Introduction: The goal of this lab is to use the sensors of the IO Device and an understanding of Newton’s Second Law in order to determine the relationship of force and acceleration. By doing this, the mass of the IO Device can be determined. The following equations will be used: ࠵?

Through several trials, an understanding of the relationship between force and acceleration can be developed and data gathered can be organized such that meaningful conclusions can be drawn. It is expected that that as force increases, acceleration does as well. Procedure: “Time and Magnitude Section” (Part 1) 1.

A. A customer asked you to explain your choice of a temperature sensor that you used for his PCB.
Initially, there were two sensor options. To compare between them, you decided to test their accuracy
and precision. Accuracy of a sensor is a measure of how near its reading is to the real value, the nearer
the measured value to the real value the better. While precision is a measure of how widely spread the
readings of a sensor are [relative to each other] when measuring the same variable, the narrower the
spread the better. So, you tested the two sensors by measuring the same temperature, which was 100
C of boiling water, and you recorder the following 10 measurements of each sensor. Which Sensor has
higher accuracy, and which one has higher precision.

Context
The needle of a sewing machine makes a repetitive up and down motion which is described by the equation
y(t)=Acos(wt)
To choose the settings of the device that will ensure that the needle successfully pierces the textile, you are asked to model the speed in ? of the needle as a function of time.
Constraints and information
The parameter A represents the range of motion (in m);The parameter w represents the angular frequency. It tells us about the number of back and forth movements that the needle makes per second;The parameter w is given in rad/s, so your calculator absolutely must be in radians mode to do the calculations in this problem;Modelization
Establish the model for the y velocity of the needle as a function of time and the parameters A and w.
Then test your model by calculating the speed in y of the needle at the moment and with the given parameters:
Moment: 4.1 s
Amplitude: 0.012 m
Angular frequency: 17.9 rad/s

Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires.
Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C.
When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew?

Then test your model by calculating the speed in y of the needle at the moment and with the given parameters: Moment: 4.1 s Amplitude: 0.012 m Angular frequency: 17.9 rad/sarrow_forward۱:۳ ۳ من Asiacell l. joined the meeting sula äibt Jgsso Lecture (5).pptx - Microsoft PowerPoint Animations Slide Show Review View IIA Text Direction - Shape Fill- A Fi 32, AA =,三,|评一前。 AZLOG Align Text- Convert to SmartArt { }* Shape Outline Re Arrange Quick Styles Drawing Aa A Shape Effects- A Se Font Paragraph Ed Engineering Mechanics Statics (Equilibrium of a Particle) Ayad A.

- otINote: The notation from this problem is from Understanding Cryptography by Paar and Pelzl. We conduct a known-plaintext attack against an LFSR. Through trial and error we have determined that the number of states is m = 4. The plaintext given by when encrypted by the LFSR produced the ciphertext 01011000 = yo yı y2 ys Yo Y %3D What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g. 0101 to represent py = 0, P = 1, P = 0, Po= 1).arrow_forwardA mechanic changing a tire rolls a wheel along the ground towards the car. The radius of the wheel is 42cm, and the speed of the wheel as it rolls is 2 revolutions per second. Height Above Ground (m) radiu HIDE wheel spet Time The diagram above illustrates the vertical motion of a point on the tire over time. It is possible to model the height of this point using a sinusoidal function of the form h(t)=-a sin[b(t-c)]+d. a) Determine the length of time required for one revolution of the tire. b) State the numerical value for each of the parameters a, b, c & d. And write a function representing the motion of the point in the form h(t)= -a sin[b(t−c)]+d.arrow_forwardHW_5_01P.pdf PDF File | C:/Users/Esther/Downloads/HW_5_01P.pdf 2 Would you like to set Microsoft Edge as your default browser?
