Work = (force) x (distance)
80 J = (force) x (4 m)
Force = (80 J) / (4 m) = 20 N
That's IF the force was in the same direction as the 4m of motion.
If the force was kind of slanted, then it had to be stronger, and
it had a component of 20N in the direction of the motion.
When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.

Answer:
C
Explanation:
The change in momentum of x has to be the opposite of the change in momentum of Y because the momentum is just transferred from one to another. But I'm still trying to figure it out how to calculate.
Answer:
<h2>50 N</h2>
Explanation:
The force required can be found by using the formula
![f = \frac{w}{d} \\](https://tex.z-dn.net/?f=f%20%3D%20%20%5Cfrac%7Bw%7D%7Bd%7D%20%20%5C%5C%20)
w is the workdone
d is the distance
From the question we have
![f = \frac{25}{0.5} \\](https://tex.z-dn.net/?f=f%20%3D%20%20%5Cfrac%7B25%7D%7B0.5%7D%20%20%5C%5C%20)
We have the final answer as
<h3>50 N</h3>
Hope this helps you
