Places for People 2015   As our city continues to grow and change, we invite you to tell us how well your local neighborhood is meeting your daily needs. Thanks to everyone who completed the neighborhood survey. Your local insight will inform our third Places for People study and help us plan for improved neighborhoods. A project update will be provided in the second half of 2015. Prize winners will be notified 14 May 2015. A key aim of our third Places for People study is to understand how people are using the city, to work towards the realisation of liveable neighborhoods, where local goods, services and infrastructure meet people’s daily needs and can be accessed by foot.   Available at:<http://participate.melbourne.vic.gov.au/projects/placesforpeople/>Accessed on: May 24, 2015.   Some places people go in the city are: malls, gymnasiums, post offices, libraries, bookstores, beauty-parlors, parks, etc.   Available at: < www.oxforddictionaries.com > Accessed on: April 5th, 2015.

Considerando que tenham sido baseados em animais reais e de acordo com a atual classificação biológica, pode-se afirmar que: 

(UEFS)

Uma carga  q₁ = +16,0nC está posicionada na origem, e uma segunda carga  q₂ = -25,0nC está colocada sobre o eixo y a uma distância a = -3,0m da origem, conforme mostra a figura. Sabendo-se que a constante eletrostática do meio é igual a 9,0.10⁹N.m²/C², a intensidade do campo elétrico resultante no ponto P sobre o eixo x, em b = 4,0m, em N/C, é de, aproximadamente,
