then recorded the new volume and subtracted the two recordings equaling the volume of the unknown. 4. We then calculate the density by dividing the mass by the volume. 5. We then remove the metal cylinder‚ dry it and repeat to get the other two densities. Then record the measurements and density for each trial and then average the densities. Part 2: Calibration of a Buret 1. Get 4 small beakers‚ clean and dry them‚ then record the mass of each. 2. Get & Fill the buret past

What are the Effect of Different Environments and the Movement of Pill Bugs? Purpose: The purpose of this lab was to analyze pill bug’s activity in different environments and determine the effect of wet/dry or dark/light environments have on them and how taxis takes place in their choices in living in areas. Background information: Terrestrial isopods are commonly referred to as sow bugs and pill bugs and have other nick names as well. These pill bugs are also related to lobsters‚ crabs and

weight. Let W+AB be the new (trained) weight and WAB being the initial weights. Notice that it is the output of the connecting neuron (neuron A). Update all the weights in the output layer in this way. W+AB= W+AB + ( ErrorB x OutputA) (5.20) 4. Calculate the Errors for the hidden layer neurons. Unlike the output layer it is not possible to calculate these directly (because there is no Target)‚ so Back Propagate them from the output layer (hence the name of the algorithm). This is done by taking

Introduction Electric fields are produced by charges. Charges may be one of two signs‚ positive or negative. Changing the positions of positive and negative charges can alter an electric field. An electric field is a vector quantity from which the magnitude and direction of an electric force is determined. The electric force is due to the presence of charged particles. Charge is the attribute of matter by which matter responds to electromagnetic forces. Charge is responsible for all electrical

string and assign variable X. Step 2 : Each element in input string is converted into ASCII value. Step 3 : If length of the string is even then the string is equally divided into two parts using the left substring and right substring. Step 4 : If the length of the string is odd then middle most elements is kept unchanged with left substring and right substring respectively. Step 5 : Reverse the right substring and then repeat step3 and step4 until the derived two substrings

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze
