Top Questions

1.Please check options and pictures within the file attached. If the questions can be answered within a free demo session ...

hin a free demo session as I have my answers, but just want to confirm them, that would be greatly appreciated. Question 1: A block of mass M = 0.10 kg is attached to one end of a spring with spring constant k = 100 N/m . The other end of the spring is attached to a fixed wall. The block is pushed against the spring, compressing it a distance x = 0.04 m . The block is then released from rest, and the block-spring system travels along a horizontal, rough track. Data collected from a motion detector are used to create a graph of the kinetic energy K and spring potential energy Us of the system as a function of the block's position as the spring expands. How can the student determine the amount of mechanical energy dissipated by friction as the spring expanded to its natural spring length? Question 2: The Atwood’s machine shown consists of two blocks connected by a light string that passes over a pulley of negligible mass and negligible friction. The blocks are released from rest, and m2 is greater than m1. Assume that the reference line of zero gravitational potential energy is the floor. Which of the following best represents the total gravitational potential energy U and total kinetic energy K of the block-block-Earth system as a function of the height h of block m1? Question 3: A 2 kg block is placed at the top of an incline and released from rest near Earth’s surface and unknown distance H above the ground. The angle θ between the ground and the incline is also unknown. Frictional forces between the block and the incline are considered to be negligible. The block eventually slides to the bottom of the incline after 0.75 s. The block’s velocity v as a function of time t is shown in the graph starting from the instant it is released. How could a student use the graph to determine the total energy of the block-Earth system? Question 4: A block slides across a flat, horizontal surface to the right. For each choice, the arrows represent velocity vectors of the block at successive intervals of time. Which of the following diagrams represents the situation in which the block loses kinetic energy?

2.Hi, I need help with correct and edit free writings. Please see below. “Hi Aunty Anne, I have two questions ...

I have two questions for you. I’m not sure how you paid for Walmart and CVS last year. When I made copies of receipts. I found out that you swapped the check 1234 $200.00 from Walmart to CVS. I just entered the amounts from Paid Receipts Report on form A For Form B, I don’t see any box for 1-HP. Is it okay to add total form 1-ST and 1-HP together? Please let me know what your thoughts are. Thank you for your help.” " James, how come you ate lunch late? Eating late lunch is not good for you. Tell me what your favorite food is and i will treat you lunch one day after COVID is over" “ Are you eating Korean food? You make me feel hungry. I love to eat beef tongues and chicken bbq. I wish I could sit next to you. ” “ Thank you for sharing the information. You are the best teacher in the world.”

3.Macroeconomic powerpoint presentation on Inflation vs deflation. Below is the Assignment description: This course has a Final Project which is ...

: This course has a Final Project which is in the form of a PowerPoint presentation (you may also use Google Slides). You can choose a topic from this semester or something you come up with yourself, but your presentation must be about economics and be original (i.e. not just material verbatim that you have pulled from your text/readings or off the internet). Of course, you can still insert charts, graphs, videos, graphics and excerpts from outside sources (as long as you cite those sources!) I want to see your commentary and analysis, in your own words. IMPORTANT: Copying the work of others and representing it as your own (ex. copy and paste off of the internet or your text, OR using someone else's work and just changing a few words) is Plagiarism, a serious academic offense. I have enabled the Turnitin plagiarism checker for this assignment, to help you identify potential areas of plagiarism. Papers that are substantially plagiarized will NOT be accepted for grading. Although the format is a Power Point, I want to emphasize that this is NOT like your typical Power Point, which is basically an outline for a live presentation. Your project must be substantially loaded with content. The first slide should be your Introduction slide, the next 10-15 slides should be informational slides, the second to last slide should be your conclusion (which summarizes your presentation) and the last slide should be the reference slide. Make sure you review the rubric below BEFORE you start your project, so that you are clear on how your project will be graded. NOTE: The due date is Wednesday, 12/16. A 20% late penalty will be assessed every day for assignments submitted past this date. PLEASE contact me if you have any questions about the requirements of this project, plagiarism, citations...or any other concerns!

4.I have 5 questions I am stuck on. Please help! 1. Enter the correct answer in the box. Facundo crochets and sells ...

chets and sells baby blankets, b. Each blanket requires 3 skeins of yarn, and the total number of skeins Facundo uses, y, varies directly as the number of blankets he crochets, b. Write an equation that models this relationship. 2. The weight of an object, w, varies inversely as the square of its distance from the center of Earth, d. When an astronaut stands in a training center on the surface of Earth (3,960 miles from the center), she weighs 155 pounds. To the nearest tenth of a pound, what will be the approximate weight of the astronaut when she is standing on a space station, in orbit 240 miles above the training center? 3. The square of g varies inversely as h. When g = 16, h = 2. What is the value of h when g = 40? 4. The number of days, d, it will take Manny to read a book varies inversely as the number of pages, p, he reads per day. If k is the constant of variation, which equation represents this situation? 5. The battery life for Bruhier’s cell phone is longer when he has fewer apps running. When only one app is running, the battery will last for 16 hours. When four apps are running, the battery will only last for 4 hours.

6.Statistics questions help please! I have three questions High levels of cholesterol in the blood are linked to a higher risk ...

d are linked to a higher risk of developing coronary heart diseases. A researcher is investigating two types of interventions (e.g. A, B) to reduce the cholesterol level. Study participants were randomized to receive either intervention A or B. Some subjects dropped from the study due to reasons not related to the interventions. In order to determine which intervention was more effective, the mean cholesterol concentrations were compared between the two groups at the end of the study. The total cholesterol levels for the patients undergoing the intervention A were: 240, 238, 245, 256, 289, 190, 189, 205, 200, 214, 237, 247, 254, 209, 211, 200 mg/dl. The total cholesterol levels for the patients undergoing the intervention B were: 213, 188, 199, 247, 248, 239, 256, 244, 206, 223, 241, 261, 226, and 231 mg/dl. Which intervention was more effective? Consider alpha=0.05. Intervention B was more effective. Intervention A was more effective. Impossible to tell based on the information provided. The two interventions were not statistically significant different.
