Nciado: frequentemente, em ciências exatas, utilizamos potências de base 10 para expressar números muito grandes ou muito pequenos. para as potências de base 10 mais utilizadas foram desenvolvidos os prefixos e símbolos. por exemplo, o prefixo centi (simbolizado pela letra minúscula c) se refere à potência 10-2. então, se fizermos uma medida de 0,01 metro, ela poderá ser escrita como 1.10-2m ou, então, como 1 cm (um centímetro). existem vários outros prefixos, é importante saber usá-los corretamente e adotar a simbologia adequada. dentre as opções abaixo, qual seria a opção correta para escrevermos a medida de 30 000 gramas (g) em potência de base 10? escolha uma:

Hi. The language here looks as though it's Spanish/Portugese ??? It would help to answer the q if the q were posted in english. I speak a little spanish and french, but it's mostly guesswork.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
