<h2>
Answer: 540 J</h2>
Explanation:
The Work 
done by a Force 
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
(1)
In this case both (the force and the distance in the path) are parallel (this means they are in the same direction), so the work performed is the product of the force exerted to push the box 
by the distance traveled 
.
Hence:
(2)
I think its Oxygen.
ancient cyanobacteria produced Earth's first oxygen-rich atmosphere, which allowed the eventual rise of eukaryotes. T<span>he chloroplasts of eukaryotic algae and plants are derived from cyanobacteria</span>
Winter
It is winter because the Northern Hemisphere is not facing the sun.
Answer:
4000 kg m/s
Explanation:
<u><em>p=mv</em></u>
- p = momentum in kg m/s
- m = mass in kg
- v = velocity in m/s
substitute values into the formula above to get:
p=1000x4
<u><em>p=4000 kg m/s</em></u>
