Which of the following gives the definition of scientific theory?
A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
An explanation of some aspect of the natural world that can be repeatedly tested, in accordance with the scientific method.
A statement that describes or predicts a phenomena as it appears in nature.
An inference formed without proof or sufficient evidence.
An experiment is performed to measure the relationship between two quantities, A and B. The picture shows how the theoretical prediction compares to the experimental data. What conclusion can be made based on this experiment?
The experimental data proves the theory is wrong.
The experimental data confirms the theory.
Either the theory is wrong, or the experimental data is wrong.
No conclusion can be made with further experimentation.
Which of the following statements correctly distinguishes between a physical quantity and a unit of measure?
A unit of measure is a standard used to make measurements.
A physical quantity is a characteristic of an object which can be measured.
Units of measure are used to make measurements of physical quantities.
Physical quantities are used to make measurements of units of measure.
