In the figure below, an electron is released between two infinite nonconducting sheets that are horizontal and have uniform surfacecharge densities s(+) and s(-), as indicated. The electron is subjected to the following three situations involving surfacecharge densities and sheet separations. Rank the magnitudes of theelectron's acceleration, greatest first (use only the symbols >or =, for example 2>3=1).

Situation s(+) s(-) Separation
1 +s -2s 6d
2 +3s -2s 9d
3 +6s -2s 7d

This is for the found of the oral communication class ( Speech) my topic is “American Space program”.

There is a link mentioned in the top image I’m gonna put a another image!! It’s supposed to be the second and the third image and the rest I’m just gonna copy it past here!

example. Sample Video #3 (found in the speech folder) demonstrates this option.

Option 2 – You can also record a video of a PowerPoint or Keynote presentation that is advanced on a computer screen or projection screen with vocals recorded over as you advance the slides. This option does not show your face or body as you speak. (See pages 208 - 212). Vocal variety becomes extremely important if you choose this option. Sample Video #4 (found in the speech folder) shows an example of this method. In this “Special Occasion Speech” folder, you will find technical guidance for ways to create this type of presentation. You can use whatever technology you would like for this. Some possibilities are: a screen capture software such as Adobe Spark, ScreenCastOMatic, SnagIt; Mac computers’ built-

in screen recorder and you can even use Zoom to record a screen capture (the quality is low). We also give you instructions for a really low-tech but effective recording method in this folder, if the other technologies are too much. Regardless of the method you choose, the end result needs to be a video that can be uploaded to GoReact.

Your audience for this speech is a virtual audience – your classmates and instructor, yes, but imagine a virtual audience as if you were posting this creative presentation to the web where a general audience can see it, like YouTube or TikTok. You will not be required to have an in-person audience or a synchronous audience for this speech. You are telling your story with impactful oral language and pictures/visuals. Make sure you are still in a formal location to present your speech so that you can be clearly heard and so there are no background noises or disturbances.

Outlines: Write out a complete, full sentence outline for this speech. You will need a preparation outline, a final outline, and a speaking outline, just as you did for previous speeches.

Use the speaking/delivery outline (remember, these are brief notes, not the full sentence outline) when you present, with larger type and larger margins than normal so you can easily keep your place.

Identification and Magnification: Utilize the ideas of identification and magnification within your speech by regularly connecting experiences you have in common with your audience and by emphasizing your chosen values/theme with fitting language, appropriate stylistic devices, analogies and stories/narrative.

Figurative Oral Language: You must make use of figurative oral language as highlighted in the exercises. (These assist in magnification). Use at least five total uses of figurative oral language. They must be highlighted in some way and labeled like a can of beans (simile) in order to receive credit.

Creativity and Originality: These elements are crucial to this assignment. Use your own ideas and your own wording. You may not count quotes from other individuals as your own stylistic devices. For example, if you quote one of Martin Luther King’s awesome metaphors, it doesn’t count as one of your figurative oral language efforts.

Personal Connection and Values: Your speech needs to show a personal connection to the story you tell and should highlight values represented by the person/event/idea that you are commemorating.

Practice: Remember to rehearse your speech – Use the Nifty Nine!

Sources: No sources needed – only use oral citations if they are needed because you researched something.

What is the difference between erosion and deposition? 

An electron moves along the z-axis with V_z=2.5 x 10⁷ m/s. As it passes the origin, what are the strength and direction of the magnetic field at the following (x,y,z) positions when:

1. (2 cm, 0 cm, 0 cm)

2. (0 cm, 0 cm, 1 cm)

3. (0 cm, 1 cm, 1 cm)

Express your answers using two significant figures.

A positively charged particle of mass 7.21 x 10^-8 kg is traveling due east with a speed of 85.3 m/s and enters a 0.340 T uniform magnetic field. The particle moves through one-quarter of a circle in a time of 2.30 x 10^-3 s, at which time it leaves the field heading due south. All during the motion, the particle moves perpendicular to the magnetic field. What is the magnitude of the magnetic force acting on the particle?

Four long, parallel conductors carry equal currents of l =5.00 A. Figure is an end view of the conductors.

The current direction is into the page at the point A and B and out of the page at the points C and D.

 Calculate (a) the magnitude and (b) the direction of the magnetic field at point P.

A particle of charge q = -8.7 µC has a velocity of 625 m/s that lies in the x€”y plane and makes an angle of 65° with respect to the x axis. If there is a constant magnetic field of magnitude 1.6 T in the +y direction, what are the magnitude of the magnetic force on the particle?

A magnetic field directed into the page changes with time according to , where a = 0.708 T, b = 0.03 T/s², and t is in seconds. The magnetic field pole has a circular cross section of radius R = 2 cm. What is the magnitude of the electric field at point P1 when t = 4.7 s and r = 1.31 cm?

An electron experiences an acceleration of 3.50 x 10^15 m/s^2 directed out of the page as a result of travelling through a magnetic field of 3.10 x 10^-1 T directed south. Calculate the original velocity (magnitude and direction) of the electron before it entered the magnetic field.
