Explanation:
F net = 2+6-4 ( 2 and 6 N are in same direction so they get added, 4N in opposite direction so it will be subtracted)
F net=4 N

Solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels
- Solar power; however provides much more energy than fossil fuel power
 - Interestingly too, solar power resource can be used without releasing greenhouse gases compared to fossil fuels power
 - Infact, solar energy is the most reliable 
 
<h3>What is renewable energy?</h3>
Renewable energy simply refers to energy that is not depleted when used. An example of such is solar power.
So therefore, solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels
