A charge of 12c passes through an electroplating apparatus in 2 min, what is the average current? ​
ryzh [129]

Answer:

Explanation:

If I am not wrong

current = charge/time

All you have to take care of is the units should be in the same system

so

current = 12/(2*60)         ---------  2 min = 2*60 sec

current  = 12/120  = 0.1 amp

Una motocicleta viaja con una velocidad constante de 72m/s calcula su velocidad en km/h
Juliette [100K]

Answer:

Entonces la velocidad de la motocicleta es 259.18 \frac{km}{h}

Explanation:

La regla de tres simple es una operación que ayuda a resolver rápidamente problemas de proporcionalidad, teniendo tres valores conocidos y una incógnita.

Dos magnitudes son directamente proporcionales cuando al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida respectivamente por el mismo número. En otras palabras, dos magnitudes son directamente proporcionales si cuando aumenta una magnitud, también lo hace la otra en la misma proporción o cuando disminuye una magnitud, también lo hace la otra en la misma proporción.

Para resolver una regla directa de tres cuando las magnitudes son directamente proporcionales, se debe seguir la siguiente fórmula:

a ⇒ b

c ⇒ x

Entonces x=\frac{c*b}{a}

La regla directa de tres simple es la regla que se aplica en este caso donde hay un cambio de unidades. Para realizar esta conversión de unidades, primero debe saber que 1 m = 0.001 km. Entonces, si 0.001 km es 1 m, ¿cuántos kilómetros son 72 m?

km=\frac{72 m*0.001 km}{1 m}

km=0.072

Entonces:

72\frac{m}{s} =\frac{72 m}{s} =\frac{0.072 km}{s}

Siendo 1 s=0.0002778 h:

72\frac{m}{s} =\frac{72 m}{s} =\frac{0.072 km}{s}=\frac{0.072 km}{0.0002778 h}=259.18 \frac{km}{h}

<u><em>Entonces la velocidad de la motocicleta es </em></u>259.18 \frac{km}{h}<u><em></em></u>
