Aviões não podem pousar em qualquer pista. A extensão da pista, bem como a massa total do avião, influenciada por sua carga e pela quantidade de combustível no tanque, podem fazer com que distâncias maiores sejam importantes para que o avião pare com segurança, antes de a pista acabar. Considere um avião que toca o solo a uma velocidade de 252 km/h e é capaz de desacelerar constantemente, uma vez no chão, a uma taxa de 4,9 m/s². A mínima extensão de pista de que esse avião precisará a partir do ponto de contato com o solo, é de:

Escolha uma opção:
a. 343 m
b. 1 000 m
c. 6 480 m
d. 500 m
e. 1 235 m

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.
