(b) Solve the circuit. That is find all unknown currents, voltages, and resistances. 6. Consider the circuit in Figure 4, where R1 = 5.00×102Ω, R2 = 1.00×103Ω, and VB = 10.0V . (a) Find the equivalent resistance Req of the circuit.
Determining the mass of the two unknown weights (unknown weight #1 and #2) was determined using only the centigram balance using the weighing by difference method. Unknown weight # 1 had a mass of 24.82 g while unknown weight #2 had a mass of 25.17 g. The average mass experiment was conducted by individually weighing five different copper slugs on an electronic balance, then
It is also given that at t=zero (time=zero) the current is equal to 5 Amps, meaning there is a negative phase shift (or phase shift to the left). A=5 B is calculated by the equation B=2π/( 1/60) , where p (period length)= 1/60 or the length of one full cycle found from the frequency which is 60cycles per second. So p is
5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
The concentration is measured in molarity. Molarity is the measure of moles of solute per liter of solution. The rate law helps one find solution's reaction order. If the reaction order is zero, the graphical representation is concentration vs. time, and the slope of the line is the negative rate constant. If the reaction is first order, its graphical representation is seen as ln[A] (natural log of concentration) vs. time, and the slope of its like is also the negative rate constant.
Body Measurement Experiment Shane Cozort September 27, 2011 Biology 2010-51 Professor Martin Subjects: Gena Lyn, Kayli, Laura Beth, Karen, Morgan, Sara, Taylor, Cassi, Robin, Aaronda, Lauren, Mary Intro/Observations/hypothesis With the correlations among height and limb length, a study was conducted using the Scientific Method to determine if the arm has a direct relationship with the height of the person. The subjects for this study were 1 male and 12 female from Tuesday 1:20pm A&P lab class. These subjects were randomly selected and grouped by Professor Martin. These calculations can be of use in determining skeletal deformities, abnormalities of the spine, or if limb length is predictor of height. The aim of this study is to approve or reject the hypothesis being limb length (arm) is equal to 40% of a person’s height.
EXPERIMENTAL DATA: Table 1: Measured values from experimental data Resistor Measured Value 101 Ω Capacitor 1 μF Amplitude of voltage 5v Phase difference 58.752º Peak to peak voltage 10 v Amplitude of current 2.53 mA ANSWERS TO THE POST LAB REPORT: Q. 1. Dividw the amplitude of the signal generator voltage measured by the oscilloscope by √ and compares it with the measured value by voltmeter. Answer: Here given, Vm = 5 V Dividing Amplitude of voltage Vm by √2, 5 √2 = 3.54 Comment: Both values were not matching. There have more than 10% discrepancy.
Collect 4 small test tubes and weight them. 2. Each student is assigned certain volume of 0.50M Cu(NO3)2 and 0.50M KI. Test tubes 1 and 2 will be duplicates and test tubes 3 and 4 will be duplicates too. Add the volume of each solution assigned.
The absorption spectrum is measured using a spectrophotometer and the data is graphed in Excel. The peak of the line is used to find Vmax of Fe2+. Vmax is used to find the moles of Fe2+ and ligand. The unknown n is a ratio of moles ligand divided by moles Fe2+. Results and Discussion For the first part of the experiment (Part A), five different 100 mL volumetric flasks were each filled with 1,2,3,4 and 5 mL of iron (II) solution.
