The key thing we look for is <u>WATER.</u> We need to analyze whether a world is a possible home to life if it has the past, present, and future existence of liquid water.
Even if the planet has evidence of atmospheric oxygen, it is still insufficient for humans to live in it if it lacks H2O.
Some may argue that the presence of organic molecules such as amino acids should also be taken into account. Even if they have a valid point, it is not the most significant factor that we consider when deciding if the world is a possible home for life.
Aside from water, the world's surface color changes that indicate vegetative growth can be critical in ensuring that the world is habitable. However, vegetative growth is insufficient to be significant if the planet lacks a consistent source of water.
The first confirmed Earth-size planet where liquid water might accumulate on the surface is Kepler-186f. The discovery of another world provides evidence that there are planets in other stars' habitable zones.

Answer:
Explanation:
From the question we are told that:
First Mass
2nd Mass
Distance
Generally the Newtons equation for Gravitational force is mathematically given by
Therefore
Initial force on m
Final force on m
Acceleration of m
The car's rate of acceleration : a = 2.04 m/s²
<h3>Further explanation</h3>
Given
speed = 110 km/hr
time = 15 s
Required
The acceleration
Solution
110 km/hr⇒30.56 m/s
Acceleration is the change in velocity over time
a = Δv : Δt
Input the value :
a = 30.56 m/s : 15 s
a = 2.04 m/s²
Inside the torch, they usually use copper or brass to conduct electricity.
