Charges and Fields PhET LabToday, you will use the Charges and Fields PhET lab to map the electric field around one or more point charges.https://phet.colorado.edu/en/simulation/charges-and-fields Beginning Observations1) Open the Charges and Fields PhET simulation. What can you change about the simulation?2) What do the “E-field sensors” show? 3) Select, show E-field. How does the color of the arrow relate to the strength of the field? 4) How can you make a charge of +2q? -3q? Part 1 – Field around isolated point charges5) Draw the field lines for the scenarios below. Make sure you are sketching continuous field lines. 4q-2qPart 2 – Field around two point charges in a line6) Draw the field lines for the scenarios below. Make sure you are sketching continuous field lines. Two unequal, unlike point chargesTwo equal point chargesPlace a test e-field sensor anywhere on the screen for both scenarios and draw what you see. 7) When you have two like charges in a line – where is the electric field the greatest? Is there ever a point where the field will be zero? 8) When you have two unlike charges in a line – where is the electric field the greatest? Is there ever a point where the field will be zero? Part 3 – More complicated scenarios9) For this part of the lab, create three arrangements of your choice and draw the field lines you see. 3 point charges, equal, like charges4 point charges, 2 positive, 2 negative, all unequal 5 point charges all unequal, 3 positive, 2 negativePlace at least three field sensors in each of your scenarios above and draw what you see on your diagrams. Part 4 – The field around charge distributions10) Make a long line of positive charges by placing them very close together. How does the field change as you move down the line of charges? 11) Construct a parallel-plate capacitor where a second line of charges equal in size and opposite in charge are placed below the line of positive charges. Examine what the “E-field” is like between the plates using a sensor.

1) Concept maps are a way to help you organize your knowledge of a subject. Concept maps begin with a main idea (or concept) and then branch out to show how that main idea can be broken down into specific topics.You can organize concept maps in many different ways, as a quick Google image search will show you. Here’sLinks to an external site. an example of a concept map about Earth's geology. Here's a concept map about concept maps (Links to an external site.). Look them over and then create your own concept map about the moons of jovian planets, using your assigned reading. You can draw the concept map on paper and convert it to a .pdf using Genius Scan or other software. There are also digital concept map making websites like Lucidchart. You created a concept map for Homework Assignment 8. A special kind of concept map is called a flowchart, which lists the steps in a process with lines or arrows connecting them. There are two flowcharts to make for this assignment. Part 1: Venus's Changing Atmosphere (40) (and yes, Venus's is not a typo (Links to an external site.))Put the following events in order. Then create a flowchart that lists how they are connected. Each step of this flowchart should include one of the following items, except for the last step, which includes two. You may need to review your notes from the lectures 4 and 5. The first four steps in the process include one item each. The last step includes two items. Water evaporates from the rivers, lakes, and oceans on the surface of Venus. Venus gets so hot that both the day and night side are hotter than an oven set to “broil”. The presence of more greenhouse gases in the atmosphere increases Venus’ greenhouse effect. Venus is 30% closer to the Sun than Earth. Although this may not seem like much, it is enough to give the planet a higher temperature. The loss of water inhibits the CO2 cycle from taking carbon dioxide out of the atmosphere. The atmosphere thickens until it the atmospheric pressure would crush any human to set foot on the planet.Part 1: Mars's Changing Atmosphere (60)The flowchart for Mars is more complicated. It starts with one fact that immediately contributes to three separate outcomes in the next step and goes on from there. Plate tectonics slows down and eventually stops. Since Mars has only 1/3 Earth’s mass, Mars radiates away its internal heat to space within about 1-2 billion years and it’s core thickens and or solidifies.The solar wind breaks apart water molecules in Mars’s atmosphere. The hydrogen escapes to space and the oxygen reacts with surface rocks, causing Mars to take on a red color. The interruption of the CO2 cycle causes carbon dioxide to build up in Mars’s atmosphere. Volcanism slows down and eventually stops. Mars’s magnetic field weakens and eventually disappears.Lowered atmospheric pressure causes water to evaporate at lower temperatures. Mars’s slowly dries out.
