The action that will directly affect the gravitational force between two objects is increasing the pressure on the objects (option B).

<h3>What is gravitational force?</h3>

Gravitational force is a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass; believed to be mediated by gravitons.

Gravitational force can also be referred to as the force due to gravity of a planet.

The gravitational force between two objects can be affected by the following factors:

  • Increase in pressure
  • Increase in temperature
  • Increase in speed of objects

Therefore, the action that will directly affect the gravitational force between two objects is increasing the pressure on the objects.

Why are both biotic and abiotic features important in ecosystems and biomes?
Sati [7]

Hope this is helpful! Sorry if my answer is choppy.

Explanation:

Biotic and abiotic features are both important in ecosystems because for example, a biotic factor like a plant, relies on an abiotic factors like the rain and the sun. If the rain were non existent, then the plants would no longer be alive causing a chain reaction in the food system. Biotic factors like plants and animals that are non existent can also cause negative effects in biomes and ecosystems.

In which section of the text would you locate information about kings role in the early civil rights movement?
koban [17]

Answer: A. Peaceful protests

Explanation:

You included no text and neither did you reference one but this should be the correct answer.

Martin Luther King Jr. was known for his non-violent style of protests that would ensure that the government would not use any violence that ensues as pretext to shutdown the protest.

In organizing peaceful protests, King made civil rights marches and the movement in general more effective because they would stage longer protests that the government would have little justification for shutting down. It also drew more empathy from people for the movement who listened to the message and not the violence.
