In your answer, describe the purpose of each process, the number of divisions involved, and the genetic outcome of the daughter cells. Use the scenario to explain why both processes are necessary in multicellular organisms.

What output is produced by the following Java code? class Printer {     void print() {         System.out.println(“Base class print method”);     } } class ColorPrinter extends Printer {     void print() {         System.out.println(“ColorPrinter print method”);     } } public class TestPrinter {     public static void main(String[] args) {         Printer myPrinter = new ColorPrinter();         myPrinter.print();     } }

Complete the following steps and enter the information requested in the text box at the bottom of this question.   1.  Open the following web page  Choose the option for “Friction” (you used this same simulation for an earlier assignment) 2. In the simulation window, push the Friction value up a little closer to “Lots”, but not all the way there.   Check the boxes for “Masses” and “Speed”. 3. Begin to slowly increase the force the robot applies against the side of the 50kg box shown, watching for the largest value of force it can apply before the box begins to move.  Using this information, you should be able to calculate a coefficient of friction between the box and the ground.  4. In the text box below, note the mass of the object being pushed and the largest force that can be applied before it begins to move.   Then explain in a few sentences how you can use the applied force information you found from this experiment to calculate the coefficient of friction, and indicate which coefficient of friction type it is that you will find using this method.  Use words for your explanation.  Do not mention any specific numerical values in your explanation.   To assist you with this, imagine you are writing out how you would explain the process to a visually impaired person.  You will need to use complete words to describe the steps as you will not have any visual tools that you can utilize to show what you’re talking about.  You should also avoid referring to variables with letters or abbreviations as they might be unclear or misheard.  Use the full descriptive name for each detail you talk about in your explanation.   As with ALL your physics work, begin by stating the fundamental physics equation that applies in this situation.  Then explain how you use that equation to solve for the unknown information. At the end of your explanation:  Type the resulting numerical value you calculate for the coefficient of friction from your experiment following the method you explained above in words.   5.  Return the robot to 0 Newtons applied force without changing anything else in the simulation.  Now add the wrapped present box on top of the 50kg box.  The wrapped present box has an unknown mass.  Repeat the experiment looking for the maximum applied force before the stack of boxes begins to move.  In the text box below, note the new amount for the largest force that can be applied before it begins to move.  6. In the text box below, explain in a few sentences how you can now calculate the unknown wrapped present box mass, based on the known bottom box mass and known friction coefficient of the ground surface and the maximum force that can be applied before it begins to move.   Use words for your explanation again, just as you did in your answer above. At the end of your explanation:  type the resulting numerical value you calculated for the mass of the unknown present box from your experiment following the method you explained above in words.      

STOP!!! DO NOT SCAN/UPLOAD YOUR WORK PAGES UNLESS YOU ARE DONE ANSWERING ALL EXAM QUESTIONS OR IF TIME IS RUNNING OUT FOR YOUR EXAM If you are running out of time for completing the exam, you should stop and upload the work you have completed before time runs out so that it can be counted.  Once you begin scanning/uploading your work, you are not allowed to return to any of the questions.   You should leave this step until the last 10 minutes of the exam time which have been set aside specifically for file uploading.   TO PROCEED: 1. Look at the camera and state “I am done with my exam and I am beginning the file upload process now.”   2. Hold each of your work pages up briefly to show them to the camera as proof that they are the work you did during the exam. 3. Go get your phone or tablet that you have set aside out of reach and bring it back to your exam work space. 4. ON YOUR PHONE:   Open drive.google.com on your phone (or open the Google Drive app) and log in using your @my.cuesta.edu email address.   Open a new blank Google Doc and select “Insert –> Image –> Camera”.  Use your phone’s camera to take CLEAR PHOTOS of each of your work pages, showing the ENTIRE RANGE OF WORK ON EACH PAGE, and insert each image into the Google Doc.  Make sure the images are large enough to read/see and all text and equations are clearly legible.  If not, retake the photos.  Put work images related to different problems on different pages of the doc.  If the problems are not numbered/labeled in your work page images, type the problem name/number next to it in the Google doc to identify it. Give the Google Doc an appropriate title to save it to your Google Drive so you can find it using your computer.   5. Return to your computer and click this link to open Google Drive in a new tab on your computer 6. In Google Drive on your computer, locate the Google Doc you just made using your phone.  Select File –> Download –> PDF to export your Google Doc with your work images to a PDF file on your computer. 7. In the “question” below, select this PDF from your computer and upload it to complete your exam.     You may access Google DriveLinks to an external site. or Google DocsLinks to an external site. to assist you with uploading a scan of your completed work

FOR QUESTIONS 7, 8, 9 and 10, IN ADDITION TO ENTERING THE ANSWER IN THE BOX YOU WILL ALSO SHOW YOUR COMPLETE WORK STEPS TOWARDS THAT ANSWER ON 1 OR MORE BLANK PIECES OF PAPER THAT YOU WILL SCAN AND UPLOAD AT THE END OF THE EXAM.  Put a line between questions or move to a new piece of paper for each question, and write the question number in the corner of your work for that problem.

For this question, explain with words, sketches, and equations handwritten/drawn on paper all of the appropriate steps towards solving the following problem. Three masses m1, m2, and m3 are all connected together by a massless, unstretchable rope.  Masses m1 and m3 are hanging over either end of a table with the rope pulled over a frictionless, massless pulley on each side.  Mass m2 is sitting on a flat horizontal table with friction coefficients us =  0.3 and uk = 0.2  The situation looks like the following:   ON ONE PAGE OF PAPER: 1. Determine the maximum mass for m3 for which this system will remain in static equilibrium.  You should SHOW ALL STEPS required to derive this answer STEP BY STEP, utilizing applicable physics laws and equations and appropriate direction signs that match coordinate systems you indicate for each of the masses.  Your final answer for maximum m3 should be written in terms of the variables m1, m2, and one of the friction coefficients.     ON A SECOND PAGE OF PAPER: 2. Use your birth month for mass m1 in kg and your birth day for mass m2 in kg.  Write the values for these two masses m1 and m2. 3. Assume mass m3 in your system is actually 5kg heavier than the maximum mass for static equilibrium for this system based on the masses you noted above and the equation you derived on the first page.  Write this value for mass m3. 4. Show STEP BY STEP how you determine the equation for the Tension in the rope connecting masses m1 and m2, where mass m3 is now known to be greater than the maximum possible for static equilibrium in this system.  You should do this step symbolically so that your final equation could be used for any mass values and coefficients of friction. 5. Use your mass numerical values and the appropriate friction coefficient value to calculate the Tension in the rope connecting masses m1 and m2 using the equation you developed in the step above.     NOTE:  STEP BY STEP does not mean showing each and every algebra calculation step involved in rearranging values within an equation.  It means present each new Physics logic or equation step one piece at a time as if you were teaching a brand new Physics student how you use Physics laws and reasoning to assemble the appropriate mathematical equation describing this situation. Make sure all your variables are properly labeled for clarity. You can jump over intermediate calculation steps, but you can’t jump over any steps that require applying physics laws or logic to get you to the next step in the process.   SIGN YOUR NAME AT THE BOTTOM OF  BOTH PAGES   WHEN YOU HAVE COMPLETED WRITING/DRAWING YOUR WORK PAGE, SET IT ASIDE.  YOU WILL SCAN/UPLOAD IT AT THE END OF THE EXAM.
