Physics (Periods 1 and 2):
Chapter 17
Section 2: Capacitance

To do:

1) Conceptual Challenge
2) Practice B (Problems 1 and 2 only)
3) Section 2 Review (Problems 1, 2 an 3).

I was discharged yesterday.  I will be recovering at home through Sunday.  I'll be back Monday, 4/9.  So that means I'll see you Tuesday 4/10.

I still have to share the new rubric for the presentations, but hopefully you have a better idea of where we're going based on my last post.

If you have any questions, please email me.

And yes, I will grade this also.

Be good and study hard.  I'lll see you next week.

About the project ...
Regarding the project, I will post the rubric later today.  In essence, the evaluation will be based on 300 points:
-100 points from the poster or PowerPoint itself
-100 from the written report (this includes a the names of the members, title, name of the group, table of contents - the usual stuff - plus a summary of the chapter, as well as exercises, examples or handouts you give to your classmates pertaining the material) and
- 100 from the oral presentation itsld (meaning yes, all member should participate and be prepared to answer questions about the subject matter involved (easy questions, I promise!)
Do not despair, you have time  i will work a new schedule for your presentations when I get back

Using the Interactive

The Columb's Law Interactive is shown in the iFrame below. There is a small hot spot in the top-left corner. Clicking/tapping the hot spot opens the Interactive in full-screen mode. Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode.

There is a second hot-spot in the lower-right corner of the iFrame. Dragging this hot-spot allows you to change the size of iFrame to whatever dimensions you prefer.

Using the Interactive

This Interactive will open in a separate browser window on your device. Click the Launch Tool button to open the Interactive. Close the window to return to this page.

# data[].attributes.attachment_link.description
The Coulomb/s Law Interactive allows learners to explore the force of attraction or repulsion between two charged objects. The quantity of charge on the objects can be varied by dragging a slider. And the objects can be dragged closer together or further apart. The distance between objects can be measured using a built-in measuring tool.

Read and answer the following:'
1. Who is Elon Musk?
2. What are his views on AI (artificial intelligence)?
3. Do you agree or disagree with his views?  Why?

# data[].attributes.attachment_link.readable_text
Elon Musk thinks AI is more dangerous than nuclear weapons.

Speaking at the SXSW festival in Austin, Texas, Musk said that the rate of improvement in artificial intelligence "scares the hell" out of him.

Musk warned that AI development should be regulated.

Elon Musk, the tech billionaire who wants to colonize Mars, is seriously worried about advances in artificial intelligence.

Speaking during a Q&A at the SXSW film festival and tech conference in Austin, Texas, on Sunday, Musk said the two things that stress him most in life right now are production difficulties with the Tesla Model 3 electric car and the dangers of AI.

"I'm really quite close, very close to the cutting edge in AI. It scares the hell out of me," Musk said. "It's capable of vastly more than almost anyone on Earth, and the rate of improvement is exponential."

Musk cited Google's AlphaGo, a software powered by AI that can play the ancient Chinese board game Go, as evidence of the rise of the machine. In early 2017, AlphaGo clinched a decisive win over the number-one player of Go, the world's most demanding strategy game.

Musk also predicted that advances in AI will let self-driving cars handle "all modes of driving" by the end of 2019. He said he thinks Tesla's Autopilot 2.0 will be "at least 100 to 200%" safer than human drivers within two years. Musk imagines drivers can sleep at the wheel someday.

The rate of improvement excites and worries Musk. He expressed a need for regulating AI development to ensure the safety of humanity, but he didn't say who should regulate it.

"I think the danger of AI is much bigger than the danger of nuclear warheads by a lot," Musk said. "Nobody would suggest we allow the world to just build nuclear warheads if they want, that would be insane. And mark my words: AI is far more dangerous than nukes."

Musk wants to create a Plan B society on Mars

Musk has a back-up plan in case nuclear war - or AI - wipes out the human race.

The SpaceX founder wants to put 1 million people on Mars as a sort of Plan B society. He told the crowd at SXSW that it would be ideal to get the base operational before a World War III-type event happens.

In the event of nuclear devastation, Musk said, "we want to make sure there's enough of a seed of civilization somewhere else to bring civilization back and perhaps shorten the length of the dark ages. I think that's why it's important to get a self-sustaining base, ideally on Mars, because it's more likely to survive than a moon base."

yet to detail exactly how hypothetical Mars colonists will survive for months or years on end.

Here is the Study Guide for Chapter 2. I am attaching a third page with a summary of terms and formulas. You may find this summary useful, especially for the free-fall exercises.
Please remember that for free-fall analysis, our equations are the same we saw in Section 2-2, except that we use "y" instead of "x" and our acceleration "a, " is known (-9.81 m/s^2).

In this summary, the author refers to the free-fall acceleration as - 10 m/s^2. For purposes of the exam, please disregard the author's assumption.

I will be absent on Wednesday.  However, please come to class, as I will leave your work ready for the substitute teacher.

You will work on an activity using the Projectile Simulator Interactive tool.  The assigned activity may be found here:
Projectile Motion.
You may work on the following activities for extra credit: Horizontally-Launched Projectiles
and
Angle-Launched Projectiles

Each of these activities has a PDF document with instructions and exercises.  Please print and start working on the document for the activities you chose to do.  Remember that you must complete the document for the Projectile Motion.  If you can't access or print this file, I will leave copies for you on Wednesday.

Remember to show all your work.

This is an individual assignment.

You have until Thursday, November 9, 2017 at 2:30 PM to work on this exercise. If you have questions about the assignment, experience any difficulty accessing the files or need additional help, please see me or send me an email as soon as possible.

This activity concludes our study of Chapter 3 and Projectile Motion.  We will not have a test.

# data[].attributes.body
You can access the Projectile Simulator from PhET here. This is a slightly more complex, but very useful tool. You may use it to double check your work in the assignment.

Remember: if you encounter any difficulties accessing these tools, please do not hesitate to contact me right away.

See you on Monday!
