Different ways of speaking are part of gender. As adults, men and women sometimes face difficulties in their communication with each other. Studies of communication show that if a woman tells her husband about a problem, she will expect him to listen and offer sympathy.

Then one day, after he had finished counting his money, he thought that he could get all the Golden eggs at once by killing the Goose and cutting it open. But when he killed her, he didn’t find a single Golden egg and his precious Goose was dead.

Durante um experimento foi elaborado um gráfico da intensidade da força horizontal resultante (F) aplicada sobre um bloco que se desloca (d) sobre um plano horizontal, conforme é mostrado na figura a seguir. Determine o trabalho, em joules, realizado pela força resultante durante todo o deslocamento.

Duas cargas elétricas puntiformes de mesmo valor e de Rascunho sinais contrários são colocadas a uma distância fixa. No ponto médio entre elas, mede-se a intensidade do vetor campo elétrico e o potencial elétrico. Assinale a alternativa que contém os resultados corretos para essas medidas.
