Question

Which of the following is observation can be categorised as an experimental science?

• A. A chemist observing the rate of a chemical reaction at different temperatures.
• B. A geologist examining the distribution of fossils.
• C. A physicist recording the results of angular momentum of a particular particle in a circular path.
• D. Both A and C

Answer 1

The correct option is D Both A and C

The observations which are obtained after performing any experiment are a part of experimental science. When the chemist is observing the effect of the chemical reaction by changing the variable which is temperature, this an experiment and the changes in the experimental object are the observations. The physicist is measuring the angular momentum which is obtained when the particle is moving in a circular path. This is an experiment and the angular momentum value is recorded.

Thus, the correct answer is option D.
