la longitud de un cable de aluminio es de 30 m a 20 C. Sabiendo que el cable es calentado hasta 60 C y que el coeficiente de dilatacion lineal del aluminio es de 24x 10 -51 C, determina la longitud final del cable y su dilatacion.​

30cm

Explanation:

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
