← Voltar para a lista de provas Comando da Aeronáutica · Exame de Admissão aos CFOAV, CFOINT e CFOINF 2023 65 questões nesta prova · página 1 de 4 · 63 com gabarito Gabarito disponível Gabarito disponível Gabarito disponível O trecho de Dickens compara o período narrado ao presente do autor. Depois de listar contrastes, o narrador diz que 'the period was so far like the present period'. Isso estabelece uma analogia entre a época da história e a época atual. Ele acrescenta que as autoridades da época a viam apenas em grau superlativo. A) Não se desenvolve a ideia de que 'nada é o que parece'. Há apenas antíteses sobre a época. B) Não há relato de disputas recentes. C) Os 'noisiest authorities' insistiam em um grau superlativo, mas o texto não sugere espaço para debate sobre as comparações. D) Correta, pela comparação explícita entre os dois períodos. Referência: Dickens, A Tale of Two Cities (abertura). Resolução comentada do VaiConcursos. Gabarito disponível Franval tem aparência, talentos e riqueza notáveis, mas esconde vícios. Sua personalidade não corresponde à aparência. O texto diz que Franval tem a melhor figura, o rosto mais agradável e os talentos mais variados. Diz também que, sob essa aparência atraente, escondem-se todos os vícios. Portanto, a personalidade dele contrasta com a aparência, e não corresponde a ela. A) Está no texto: 'the most pleasant face' e 'finest figure'. B) Está no texto: 'the finest figure' quer dizer que nenhuma outra se iguala. C) Está no texto: 'the most varied talents'. D) É a exceção. O texto afirma que sob a bela aparência 'lay hidden every vice', então o caráter não condiz com ela. Referência: Sade, The Gothic Tales of the Marquis de Sade (2000). Resolução comentada do VaiConcursos. Gabarito disponível Ambos os textos apresentam pares de conceitos contrastantes. O Texto II usa antíteses (best/worst, wisdom/foolishness, light/darkness). O Texto III usa pares do tipo 'the less they do, the more they undertake', e a dualidade aparece nos dois. A) Errada: não há consolo nem esperança de futuro imutável. B) Errada: os textos não descrevem as motivações dos personagens por completo. D) Errada: não há ação e violência combinadas. Referência: Dickens, A Tale of Two Cities; Sade, The Gothic Tales Resolução comentada do VaiConcursos. Gabarito disponível 'Meet my fate' alude à morte. 'I know I shall meet my fate somewhere among the clouds' refere-se à sua morte nos ares. É um eufemismo para morrer. B) Errada: 'waste of breath' é inutilidade. C) Errada: 'tumult in the clouds' é a batalha. D) Errada: 'impulse of delight' é o motivo que o levou a lutar. Referência: Yeats, 'An Irish Airman Foresees His Death' Resolução comentada do VaiConcursos. Gabarito disponível Linhas 7-8: nenhum desfecho da guerra os deixará melhores ou piores. 'No likely end could bring them loss / Or leave them happier than before' diz que o resultado da guerra não mudará a vida dos pobres de Kiltartan. Eles ficarão alheios ao desfecho. A) Errada: não há expressão de esperança de sobreviver. B) Errada: o poema não fala em encorajamento. D) Errada: não é tratado o conhecimento dos perigos. Referência: Yeats, 'An Irish Airman Foresees His Death' Resolução comentada do VaiConcursos. Gabarito disponível Linhas 9-12: nenhuma obrigação o levou à guerra, apenas um impulso de prazer. O aviador diz que nem lei, nem dever, nem políticos, nem multidões o levaram a lutar, e que foi um 'lonely impulse of delight'. Ele luta pelo puro prazer e pela emoção. A) Errada: ele rejeita a busca de honra e glória, citando 'public men' e 'cheering crowds'. C) Errada: proteger concidadãos é negado ('Those that I guard I do not love'). D) Errada: 'tumult in the clouds' é o combate real, não um devaneio. Referência: Yeats, 'An Irish Airman Foresees His Death' Resolução comentada do VaiConcursos. Gabarito disponível Corretas: II e III. II: 'must be won', 'my leave' e 'I've got to go home' indicam que o soldado foi convocado, e o gabarito considera a afirmativa correta. III: a linha 4 ('With our soldiers so brave') é frase sem verbo, com partes da oração omitidas. I está errada porque a guerra segue em andamento. IV está errada porque 'have' é auxiliar padrão. V está errada porque 'convictions' é traduzido como 'convicções', logo não é falso cognato. A) Errada: I é falsa. B) Errada: I e V são falsas. D) Errada: IV é falsa. Referência: Text V, New Order, 'Love Vigilantes' Resolução comentada do VaiConcursos. Gabarito disponível 'I've got to go home' é linguagem coloquial. 'Have got to' é a forma coloquial de 'have to'. As outras frases estão em registro neutro. B, C e D) Erradas: construções padrão, sem marca de coloquialidade. Referência: Registro linguístico em inglês: 'have got to' Resolução comentada do VaiConcursos. Gabarito disponível Sequência 5/5/5/4/4. Texto V: o soldado acredita na guerra ('war that must be won', 'in the name of truth') e é dado como morto no telegrama. Texto IV: o aviador não luta por patriotismo nem por ódio, e acha os anos passados e futuros inúteis diante desta vida. Ele pesa passado, presente e futuro. B, C e D) Erradas: invertem as atribuições, por exemplo dão o fervor patriótico ao aviador de Yeats, que declara não odiar nem amar, ou dão ao soldado de New Order a reflexão sobre passado e futuro. Referência: Yeats, 'An Irish Airman Foresees His Death'; New Order, 'Love Vigilantes' Resolução comentada do VaiConcursos. Gabarito disponível Musk é conhecido por frases de efeito que rendem manchetes. O texto diz que Musk é renomado por criar soundbites para a mídia e por causar disrupção calculada no público. Portanto, ele apresenta informações para fazer notícia. A) Errada: o texto diz que a disrupção é calculada, não improvisada. C) Errada: o texto não fala de manter o público atento por meio de planejamento do discurso. D) Errada: ele busca os holofotes, não os desaprova. Referência: Text VI, linhas 7-10 Resolução comentada do VaiConcursos. Gabarito disponível Para Musk, a era dos caças acabou e os pilotos podem se tornar obsoletos. Musk afirma que a era dos caças passou e que o humano na cabine é o fator limitante. Infere-se que os pilotos de caça podem se tornar obsoletos. A) Errada: ele critica o humano na cabine, não busca torná-la mais amigável. B) Errada: ele diz que a era dos caças passou. C) Errada: o controverso é a afirmação dele, não uma nova era de conflitos. Referência: Text VI Resolução comentada do VaiConcursos. Gabarito disponível No futuro, só ser 'a good stick' não bastará, e o piloto precisará de outras qualidades. O texto diz que simplesmente ser 'a good stick' (bom piloto) deixará de ser suficiente nos céus hostis do futuro. Logo, os pilotos terão de contar com outras qualidades além da habilidade técnica. A) Errada: o desconforto do equipamento não é projetado para o futuro. C) Errada: Musk diz que o humano é o fator limitante. D) Errada: decisões de vida ou morte em frações de segundo não são mencionadas. Referência: Text VI, linhas 12-15 Resolução comentada do VaiConcursos. Gabarito disponível I, III e IV são verdadeiras; II é falsa. I: o texto diz que os humanos são difíceis de acomodar para os projetistas, e isso é verdadeiro. II: o texto afirma que o humano é o fator limitante, não a vantagem, então é falso. III: o canopy permite ver, mas prejudica a furtividade, e é verdadeiro. IV: o equipamento adiciona peso e custo, e é verdadeiro. A, B e D) Erradas: classificam alguma afirmativa de forma contrária ao texto, por exemplo tratando II como verdadeira ou IV como falsa. Referência: Text VI (Forbes) Resolução comentada do VaiConcursos. Gabarito disponível 'an' é artigo indefinido que introduz a descrição do chat como informal. Em 'an informal fireside chat', 'an' é artigo indefinido que introduz o substantivo e sua descrição (informal). O gabarito aponta a A como correta. B) Errada: 'a lot' ('a lot simpler') funciona como 'much', e 'very' não modifica comparativos. C) Errada: 'does' em 'does little' é verbo principal, não auxiliar. D) Errada: 'of causing' exige gerúndio após a preposição, e a forma 'cause' não serve. Referência: Classes de palavras: artigos, verbo 'do', gerúndio Resolução comentada do VaiConcursos.

Oh, I’ve just come from the land of the sun
From a war that must be won
In the name of truth
With our soldiers so brave

With our rifles and grenades
And some help from God
I want to see my family
My wife and child waiting for me
10 I’ve got to go home
I’ve been so alone you see
You just can’t believe
The joy I did receive
When I finally got my leave
15 And I was going home
Oh, I flew through the sky
My convictions could not lie
For my country I would die
And I will see it soon
20 When I walked through the door
My wife she laid upon the floor
And with tears her eyes were sore
I did not know why
Then I looked into her hand
25 And I saw the telegram
Said that I was a brave, brave man
But that I was dead

Elon Musk, the CEO of SpaceX and Tesla, caused
something of a stir at the annual Air Force Association’s
Air Warfare Symposium in Orlando, Florida. During an
informal ‘fireside chat’ with Lt. Gen. John Thompson of
5 Space Command on Friday, Musk told a room packed
with fighter pilots that “the fighter jet era has passed”.
Now, Musk is renowned for finding soundbites for the
media to hook onto, and also of causing calculated
disruption in his target audience, but even by his
10 standards this is a well-baited line. What makes this such
a bold and controversial statement?
The contemporary battlefield is far more networked,
complex, congested and lethal – it’s those that adapt that
will survive. Simply being ‘a good stick’ will rapidly no
15 longer cut it in the hostile skies of the future.
Musk’s main thrust is, however, that the human in
the cockpit is the limiting factor in air combat now, not the
advantage.
Firstly, humans are awkward for aircraft designers to
20 accommodate. In a modern fighter the pilot sits on an
ejection seat for emergency escape, needs an oxygen
supply and air-conditioning to function at extremes of
temperature and altitude, and requires flight controls and
instruments to fly and fight the machine. All of these add
25 a significant amount of weight and cost into the aircraft.
Moreover, having a transparent canopy to permit the crew
to see out does little to improve signature management¹
as radar cross section and the chances of reflected sun
glint all increase. The human also adds more weight,
30 especially when encumbered with flight kit such as
helmet, NVGs, g-suit and flight planning and survival
equipment. Traditionally, pilots sit toward the front of the
aircraft to afford them the best view for take-off and
landing, as well as air combat. This has implications on
35 aerodynamics, stealth¹ design and weight distribution
factors. In short, it can make the designers life a lot
simpler if the pilot/crew are not in the aircraft.

Air Warfare Symposium in Orlando, Florida. During an
informal ‘fireside chat’ with Lt. Gen. John Thompson of
5 Space Command on Friday, Musk told a room packed
with fighter pilots that “the fighter jet era has passed”.
Now, Musk is renowned for finding soundbites for the
media to hook onto, and also of causing calculated
disruption in his target audience, but even by his
10 standards this is a well-baited line. What makes this such
a bold and controversial statement?
The contemporary battlefield is far more networked,
complex, congested and lethal – it’s those that adapt that
will survive. Simply being ‘a good stick’ will rapidly no
15 longer cut it in the hostile skies of the future.
Musk’s main thrust is, however, that the human in
the cockpit is the limiting factor in air combat now, not the
advantage.
Firstly, humans are awkward for aircraft designers to
20 accommodate. In a modern fighter the pilot sits on an
ejection seat for emergency escape, needs an oxygen
supply and air-conditioning to function at extremes of
temperature and altitude, and requires flight controls and
instruments to fly and fight the machine. All of these add
25 a significant amount of weight and cost into the aircraft.
Moreover, having a transparent canopy to permit the crew
to see out does little to improve signature management¹
as radar cross section and the chances of reflected sun
glint all increase. The human also adds more weight,
30 especially when encumbered with flight kit such as
helmet, NVGs, g-suit and flight planning and survival
equipment. Traditionally, pilots sit toward the front of the
aircraft to afford them the best view for take-off and
landing, as well as air combat. This has implications on
35 aerodynamics, stealth¹ design and weight distribution
factors. In short, it can make the designers life a lot
simpler if the pilot/crew are not in the aircraft.

Um cilindro, contendo certa massa de gás perfeito, tem um pistão que está ligado a uma mola ideal. Ao fornecer certa quantidade de calor Q, para esse sistema termodinâmico, observa-se uma expansão do gás com a consequente deformação da mola Δx, conforme indica figura a seguir.

Em outro momento, para as mesmas condições iniciais anteriores, ao se fornecer o dobro da quantidade de calor 2Q, a esse sistema, observa-se que a mola sofre uma deformação duas vezes maior, 2Δx.
Considerando que nas duas expansões o sistema tenha sofrido a mesma variação de energia interna e que não houve atrito entre o pistão e o cilindro, pode-se afirmar que a constante elástica da mola vale
