stress influence the heart rate. Heart rate is a dependent variable.

Empirical evidence: It is the collection of scientific facts directly or indirectly. These facts support the scientific nature of the research. For example,  measuring temperature, water freezing at a particular temperature and pressure.

Hypothesis: It is an explanation or assumption of a phenomenon based on limited empirical evidence. This is the first step of the research.

Independent variable: This is a variable that the experimenter has control to change. For example, stress influence the heart rate. Stress is an independent variable.

Explanation:

Newton's second law of motion states that when a certain force is acted on an object then it is equal to the mass m of that object multiplied by the acceleration a of the object.

Mathematically, the relation is as follows.

                             F = m × a

Thus, we can conclude that when an object is acted on by an unbalanced force then the object will start to accelerate.
