i am so confused on this In the simulation, a vector is described by four measurements: |R|, Ө, Rx, and Ry. Put a vector in the work area, and then investigate to make sense of what these four things represent. In your investigation, use a wide variety of vector measurements and all three styles of Component Displays. Then, describe in your own words what the measurements represent and what “component” means.Suppose you are driving 14 miles/hour with a compass reading of 35°north of east. Represent the vector using the simulation. How fast is your car traveling in the north direction? How fast in the east direction? Figure out how the components could be calculated using geometry if you couldn’t use the simulation. Check your ideas by testing with other vectors and then write a plan for finding the components of any vector. To get to the sandwich shop, you left home and drove 6 miles south and then 10 miles west. If a bird flew from your house to the sandwich shop in a straight line, how far do you think the bird would fly? Use the simulation to check your reasoning.What direction should it fly from your house to get to the shop? Explain how you could use the simulation to answer these questions. Explain how you could use geometry equations to answer these questions.Suppose you and a friend are test driving a new car. You drive out of the car dealership and go 10 miles east, and then 8 miles south. Then, your friend drives 8 miles west, and 6 miles north. If you had the dealer’s homing pigeon in the car, how far do you think it would have to fly to get back to the dealership? Use the simulation to test ideas.The distance that the bird has to fly represents the sum of the 4 displacement vectors. Use the simulation to test ideas you have about vector addition. After your tests, describe how you can use the simulation to add vectors. A paper airplane is given a push so that it could fly 7m/s 35° North of East, but there is wind that also pushes it 8 m/s 15° North of East. Use the simulation to solve the problem. How fast could it go and in what direction would it travel? Think about your math tools and design a way to add vectors without the simulation. Check your design by adding several vectors mathematically and then checking your answers using the simulation.

John, an overweight 49-year-old man with history of diabetes and hypertension is playing soccer. After half an hour of an intense game, he feels severe chest pain that travels to his lower jaw. He is pale, diaphoretic, and short in breath. Upon arrival to the ER, an ECG was taken and the results show the following (note the changes in leads II, III and aVF): -What could be the possible reason for John’s chest pain? Explain your answer based on the clinical information. -2. How do you know John’s chest pain is heart related? How do you rule out other etiologies of chest pain such as musculoskeletal, pneumonia, and gastric sources? – How do you differentiate between myocardial ischemia and myocardial infarction?

A 42-year-old man comes to clinic with chief complaint of pain, redness, and swelling of his right calf. He states that he had been working in his yard using a string trimmer when the trimmer slipped and cut his leg. He cleaned the wound with water from the garden hose and covered the wound with a large Band-Aid. Several days later, he developed fever to 100.6˚ F and chills and noticed that his leg was swollen and red. He comes to the emergency department for definitive care. -Explain why you think the patient presented the symptoms described. -Identify the genes that may be associated with the development of the disease. -Explain the process of immunosuppression and the effect it has on body systems.

Physics Assignment Writing ServiceA good boy wants to play fetch. You throw a ball and just before it hits the ground it is moving with a velocity of 32 m/s at an angle 43° below horizontalBreak the velocity vector into components in the horizontal direction and the vertical direction. Give the magnitude and direction of each component.If you assume there is no air resistance and the ball was thrown horizontally, describe the velocity of the ball as it moves toward the ground in the horizontal and vertical directions. How are the individual components changing in magnitude? Are they accelerating, constant speed, stationary? Are they speeding up or slowing down?

Step1: Download the video clip “Ball toss up” posted on eCampus along with this lab handout and save it on your computer.Step 2: Download and install the latest version of the Tracker program from:http://www.compadre.org/osp/items/detail.cfm?ID=7365Step 3: Run the tracker program. Click on the “Video” tab on the menu bar and from the drop-down menu select “Import”. Use the “Look In” drop down menu to find the video clip that you had saved on your computer in Step 1, once you select the video clip, click on “Open”. It may take a few seconds to load the video. Step 4: Click on the green play button below the video to watch the clip in slow motion. Notice the frames number is displayed in red at the lower left corner as the frames pass in front of you. Step 5: Once you have watched the video, drag the frame slider to the right until you get to the frame number 171. Notice that the ball has left the person’s hand in this frame. Right click on the slider and from the drop-down menu select “Set start frame to slider (171)”. You will notice an arrow appear below the slider at frame number 171. Now click on the sliding bar to the right of the slider and move through the frames until you get to the frame number 234. Right click on the slider and from the drop-down menu select “Set end frame to slider (234)”. This is where the ball is about to hit the floor. We are going to study the motion between frames 171 and 234 for this lab. Step 6: Drag the slider back to frame number 171. Click on the coordinate axis symbol to set the origin from the experiment. This will display the origin somewhere random on the video. Drag the origin using your mouse and place it exactly at the center of the ball. The ball is rather small so it might be difficult to know exactly where the center is. To be precise, right click on the video near the ball and click on “Zoom in”, this will zoom into the video, set the origin at the center of the ball. Once done, click on the coordinate axis symbol on the top horizontal menu again, this will hide the coordinate axis. Step 7: Staying zoomed in, click on the vertical bar to scroll up the video screen until the entire meter stick attached to the wall in the video (beside the door) is in your view. Step 8: Click on the “calibration tools” icon and from the drop-down menu select “New

The tallest volcano in the solar system is the 30 km tall Martian volcano, Olympus Mons. An astronaut drops a ball off the rim of the crater and that the free fall acceleration of the ball remains constant throughout the ball’s 30 km fall at a value of 3.2 m/s . (We assume that the crater is as deep as the volcano is tall, which is not usually the case in nature.)Find the time for the ball to reach the crater floor.Answer in units of s.
