Answer the following questions, to test your understanding of sampling frequency and bit depth. 1. You are part of new automobile design team, and are responsible for designing the sensor data collection system. The specification of the data collection system is that is must be capable of receiving data with a resolution down to 0.1% of full scale (1 part in 1000) for any given sensor. For example, suppose the driver pushes the gas pedal, the motion of which is read by an electronic sensor such that the range of motion is defined from 0 (not pressed) to 1 (fully pressed). If you want 0.1 % accuracy, you need 1000 possible data values between 0 and 1. How many bits do you need to represent data to 0.1% accuracy? Insert a picture of your work.

You’re testing a system that involves a fan, water pump, and compressor. The components are turned ON in sequence and sensor readings are taken, as per a written protocol that you’re following. The system is running as expected after the fan and water pump are turned ON. However, when you turn ON the compressor, it runs for about thirty seconds then stops, consistently. Swapping out the compressor for a different one seems to solve the problem. What could have been the issue with the bad compressor?

Instrumentation & Measurements This homework measures your capability to design/analyze various components/variables of ameasurement system based on what you have studied. Question is Attached in image. Thank you.

A chamber of unknown volume is filled with an unknown amount of ideal gas. A cylinder with an open bottom and calibrated volume is connected to the chamber and is closed with a movable piston. A gas pressure sensor is also mounted on the chamber as shown in the figure. The whole experimental setup is kept at a constant temperature of 300 K. Doris moves the piston from mark 0 to mark 200 mL in steps of 50 mL and records the corresponding pressure in the chamber (see the table below). She moves the piston very slowly and waits several minutes before recording the pressure values.   VCyl(mL) P(105N/m2)) 0 4.35 50 3.85 100 3.50 150 3.15 200 2.90   Determine the volume of the chamber using Doris's data in the table. (Note: This is a problem that requires linearization of data.)   Determine the number of moles of gas. (Note: This is a problem that requires linearization of data.)

According to Hooke's Law, we need to be measuring x (the length of the spring) however our CBR is set up to measure y( the height of the bottom of the mass). Create a diagram and explains why we can swap out x variables for y variables when conducting this experiment x y

A. A student establishes the time constant of a temperature sensor by first holding it immersed in hot water and then suddenly removing it and holding it immersed in cold water. Several other students perform the same test with similar sensors. Overall, their results are inconsistent, with estimated time constants differing by as much as a factor of 1.2. Offer suggestions about why this might happen. Hint: Try this yourself and think about control of test conditions. B. Which would you expect to be better suited to measure a time-dependent temperature, a thermal sensor (e.g., a thermocouple) having a small diameter spherical bead or one having a large diameter spherical bead? Why?

6. A ball is thrown straight up in the air at time t = 0. Its height y(t) is given by y(t) = vot - 791² (1) Calculate: (a) The time at which the ball hits the ground. First, make an estimate using a scaling analysis (the inputs are g and vo and the output is the time of landing. Think about their units and how you might construct the output using the inputs, just by matching units). Solve the problem exactly. Verify that the scaling analysis gives you (almost) the correct answer. (b) The times at which the ball reaches the height v/(4g). Use the quadratic formula. (c) The times at which the ball reaches the height v/(2g). You should find that both solutions are identical. What does this indicate physically? (d) The times at which the ball reaches the height v/g. What is the physical interpretation of your solutions? (e) Does your scaling analysis provide any insight into the answers for questions (a-e)? Discuss. (Hint: Observe how your answers depend on g and vo).

I want clear answer to get to the answer of that question

Can someone please help me to answer all of the following questions thank you!!

You are part of a car accident investigative team, looking into a case where a car drove off a bridge. You are using the lab projectile launcher to simulate the accident and to test your mathematical model (an equation that applies to the situation) before you apply the model to the accident data. We are assuming we can treat the car as a projectile.

A snowboarder’s velocity is tracked by a pulse-laser velocimeter as she descends the slope. These velocity data are stored and analyzed via an embedded curve fitting procedure to determine a velocity function of v(t) = 1.5t2 + 2t + 2 (t is time in seconds and v is velocity in ft/s). At time equal 0, position (x) is zero. Find her position (e.g., distance traveled), velocity and acceleration formulations and values of each when time equals 15 seconds. Clearly write the formulas before finding respective values at t = 15 seconds!
