Richard Feynman Explains Fire, science homework help

/in /by

Overview

This assignment has two parts. The first part (A) requires that you have reviewed the course notes for this week. The second part (B) requires you to watch some videos and respond to prompts about them.

Part A

You will first need to review the course notes for this week, and optionally attend or watch recordings of the lecture GoTo sessions. For part A, please post at least two well thought out questions that you have over this week’s material. Questions should be based on the course notes or lectures and be related to physical science. These questions can include things you are not sure you understand, concepts you find confusing, or questions that go beyond the scope of this course. Questions that make it apparent you have not reviewed the material, have not been thorough, or show no effort, may receive partial or no credit at your instructor’s discretion. Take advantage of your chance to learn. You do not need to answer them, but these questions are mandatory and part of the grade for this activity. I will respond to one or both of your questions in the grade comments section after submission.

Part B

Below you will find links to online videos for you to watch followed by a few prompts. Your response for Part B must be a minimum of 150 words. You can choose to either watch one video and post a response of 150 words on that single video or you may watch more than one video and distribute the 150 words across more prompts. (For example, if you chose to watch two videos, your response could be 75 words each for a total of 150 words.) Each prompt might include several questions, but you do not need to answer each one. Use these questions inside each prompt to guide and inspire your response.

Can We Touch Things?

The video discusses atoms from you or any object not being to come in contact with atoms in other objects, but our atoms are not special. Most of our atoms are part of a molecule (chemical bond) but that molecule cannot touch other atoms or molecules in our body.

Prompt #1: We are just a bunch of molecules that hang out together but don’t touch each other. Is this believable? If this is the case how do we feel when we touch something? How can an object apply a force to another object?

Nuclear Bombs

Prompt #2: Knowledge is power, and science is all about gaining knowledge. This knowledge can be used for good or evil. Based on the different forms of energy you have learned about in your week 1 and week 2 course notes, what are examples of different forms of energy generated during an atomic bomb detonation? Is the technology used to produced atomic bombs also used in a peaceful manner? If so what do you think could be the danger of it? How should we handle the residual materials?

Richard Feynman Explains Fire

This video reveals what fire is and even the true origin of trees. These are two things about which most people have misconceptions.

Prompt #3: According to this video, what kind of energy do plants use to synthesize its cells? What happens to this energy once the cells are synthesized? Is this energy stored in any shape or form? If so, how could we use it?
