Answer: The acceleration doubles
===========================================================
Explanation:
Consider a mass of 10 kg, so m = 10
Let's say we apply a net force of 20 newtons, so F = 20
The acceleration 'a' is...
F = ma
20 = 10a
20/10 = a
2 = a
a = 2
The acceleration is 2 m/s^2. Every second, the velocity increases by 10 m/s.
---------------
Now let's double the net force on the object
F = 20 goes to F = 40
m = 10 stays the same
F = ma
40 = 10a
10a = 40
a = 40/10
a = 4
The acceleration has also doubled since earlier it was a = 2, but now it's a = 4.
---------------
In summary, if you double the net force applied to the object, then the acceleration doubles as well.
Acceleration is directly proportional to the net force on an object, and inversely proportional to its mass.
So if an object's mass stays the same while the net force on it doubles, then its acceleration will also double.

The charge of the two objects. The electric force is proporcional to the product of the charges of both objects.
The distance that separetes them. The electric force is proportional to the inverse of the squared distance that separates the objects.
The media. The electric force constant of proportionality depends on the media: air, water, oil, glass.
Answer:c or 3 or the distance between the objects and the amount of charge on the objects

Final answer:
Measuring precipitation is essential for predicting weather and climate trends, understanding impacts of climate change, and monitoring ecosystem health as it affects numerous species' habitats and the global water cycle.
Explanation:
Measuring the amount of precipitation falling worldwide is crucial for scientists for several reasons. Firstly, precipitation patterns heavily influence climate and weather patterns globally. Monitoring these patterns helps in predicting weather and climate trends accurately, which is essential for agricultural and water resource planning. Secondly, significant changes in precipitation patterns can indicate climate change. These changes have potential impacts on sea level, global temperature, and biodiversity. Therefore, understanding them plays an important role in developing strategies for mitigation and adaptation. Lastly, quantifying precipitation is also vital for monitoring the health of ecosystems, as it affects the habitats of numerous species and influences the global water cycle.
