Answer:
A roller coaster ride is a thrilling experience which involves a wealth of physics. Part of the physics of a roller coaster is the physics of work and energy. The ride often begins as a chain and motor (or other mechanical device) exerts a force on the train of cars to lift the train to the top of a very tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation.
Answer:
Constrained by the extent of existing knowledge - Developing a hypothesis and designing an experiment is based on current human knowledge. Design of experiment is limited to observation method and instrument - e.g. discovery of viruses depended on the discovery of the electron microscope. Human error - e.g. mistakes can occur in recording observations or inaccurate use of measuring instrument.
Deliberately falsifying results - i.e. scientific fraud. Bias - prior confidence in the hypothesis being true/false can affect accuracy of observation and interpretation of results.

4. The Cenozoic Era experienced a series of ice ages, and specifically during the _______ ice ages the glaciers advanced and retreated four times.
5. The Cascade Mountains were formed in the Cenozoic by the geologic process of _______ along the western edge of North American continent.
Respond to the following based on your reading.
6. Describe how life was affected on Earth during the Cretaceous Period when an asteroid struck the Yucatan Peninsula in Mexico.
Explanation:
1. 75%
2. Mammals
3. Paleogene
4. Pieitocene
5. Subduction
6. The impact from the asteroid created large amounts of dust and ash in the atmosphere, blocking sunlight and reducing temperatures on Earth’s surface. The decreased sunlight stopped plants from photosynthesis, causing a major disruption in the food chain. Many herbivores and their predators went extinct.
