Faça um pêndulo leve com um pequeno ímã em sua extremidade. Um eletroímã adjacente conectado a uma fonte de corrente alternada de frequência muito superior à frequência natural do pêndulo pode levar a oscilações não-amortecidas com várias amplitudes. Estude e explique o fenômeno.

Exam Software is a Test Management Software, which offers a complete solution for Computer Based Test (CBT).They are used to set up multiple choice tests for set time periods that when submitted are automatically corrected and the results logged beside the student's reference number.
“Demo” user can only take part in quiz.
“Admin” user can enter, modify the quiz questions and mark the correct choices. “Admin” can also take quiz .
To get the correct answer one must ask the correct question. In the field of Quantum Gravity the question has been how do we quantize General Relativity or derive a quantum theory which becomes General Relativity at low energies. Observing that Quantum Field Theory was the result of making Quantum Mechanics into a relativistic theory, I asked myself why not make QFT obey the principles of GR? I answered this question with a model I call Relativization. In a series of three papers I presented an answer to this alternative question which gives finite results for everything from black holes to particle physics.
