Para realizar alguns tipos de trabalho junto ao solo subaquático, o trabalhador fica dentro de câmaras que recebem ar vindo dá superfície através de tubos especiais. por que a água n? o penetra na câmara onde está o trabalhador? qual a propriedade dá matéria que está sendo aplicada nesse caso? justifique sua resposta.

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.

What is the wavelength of a wave with a velocity of 50 m/s and a frequency of 5hz a 250 m b 0.1 m c 10m d 0.01 m

Use the de broglie's wave equation to find the wavelength of an electron moving at 7.3 × 106 m/s. show your work. note: h = plank's constant (6.62607 x 10-34 j s)
