Para pesquisar a profundidade do oceano numa região, usa-se um sonar instalado num barco em repouso. o intervalo de tempo decorrido entre a emissão do sinal (ultrassom de frequência 75 khz) e a resposta do barco (eco) é de 1 s. supondo o módulo de velociade de propagação do som na água igual a 1,5x103 m/s, qual é a profundidade do oceano, na região considerada?
