Question: The least common shape for a galaxy .
Cluster
cluster
Explanation:
There are four main shapes of galaxies: spiral, galaxies are divided into four main groups: spiral, lenticular, elliptical, and irregular, elliptical, and irregular.
The least common shape is cluster
Spiral galaxies- These are the most common. These have arms extending from a bright bulge in spiral shape.
Elliptical galaxy have ellipsoidal shape.
Lenticular galaxies - Intermediate between elliptical and spiral galaxies.
Irregular shape- No well defined shape
Spherical - Nearly spherical galaxies. These are least
cluster- group of galaxies having irregular shape is the least common shape.
Resistencia = 12.5 Ohmios
Explanation:
Dados los siguientes parámetros;
Voltaje = 3.5 Volts
Corriente = 0.28 Amps
Para encontrar el resistencia;
La ley de Ohm establece que a temperatura constante, la corriente que fluye en un circuito eléctrico es directamente proporcional al voltaje aplicado en los dos puntos e inversamente proporcional a la resistencia en el circuito eléctrico.
Matemáticamente, La ley de Ohm viene dada por la fórmula;
Voltaje = corriente * resistencia
Resistencia = voltaje/corriente
Resistencia = 3.5/0.28
Resistencia = 12.5 Ohmios
Por tanto, la resistencia del filamento de una linterna de bolsillo es de 12,5 ohmios.
