Answer:
Carbon dioxide therefore comes first of all from the combustion of fossil fuels such as coal, oil or even natural gas. It is also generated by the respiration of all living organisms as well as by the fermentation of sugars in beer and winemaking.

Answer:
K.E=3802.5JOULE
HOPE IT IS HELPFUL TO YOU
Answer:
156.24N
Explanation:
From the data above;
Mass = 23g = 0.023kg
V = 88m/s
Kinetic energy = ½mv²
K.e = ½* 0.023 * 88²
K.E = 89.056J
The force required to accelerate the arrow to that speed and energy in 0.57m
Using equation of motion;
V² = U² + 2as
But U =0
V² = 2as
a = v²/2s
a = 88² / (2*0.57)
a = 6792.98m/s²
The force (F) that accelerates the arrow with that velocity = ?
F = M*a
F = 0.023 * 6792.98
F = 156.24N
Answer:
c) The slope is not constant and increases with increasing time.
Explanation:
The equation for the position of this particle (starting from rest is)
![s = at^2/2 = 5t^2/2 = 2.5t^2](https://tex.z-dn.net/?f=s%20%3D%20at%5E2%2F2%20%3D%205t%5E2%2F2%20%3D%202.5t%5E2)
We can take derivative of this with respect to time t to get the equation of slope:
![s' = (2.5t^2)' = 2*2.5t = 5t](https://tex.z-dn.net/?f=s%27%20%3D%20%282.5t%5E2%29%27%20%3D%202%2A2.5t%20%3D%205t)
As time t increase, the slope would increases with time as well.
The moons gravity controls the tides of the Earth, and depending on position, make the tides rise and fall. If the moon did not exist, we would not have tides.
