Answer:

La fuerza eléctrica ejercida entre 2 cargas iguales de magnitud 1 C separado en el aire una distancia de 1 km es 9,000 N.

Explanation:

La ley de Coulomb se utiliza para calcular la fuerza eléctrica que actúa entre dos cargas en reposo. Es decir, esta ley permite predecir la fuerza electrostática de atracción o repulsión existente entre dos partículas según su carga eléctrica y la distancia entre ellas.

La fuerza eléctrica con la que dos cargas puntuales son atraídas o repelidas en reposo es directamente proporcional a su producto e inversamente proporcional al cuadrado de la distancia que las separa, expresada como:

F=k*\frac{q1*q2}{d^{2} }

donde:

  • F es la fuerza eléctrica de atracción o repulsión. En el S.I. se mide en Newtons (N).
  • q1 y q2 son lo valores de las dos cargas puntuales. En el S.I. se miden en Culombios (C).
  • d es el valor de la distancia que las separa. En el S.I. se mide en metros (m).
  • k es una constante de proporcionalidad llamada constante de la ley de Coulomb. Depende del medio en el que se encuentren las cargas. En concreto para el vacío k es aproximadamente 9*10⁹ N·m²/C² utilizando unidades en el S.I.

En este caso:

  • q1= 1 C
  • q2= 1 C
  • d= 1 km= 1,000 m

Reemplazando:

F=9*10^{9} \frac{N*m^{2} }{C^{2} } *\frac{1 C* 1 C}{(1,000 m)^{2} }

Resolviendo obtenes:

F= 9,000 N

What is the power output of a pump which can raise 60kg of water height to height of 10m every minute
sattari [20]

Answer:

<h3>Power = Work Done/time</h3>

=> Power = 60×10×10/60

=> Power = 6000/60

=> Power = 100 Watt

Hence the power output of a pump is 100 Watts.

Elliot jumps up and down on a pogo stick. He weighs 600.N, and his pogo stick has a spring with spring constant 1100N/m. What is
tia_tia [17]

From conservation of energy, the height he will reach when he has gravitational potential energy 250J is 0.42 meters approximately

The given weight of Elliot is 600 N

From conservation of energy, the total mechanical energy of Elliot must have been converted to elastic potential energy. Then, the elastic potential energy from the spring was later converted to maximum potential energy P.E of Elliot.

P.E = mgh

where mg = Weight = 600

To find the height Elliot will reach, substitute all necessary parameters into the equation above.

250 = 600h

Make h the subject of the formula

h = 250/600

h = 0.4167 meters

Therefore, the height he will reach when he has gravitational potential energy 250J is 0.42 meters approximately
