La ley de Ohm y la características de los circuito permite encontrar los resultados para las preguntas de la tabla y los circuitos dados son:

   Parte 1 los valores buscado de corriente, tensión y resistencia son:          

     1) i=2A, 2) i=0,5 A, 3) R=9 Ω, 4) R=9 Ω, 5) V= 60 V, 6) V=22V, 7) R= 221 Ω, 8) i=0,1A, 9) R= 20 Ω y 10) V= 0,050 V

    Parte 2.  Los tipos de circuitos son:

    1)  Serie,  2) Paralelo y  3) Paralelo

    La representación simbólica esta en el adjunto.

La ley de Ohm establece que el voltaje en un circuito es igual a la corriente por la resistencia.

            V= i R

donde V el el voltaje, i la corriente y R la resistencia.

Parte 1

En la tabla adjunta dan una serie de valores calculemos el valor faltante de cada caso

Ejemplo 1.  Indican La resistencia R= 50 Ω, la tensión V= 100V.  Preguntan la corriente

         i= V/R

     

Calculemos  

       i = 100/50

       i = 2 A

Ejemplo 2. Indican la resistencia R= 100 Ω y la tensión V= 50 v. buscamos la corriente.

      i= 50/100

      i= 0,5 A

Ejemplo 3.  Indican la Tensión V= 9 V y la corriente i= 1 A.  Busquemos la resistencia.

      R = V/i

Calculemos

      R = 9/1

      R = 9 Ω

Ejemplo 4. Indican La tensión V= 4,5 V y la corriente i= 0,5 A.  Buscamos la resistencia.

      R = 4,5/0,5

      R=  9 Ω

Ejemplo 5. Indican la resistencia R = 20 Ω y la corriente i = 3 A. Buscamos la tensión.

      V= 3 20

      V= 60 V

Ejemplo 6. Indican la resistencia R = 220 Ω y la corriente i= 0,1 A. buscamos la tensión.

      V= 0,1 220

       V = 22 V

Ejemplo 7. Indican La tensión V= 75,14 V y la corriente i= 0,34 A. Buscamos la resistencia.

       R = V/i

       R = 75,14/0,34

       R = 221 Ω

Ejemplo 8. Indican la resistencia R = 120 ohm y la tensión V= 12 V. Buscamos la corriente.

        I = V/R

        i =12/120

        i = 0,1 A

Ejemplo 9. Indican la tensión V= 40V y la corriente i= 2A. Buscamos la resistencia.

       R = V/i

       R = 40/2

       R = 20 Ω

Ejemplo 10. Indican la resistencia R = 50 ohm y la corriente i= 0,001 A. buscamos la tensión.

        V = i R

         V = 0,001 50

         V = 0,050 V.

Parte 2 Piden identificar el tipo de circuito y representarlo en forma simbólica.

Los circuitos son estructura formadas por fuentes de poder, resistencias, condensadores e inductores por donde circula la corriente, pueden ser de dos tipos:

  • Serie.  Cuando hay una sola linea por  donde circula la corriente.
  • Paralelo. Cuando hay varias lineas o ramas por donde puede circular la corriente.

Circuito 1

Esta formado por dos pilas, una resistencia y dos bombillos, tiene una sola rama, por lo tanto es un circuito tipo: Serie.

En el adjunto tenemos la representacion simbólica.

Circuito 2.

Formado por una pila y tres bombillos, tiene tres ramas por donde puede circular la corriente, por lo tanto es un circuito tipo: Paralelo.

La representacion en el adjunto

Circuito 3.

Formado por dos pilas, una resistencia y dos bombillos, tiene dos ramas donde puede circula la corriente , por lo cual es un circuito tipo: Paralelo.

En conclusión usando la ley de Ohm y la características de los circuito podemos encontrar los resultados para las preguntas de la tabla y los circuitos dados son:

    Parte 1. Los valores buscado de corriente, tensión y resistencia son:          

     1) i=2A, 2) i=0,5 A, 3) R=9 Ω, 4) R=9 Ω, 5) V= 60 V, 6) V=22V, 7) R= 221 Ω, 8) i=0,1A, 9) R= 20 Ω y 10) V= 0,050 V

Suppose you throw a cube-shaped object and a spherical-shaped object of equal volume in the same volume of water. The ball sinks
sergeinik [125]
The objects have different densities
They objects may possess the same volume; however, due to a difference in density, they do not possess the same mass within that volume. This means that they experience a different gravitational force, which causes one to sink and the other to float.

What event triggered the dramatic increase in atmospheric carbon dioxide concentration seen over the last couple of centuries? a
Mice21 [21]

Answer:

a) the Tunguska meteoric impact

Explanation:

The Tunguska Event, sometimes known as the Tungus Meteorite is thought to have resulted from an asteroid or comet entering the earth's atmosphere and exploding. The event released as much energy as fifteen one-megaton atomic bombs. As well as blasting an enormous amount of dust into the atmosphere, felling 60 million trees over an area of more than 2000 square kilometres. Shaidurov suggests that this explosion would have caused "considerable stirring of the high layers of atmosphere and change its structure." Such meteoric disruption was the trigger for the subsequent rise in global temperatures

According to Vladimir Shaidurov of the Russian Academy of Sciences, the apparent rise in average global temperature recorded by scientists over the last hundred years or so could be due to atmospheric changes that are not connected to human emissions of carbon dioxide from the burning of natural gas and oil.

An object with an initial velocity of 27 m/s has a final velocity of 39 m/s after 13 seconds.
grigory [225]

Answer:

<h3>The answer is 0.92 m/s²</h3>

Explanation:

To find the acceleration of an object given it's initial and final velocity and time taken we use the formula

a =  \frac{v - u}{t}  \\

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question

v = 39 m/s

u = 27 m/s

t = 13 s

We have

a =  \frac{39 - 27}{13}  =  \frac{12}{13}  \\  = 0.923076... \:  \:  \:

We have the final answer as

<h3>0.92 m/s²</h3>

Hope this helps you
