Description DISCUSSION 1: Week 2 "Newton's Laws of Motion" Each week, you will reply to two discussion forum questions. You may submit your answers together or separately - just be sure you address both questions. Here are your questions for this week: Part 1 In two dimensional motion, we treat the two motions as if they were separate, but in reality they are tied together. What are some ways they are connected and how can this come into play in real world applications and situations? Part 2 Newton’s Second law of Motion (F = ma) is one of the basis of forces and motion. How is it very similar to his First law and why is finding the acceleration of the system (the main reason we use it) so important to solving physics and real world problems?
Description 1. A solid sphere with radius R has a uniform charge density p. Find the electric field both inside and outside the sphere. (Hint: Outside the sphere, Qenc does not depend on r anymore.) 2. An infinite plane slab of thickness 2H has a uniform charge density p , wherez is defined to be at the center of the slab. In the z direction, the slab extends from z = -H to z = +H. Find the electric field both inside and outside the slab. (Hint: Outside the slab, does not depend on z anymore.) 3. Consider a volume that corresponds to a section of a sphere with radius R. The spherical section spans from and . This volume has a non-uniform charge density . Find the total charge of the given volume. Some characters are not appeared here. Please see the attached file below.
Description Go to http://phet.colorado.edu/en/simulation/sound. Run the simulation. 1.Observe the sound waves coming from the speaker. a) What do the dark and light bands represent?(Remember, sound waves are longitudinal waves.) b) Why do the waves get lighter with distance from the speaker? c) How does changing the frequency and amplitude affect the depiction of the sound waves in the simulation? d) How do you think changing the frequency and amplitude affect the sound heard by the listener? 2.Press “start” and move the ruler to the center of the speaker. a) Describe how you would find the frequency of a wave if the frequency slider did not have a number display. Test your idea with a variety of waves (record them in a data table) and describe how well your procedure gives results that match the frequency display. b) Describe how you would find the period of a wave without using the frequency information. Test your idea with a variety of waves and record your experiment in a data table.Check your method by calculating the period using the frequency (T = 1/f). Show calculations. c) Hit stop and reset, and measure the distance a wave travels in a certain amount of time.Make a data table and do at least 3 trials.Find the speed of sound using v = d/t.
Description Why does Gravity Exist? Why is any body able to attract another? Where does that energy emerge from? Is there anything like gravitational repulsion?
Description Described what you have learned from learned from the lab above for physical and chemical changes. (300 word minimum response). Virtual Lab: Physical and Chemical Changes ALL LABS REQUIRE WRITTEN OBSERVATIONS, PROCEDURES, RESULTS, AND A CONCLUSION. ANY ASSIGNMENT SUBMITTED WITHOUT THESE COMPONENTS WILL BE REJECTED OR GIVEN A FAILING GRADE. In this lab, you will view videos of matter changing and determine whether the changes you observe are physical or chemical in nature. How are physical and chemical changes distinguished? In this lab, you will view videos of matter changing and determine whether the changes you observe are physical or chemical in nature. Objectives: Identify characteristics of physical changes of matter. Identify characteristics of chemical changes of matter. Recognize examples of physical and chemical changes. Click on the link below to access your lab. Once you have completed the lab answer the question below.Record observations of physical and chemical changes of matter. http://www.glencoe.com/sites/common_assets/science... link to lab
Description Read the attached article; J.M. Casperson and M.C. Linn, “Using visualizations to teach electrostatics,” American Journal of Physics 74, 316 (2006) Respond the following questions; 1. Do you believe using the visualizations described in this paper would help your students? Why or why not? 2. Do visualizations you currently use fit into the knowledge integration framework? If so, how? If not, how would you modify or supplement them?
Description Below I have included the link to a virtual lab and a word doc with questions on it based off the lab. Please answer the questions in the word doc as you do the virtual lab. Virtual Lab <------ LINK Word Doc provided below.
Description Q1. How does displacement change with time for a falling object? How might you describe the mathematical relationship between the distance and time of a falling object? Explain the answer using your data, graphs, and kinematic equations. Q2. How does the velocity of a falling object change with time? How would you describe the mathematical relationship between velocity and time of a falling object? Explain the answer using your data, graphs, and the kinematic equations. Q3. 1.Compare the slope of the velocity-time graph to the average of all your acceleration values. Are they close? What does the slope of a velocity (or speed) vs. time graph mean? Explain the answer using your data. How does the value of g that you calculated compare to the accepted value of 9.80 m/s2? What is your percent error?
