Em uma aula de laboratório de Física, para estudar propriedades de cargas elétricas, foi realizado um experimento em que pequenas esferas eletrizadas são injetadas na parte superior de uma câmara, em vácuo, onde há um campo elétrico uniforme na mesma direção e sentido da aceleração local da gravidade. Observou-se que, com campo elétrico de módulo igual a 2 x 103 V/m, uma das esferas, de massa 3,2 x 10-15 kg, permanecia com velocidade constante no interior da câmara. Essa esfera tem: (adote: carga do elétron = -1,6 x 10-19 C carga do próton = + 1,6 x 10-19 C aceleração local da gravidade = 10 m/s2)

Jeremy planned to read the following poem aloud: wisdom by sara teas daleit was a night of early spring, the winter-sleep was scarcely broken; around us shadows and the wind listened for what was never spoken.though half a score of years are gone, spring comes as sharply now as then— but if we had it all to doit would be done the same again. it was a spring that never came; but we have lived enough to know that what we never have, remains; it is the things we have that go. jeremy interpreted this poem to mean that certain people, places, 'and things are important to us in our lives. but as time passes, we lose those things. what technique could jeremy use when reading the poem to emphasize this idea for listeners? a.he could read the poem rapidly to show how quickly people lose what’s important to them. b.he could emphasize the rhyming pattern in each stanza to represent patterns in life. c.he could read the poem slowly to represent the changes that happen over a lifetime. d.he could raise and lower his voice to represent the good and bad things people face in life.
