Journal ArticleDOI
Electromagnetic braking: a simple quantitative model
TL;DR: In this article, the terminal velocity of a cylindrical magnet falling through a long copper or aluminum pipe is calculated using Faraday's and Lenz's laws, and the experiment and the theory are presented.
Journal ArticleDOI
Exame Nacional do Ensino Médio (ENEM): Uma análise crítica
TL;DR: Achlioptas et al. as mentioned in this paper define a diversidade, i.e., a set of factors that determine a student's ingresso to a selecao, which can be divided into two categories: habilidades cŕiticas and deducao.
Journal ArticleDOI

Fernando Lang da Silveira,Cristiane F. Petry,Dirce Pozebon,Sibele B. C. Pergher,Chaline Detoni,Fernanda Chiarello Stedile,João Henrique Zimnoch dos Santos +6 more
TL;DR: In this article, a series of hybrid supported catalysts were prepared by sequentially grafting Cp2ZrCl2 and nBuCp 2ZrCL2 onto alumino-silicates (MCM-41, SBA-15, MCM-22, ITQ-2).
A insustentabilidade da proposta indutivista de "descobrir a lei a partir de resultados experimentais"
TL;DR: In this article, an exemplo de pratica de laboratorio usualmente realizada nas aulas de Fisica, a "descoberta da Lei do Pendulo Simples", is described.

Fernando Lang da Silveira,Gilvan P. Pires,Cristiane F. Petry,Dirce Pozebon,Fernanda Chiarello Stedile,João Henrique Zimnoch dos Santos,Arnaud Rigacci +6 more
TL;DR: In this paper, a series of hybrid supported catalysts were prepared by sequentially grafting Cp 2 ZrCl 2 and ( n BuCp) 2 ZRCl 2 (1:3 ratio) onto synthesized xerogel, aerogel and commercial silicas.
