It has a better look and more informative illustrations.
It was made for students who really have difficulties with Physics and Mathematics concepts, always trying to explain the smallest details.
It doesn’t just include formulas, always trying to show their origins and uses.
Whenever necessary, he tries to explain through drawings and illustrations.
Don’t skip steps explaining sequence by sequence.
There is a great deal of concern that the student understands the solutions. The teacher puts himself in the student’s shoes.
It often provides information beyond what is necessary for the resolutions, but is useful for future entrance exams.
And much, much more.

On the training trip that takes place annually, the Training Ship Brazil (U27) was docked in the port of Baltimore, in the United States (USA).
To carry out the balance of a cold storage room, that is, to carry out the countable balance of the food in the compartment, the Paymaster, the military officer responsible for carrying out this task, no longer has his digital scale to carry out the “weighing” of the items due to a fault in the panel, caused by a power surge.
He then decided to take measurements using a spring and a ruler, noting the length of the spring at each “weighing”.
To graduate your new force measuring device, you decide to check the extension of the spring for a piece of meat with a known weight of 2.0 N, and you notice an extension of 3 cm of the spring.
It is assumed that the improvised device operates within the proportionality limit.
In a new measurement, a spring extension of 9 cm was found .
So, what is the weight of this last measure?
(A) 4N
(B) 6N
(C) 8N
(D) 10N
(E ) 12

When trying to bring a buoy onto the ship, the soldier pulling it realized too late that the knot connecting the cable to the buoy was loose and was unable to stop it from falling into the sea.
The soldier noticed, looking from the ship, that a third of the buoy’s surface was out of the liquid.
Mark the approximate density of the body in relation to the liquid:
(A) 0.23

There is a rule of thumb used by Navy Divers that says that for every 10m of depth in the water the pressure increases by one atmosphere.
A Sub-Officer Diving (SO-MG) with considerable experience in the profession performs a dive in the
seabed at 40m depth .
Determine the total pressure on the seabed and select the correct option.
(A) 4 atm
(B) 5 atm
(C) 6 atm
(D) 7 atm
(E) 8 atm
Pelo enunciado, cada 10 m de profundidade na água a pressão devido a coluna líquida (pressão hidrostática) aumenta em uma atmosfera.
Como o suboficial mergulhador está a 40 m de profundidade ele suporta uma
pressão hidrostática de 4 atmosfera ( 4 atm).
Mas, essa pressão deve ser acrescida da pressão atmosférica exercida pelo ar na superfície da água que é de .
Assim, a pressão total suportada pelo suboficial mergulhador será de Pt = 4 atm + 1 atm = 5 atm.

Visando a ter um maior controle dos eventos que ocorrem numa determinada Organização Militar (OM), o Oficial encarregado da Sala de Estado, compartimento que dá acesso à Organização, resolve instalar um espelho convexo no alto da referida Sala.
Com relação aos espelhos convexos é correto afirmar que formam imagens:
(A) reais localizadas entre o centro e o foco do espelho.
(B) reais localizadas entre o vértice e o foco do espelho.
(C) reais localizadas na superfície do espelho.
(D) virtuais localizadas na superfície do espelho.
(E) virtuais localizadas entre o vértice e o foco do espelho.
Espelho convexo — Para qualquer localização do objeto
Para qualquer posição do objeto, a imagem terá sempre:
Natureza – virtual
Localização – atrás do espelho e entre V e F e observe que à medida que o objeto se aproxima do espelho, a imagem também se aproxima e aumenta de tamanho, mas está sempre entre V e F.
Tamanho – menor que o do objeto
Orientação – direita em relação ao objeto
Utilidades: Os espelhos convexos são empregados como retrovisores em veículos,
cabines de segurança, elevadores, etc.
Sua vantagem sobre o espelho plano, nesse particular, é ter maior campo visual. Têm, entretanto, o inconveniente de não darem noção da distância.

Um militar, embarcado em uma lancha da marinha atracada a um cais, contou 20 (vinte) pequenas ondas que passaram pelo referido cais em 1 (um) minuto.
Admite-se que a periodicidade do movimento ondulatório foi constante.
Determine a frequência aproximada dessas ondas, e marque a opção correta.
(A) 0,05Hz
(B) 0,33Hz
(C) 0,50Hz
(D) 0,55Hz
(E) 1,00Hz
A frequência (f) representa quantas oscilações completas uma onda efetua em cada unidade de tempo, ou ainda, quantos comprimentos de onda passam por um ponto da onda em cada unidade
de tempo.
Exemplo: Se a frequência de uma onda for de 60 Hz, isto significa que a fonte ou qualquer ponto desta onda oscila 60 vezes em cada segundo.
São dados:
Número de oscilações n = 20 oscilações
Intervalo de tempo ∆t = 1 minuto = 60 s
Então f = �ú���� �� ������çõ�� ������������������ �� ����� = �∆� = 2060 f = 0,33 Hz (oscila ‘sobe e desce” 0,33 vezes em cada segundo)
