1. Chemistry- the study of the structure, properties, and interactions of materials and the changes they undergo.

2. Physics- the study of matter and energy and how they interact.

3. Science- the systematic study and analysis of facts.

4. Scientific method- a process to test a proposed solution to a problem.

Explanation:

1. Chemistry is a branch of science that deals with the study of the structures, properties, and interactions of various materials with other materials. It also includes the study of such changes that may occur during such interactions.

2. Physics is also one branch of science that deals with the study of matter and energy. Contrary to chemistry, this scientific branch deals with the interaction of matter and energy, their motion, and behavior especially related to space and time.

3. Science is the systemic study and analysis of facts. It is the understanding of the natural and scientific world, dealing with the elements of how and why things work.

4. Scientific method is the method or process by which tests are made to ascertain problems and find a solution for such. It is the method of getting knowledge and solutions, the experimentation to get to a conclusive result.

thermal energy is the answer

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
