7 0

Answer:

Gravitational potential energy = 493,920 J

Explanation:

Given:

Mass of car = 1,200 kg

Height = 42 m

Find:

Gravitational potential energy

Computation:

We know that;

Gravitational acceleration g = 9.8 m/s²

Gravitational potential energy = mgh

Gravitational potential energy = (1,200)(9.8)(42)

Gravitational potential energy = (11,760)(42)

Gravitational potential energy = 493,920 J

CONSIDERAS QUE ES CORRECTO DECIR QUE LOS ANTIBIOTICOS SON MALOS PARA LAS BACTERIAS? Argumenta tu respuesta
vladimir1956 [14]

Answer:

Sí, ya que su función es matarlas o impedir que aumente el número de estas.

Explanation:

Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.

Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.
