2022 Lab 7 - Forces in Every Life

Newton’s 2nd Law Lab (Modeling­ friendly lab)   Go to the PhET simulation Forces & Motion. https://phet.colorado.edu/sims/html/forces­and­motion­basics/latest/forces­and­motion­basics_en.html Select “Acceleration” Click to show Forces, Sum of Forces, Values, Mass, and Acceleration. There are two experiments for this activity – make sure you include both.   Experiment #1: Acceleration vs. Force In this lab you will determine the relationship between acceleration and net force. Choose a mass at the beginning, and keep it constant for this entire experiment. Set the friction to zero.  This will make your Applied Force equal to the net force. Record data for five different values of Applied Force. Graph Acceleration vs. Net Force. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Applied Force information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best –…

You have been asked by your supervisors at A&L Engineering to design a roller coaster for a new theme park. Because this design is in the initial stages, you have been asked to create a track for the ride. Your coaster should have at least two peaks and two valleys, and launch from an initial height of 75 meters. Each peak and valley should represent a vertical change of at least 20 meters. In your design, you should plan for a mass between 400 and 600 kilograms. Once you have designed the track, you have been asked to calculate the kinetic energy, potential energy, momentum, and work done by the cart at various points throughout the track. Unless otherwise stated, you can ignore the effects of friction. Following your calculations, you have been asked to describe the energy transfers detailed by these equations. Directions To complete this roller coaster design report, complete the following: Create a diagram of a roller coaster track containing at least two peaks and two…

Hello tutors, help me. Just answer "Let Us Try"

I thought the letters represented the connection between the forces and magnitude. Can you help me truly understand how to evaluate this correctly? Thanks

1) A low-friction cart is placed between two identical springs attached to rigid walls. If you push the cart against one of the springs and release it, it will continue to move back and forth between the springs. www Draw a force-time graph showing the sum of the horizontal forces exerted on the cart as it moves back and force between the springs. Scientific Abilities Is able to construct a force diagram Missing No representation is constructed. Inadequate FD is constructed but contains major errors such as incorrect mislabeled or not labeled force vectors, length of vectors, wrong direction, extra incorrect vectors are added, or vectors are missing. Needs Improvement FD contains no errors in vectors but lacks a key feature such as labels of forces with two subscripts or vectors are not drawn from single point, or axes are missing. Adequate The diagram contains no errors and each force is labeled so that it is clearly understood what each force represents. Explain whether or not this…

Suppose a flu epidemic has broken out in all math 1215 courses at your school. Assume a total of 24 people have the flu as of today and that each day the total number people who have the flu double. Let f(t) represent the number of people who have the flu at t days since today. Estimate numerically when the number of people will reach 768. {your final answer just number}

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…

Please show work in a handwritten format. Don't use chatgpt. Mechanics of materials/design.

You are assigned as the head of the engineering team to work on selecting the right-sized blower that will go on your new line of hybrid vehicles.The fan circulates the warm air on the inside of the windshield to stop condensation of water vapor and allow for maximum visibility during wintertime (see images). You have been provided with some info. and are asked to pick from the bottom table, the right model number(s) that will satisfy the requirement. Your car is equipped with a fan blower setting that allow you to choose between speeds 0, 1,2 and 3. Variation of the convection heat transfer coefficient is dependent upon multiple factors, including the size and the blower configuration.You can only use the following parameters:

Thermodynamics Please READ THE PROBLEM! I’m tired of posting the same problem over and over. please Read. This is what the asking for please: -1. sketch and label all your answers on the nozzle -2. Sketch and label all your answers on the process on a P-V diagram.... Thank you

Follow the instructions carefully.

Astronomy Question:  Read the questions slowly and answer with precise and long details about each of the questions. Answer correctly and follow my guidelines for a long and wonderful review after results. Your target/main observable galaxy is the whirlpool galaxy. Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes Venatici. DO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words.Provide refernces if used In 500 words, please explain the relevance of this object to the physics course material in university andits importance to astronomy. (Some question you may seek to answer are: What beyond the objectitself is learned by studying this class of objects? What sorts of telescopes and observations would beneeded for more detailed, broader reaching studies of this source and objects of its nature?)

I need help with this before tomorrow’s exam if I can get all needed calculations please

Pl:1: this was all information that was given to me. If need j would need to look it up online.

Don't use chatgpt will upvote

Can i get help with these questions

Please only answer STEP 2 question. THIS IS MY 3RD TIME POSTING THE SAME QUESTION AND NOT GETTING THE ANSWER I NEED. DONT SOLVE FOR THE MAIN QUESTION, I NEED THE ANSWER TO THE SECOND PART OF THE QUESTION ONLY.

Hello I have two pictures with some questions Id like to get answers to! Short and great explanations please thank you !

Motiyo   Add explanation

Please answer this and in full sentences. Please and thank you
