the positive supply and pin 1 is grounded. To detect the present of an object we have used LDR and a source of light. LDR is a special type of resistance whose value depends on the brightness of the light‚ which is falling on it. It has resistance of about 1 mega ohm when in total darkness‚ but a resistance of only about 5k ohms when brightness illuminated. It responds to a large part of light spectrum. We have made a potential divider circuit with

Does peaceful resistance to laws positively or negatively impact a democracy? Civil disobedience is a form of peaceful political protest in an active opposition to comply with certain laws considered unjust while accepting the consequences. Within the history of the United States of America three instances that support that civil disobedience impacts a free society positively consist of a paper by Harris g. Mirkin known as Rebellion‚ Revolution‚ and the Constitution "Thomas Jefferson’s theory of

(United States House of Representatives). Antibiotic resistance is when bacteria develops a different response to an antibiotic that is its ancestor bacteria. Slight changes in bacteria enable the antibiotic to work and successfully cause an infection without a remedy. The misuse of antibiotics is the number one cause of bacteria resistance to antibiotics (United States House of Representatives). I will talk about how bacteria develop antibiotic resistance‚ how it affects doctors and patients‚ and how to

Account for the motives that led him to shoot. Then categorize them as personal motives‚ circumstantial motives‚ social motives‚ or political motives. Is it easy to assign his motives to categories? Why or why not * Orwell did shoot the elephant because he felt the pressure that came from thousands of native people behind him when he

culture results return. The problem with the misuse of broad spectrums is the resistance it can cause. The good thing about the narrow spectrum is that it covers for the specific organism that is causing the infection. The problem is that treatment for the wrong organism can occur. 3.

Some common mechanisms by which antimicrobial resistance emerges are incomplete dosing where the bacteria adapts‚ random mutations that

or we hear it at school‚ resistance it seems to be happening more and more these days. Most of the resistance that I have seen‚ watched‚ or heard about lately has been centered around our new President‚ Donald Trump. Most of these protest or resistance to laws or resistance to change or even resistance to changing the laws‚ there have been no in-between on sides or passion. We have either seen peaceful resistance or an all outright very violent and destructive resistance. Both sides‚ peaceful &

experiment is to test the predictions for current‚ voltage and resistance of the relationships of parallel and series circuits. The procedures strive to prove that the theoretical outcomes are consistent with the corresponding measured results. After setting up the closed circuits we want to test our own results into the equations and conclude if they are true. In the same circuit‚ there are specific equations that show how current‚ resistance and voltage behave. The equations or predictions differ
