Hi all, I just need help finding B for this Data Set! Any help is appreciated.
A group of students performed the same "Force on a Wire" experiment that you did in class. They obtained the following results.
| Current (mA) | Length (cm) | Force (N) |
|---|---|---|
| 899 | 4.0 | 0.0316 |
| 867 | 3.1 | 0.0237 |
| 888 | 2.1 | 0.0158 |
| 877 | 0.9 | 0.0079 |
(a) Analyze the data. (You will not submit this spreadsheet. However, the results will be needed later in this problem.)
(i) Enter the above data into an Excel spreadsheet.
(ii) Make a plot of force versus length.
(iii) Use the trendline option in Excel to fit the data of force
versus length to get the slope.
(b) Report this value below.
slope = .0076
(c) Now, use the average current to determine the strength of the
magnetic field B in which the experiment was carried
out.
B = ??

In p - V phase diagrams, the slope. (partialdifferential p/partialdifferential V)_T, n, along an isotherm is never positive. Why? Regions where (partialdifferential p/partialdifferential V)_T, n = 0 represent equilibrium between two phases; volume can change with no change in pressure, as when water boils at atmospheric pressure. We can use this to determine the temperature, pressure, and volume per...

Question 3 (24 points) The article 'Drift in Posturography Systems Equipped with a Piezoelectric Force Platform: Analysis and Numerical Compensation' (L. Quagliarella, N. Sasanelli, and V. Monaco, IEEE Transactions on Instrumentation and Measurement, 2008:997-1004) reported the results of an experiment to determine the effect of load on the drift in signals derived from a piezoelectric force plate. The correlation coefficient, y, between output and time was...
