-Un automóvil lleva una velocidad de 25 km/h a los 6 segundos, su velocidad es de 70km/h. Calcular su aceleración.

2.08 m/s²

Explanation:

Podemos calcular la aceleración usando la fórmula:

a = (V₂-V₁)/(t₂-t₁)

En nuestro caso:

V₂ = 70 km/h

V₁ = 25 km/h

t₂ = 6 s ⇒ 6/3600 = 0.00167 h

t₁ = 0 s ⇒ 0 h

Introducimos los datos y calculamos la aceleración:

a = = 27000 km/h²

Podemos convertir el resultado a m/s²:

27000 km/h² * = 2.08 m/s²

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.
