Answer:
results in many diffuse wources in contrast to point sources where they are identifiable
Explanation:
Accordingly, the introductory physics laboratories have the following purposes and goals:
1. To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.
2. To familiarize students with experimental apparatus, the scientific method, and methods of data analysis so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.
3. To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic "errors." This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.
Things like littering. Some people fish with toxic equipment, or leave their nets just floating in the water which can choke some ocean animals. There's global warming, which doesn't even need to be directly near the ocean. Pollution in general heats up the planet making the ice melt, drowning polar bears and penguins.
