C. Greenhouse gases contribute to climate change
Explanation:
It is desirable to use an energy source that does not produce greenhouse gases because these gases contributes a whole lot to climate change.
Over the years, studies have shown that the primary use of fossil fuels have significant lead to changes in the climate.
- Greenhouse gases are produced during the combustion of fossil fuels.
- The most important gas produced in this process is the carbon dioxide.
- The greenhouse gases prevents long range radiation from leaving the earth.
- They waves interacts with the gases and warms the earth surface.
- Anomalous concentration of the gases causes more warming of the earth surface.
- This leads to a change in climate.

This question can be easily solved with newton's second law of motion.
F=ma
a=F/m
=8/0.8
=10m/s^2
We have millions of alveoli under our lungs, they diffuse oxygen molecules in our blood, then they get transported to every organ of our body through our Heart
Hope this helps!
<span>g = GMe/Re^2, where Re = Radius of earth (6360km), G = 6.67x10^-11 Nm^2/kg^2, and Me = Mass of earth. On the earth's surface, g = 9.81 m/s^2, so the radius of your orbit is:
R = Re * sqrt (9.81 m/s^2 / 9.00 m/s^2) = 6640km
here, the speed of the satellite is:
v = sqrt(R*9.00m/s^2) = 7730 m/s
the time it would take the satellite to complete one full rotation is:
T = 2*pi*R/v = 5397 s * 1h/3600s = 1.50 h
Hope it help i know it's long and may be confusing but if you have any more questions regarding this topic just hmu! :)</span>
