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.

(Input all amounts as positive values. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Omit the "$" sign in your response.)

Under the assumption that current and voltage are both sinusoidal functions of time (t, in seconds) and both have the same frequency of 60 cycles per second (period=1/60), let C be the current in Amperes (Amps) with a maximum current of 5 Amps at zero seconds (t=zero). Let V be the voltage that is “leading” the current (‘leading’ corresponding to a negative phase shift) by .003 seconds, meaning voltage reaches its maximum of 180 volts .003 sec before the current reaches its maximum. Both functions begin at zero- there are no phase shifts. Question 1, Part A. Current as a function of time: Based upon the given information, we will be determining the Amplitude (A), period (and thus, B), and the phase shift (C).
The last is dam failure floods, which is when a dam gives way. Artificial levees built by man cannot always withstand periods of extreme flooding and can cause flash floods when they give way. Man made dams can do the same thing when they give way and create large amounts of damage. Altering of a stream channel in order to control the speed of the flow of water can cause bank erosion and damage to bridges and surrounding areas. Land use and other human activities also influence the peak discharge of floods by modifying how rainfall and snowmelt are stored on and run off the land surface into streams.
Influence of Blasting-Induced Vibration on Slopes’ Stability Introduction Slope stability is the potential of slopes to withstand and undergo movement. The balance of shear stress and shear strength determines the stability. A previously stable slope may be initially affected by preparatory factors, making the slope conditionally unstable. Triggering factors of a slope failure can be climatic events can then make a slope actively unstable, leading to mass movements. Mass movements can be caused by increases in shear stress, such as loading, lateral pressure, and transient forces.
2. What is the approximate signal level of the noise floor? 2.4GHz band noise floor is -85db, 5Ghz band noise floor is -100db mark. 3. Of the 11 channels being displayed which ones have the lowest noise floor?
The harmful effects of fracking need to be stopped, but only if we understand what damage occurs during this process so that we can come up with solutions to save drinking water. While groundwater is contaminated by many environmental factors such as automobile exhaust, evidence has suggested that fracking is also responsible for the pollution. According to John Manuel, a regular contributor to the online journal Environmental
The PPD is an index that establishes a quantitative prediction of the percentage of thermally dissatisfied people who feel either too cool or too warm. Fig. 8 shows the PMV and PPD for all three cases. For the calculation metabolic rate and clothing value are assumed 1.2 and 0.8 respectively. Figure 8 is about here As shown in Fig.
In order to convert the power to a voltage adapted to the transmission grid, there cables that link all the transformation units and the turbines. The following figure shows the layout of the internal grid of the Khalladi WF: (figure 8) From the figure above, it can noticeable that the WF is divided in radials, however, it is not always the case. These radials are cables and groups of turbines that are attached to the transformer by a different connection point. The number of turbines in each radial is defined by the maximal power that the final cable can handle. Losses in the
