You are investigating two sensors to use in an experiment.
Sensor A has area 600 ± 0.3 mm2 and the gap thickness is 0.3 ± 0.01
mm. Sensor B has area 400 ± 0.25 mm2 and the gap thickness is 0.2 ±
0.02 mm. Estimate the relative (hint: this is a %) and absolute
uncertainties (hint: this has units of capacitance) in capacitance
for both sensors. Your experiment requires that the capacitance is
measured accurately within 5%. Which would you...

a) Compute the sensor sensitivity using the data off the table
1?
b) Study the sensor linearity based on the data of the table
1?...
2.) Describe and show your calculations how you will make a 50
mL solution of an ammonia buffer where pH = 10.07 and [NH3] +
[NH4+] = [NH4]T = 10.2 M using concentrated ammonia (28.0% by
weight) and ammonium chloride.
Can you show me how to use Excel to do the
calculations?
Sam Strother and Shawna Tibbs are vice presidents of Mutual of
Seattle Insurance Company and co-directors of the company’s pension
fund management division. An important new client, the
North-Western Municipal Alliance, has requested that Mutual of
Seattle present an investment seminar to the mayors of the
represented cities, and Strother and Tibbs, who will make the
actual presentation, have asked you to help them by answering the
following...
Smart sensor nodes can process data collected from sensors, make
decisions, and recognize relevant events based on the sensed
information before sharing it with other nodes. In wireless sensor
networks, the smart sensor nodes are usually grouped in clusters
for effective cooperation. One sensor node in each cluster must act
as a cluster head. The cluster head depletes its energy resources
faster than the other nodes. Thus, the cluster-head role must be
periodically reassigned (rotated) to different sensor nodes to...
(1) You are estimating the cost of optical sensors based on the
radius of the sensors. You decide to calculate the coefficient of
determination (R2) as part of determining the goodness of fit of an
equation. Using the preliminary calculations below, calculate the
R2 and determine its meaning. [Image Description: Summation of
(Yi-Ybar)2 = 150000, Summation of (Yhat-Ybar)2 = 125000, Summation
of (Y-Yhat)2 = 25000]
16.67% of the variation in the radius is being explained by the
cost.
