Answer:

Copernicus' heliocentric model

Explanation:

Nicolaus Copernicus was the first one to give the heliocentric model of the solar system. The heliocentric model of the solar system describes the sun to be at the center of the solar system and earth and other planets with their moons revolving about it in concentric orbits.

Kepler believed in Copernicus's heliocentric model but gave laws of planetary motion that described the orbit of the planets to be elliptical instead of circular.

Tycho Brahe view of the solar system was that sun revolved around earth but other planets revolved around the sun.

Ptolemy's geocentric model considered earth to be the center of the universe and sun and other planets revolving about it.

un conductor de plata (p=1,6x10°-6ohm x m) tiene una seccion de 5x10°-6 m°2 y una longitud de 110 m . calcular la resistencia
Alexus [3.1K]

Responder:

35,2 ohm.

Explicación:

Dado:

La resistencia específica del conductor es,

La longitud del conductor es,

El área de la sección transversal del conductor es,

Sabemos que la resistencia de un conductor es directamente proporcional a su longitud e inversamente proporcional al área de la sección transversal.

Por lo tanto, la resistencia se puede expresar como:

R=\frac{\rho\times l}{A}

Ahora, conecte los valores dados y resuelva para 'R'. Esto da,

R=\frac{1.6\times 10^{-6}\ ohm\cdot m\times 110\ m}{5\times 10^{-6}\ m^2}\\\\R=35.2\ ohm

Por lo tanto, la resistencia del conductor es de 35,2 ohm.
