forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion. friction: the force that opposes the motion or tendency toward motion of two objects that are in contact.
On an approximate scale, A child breaths 20 times a minute as compared to only 12 to 16 in resting phase of an Adult.
So, In 60 minutes (1 hour), They breathe = 20 * 60 = 1200
In 24 hours (1 day), They breathe = 1200 * 24 = 28,800
In short, Your Answer would be: 28,800
Hope this helps!
The greenhouse effect is a warming effect caused by certain gases that retain heat from sunlight. Without such gases, the average surface temperature of the Earth would be below freezing, and as explained by the Encyclopedia of Environmental Science, “life, as we know it, would not exist.”
<span>
The global warming debate is centered upon whether added greenhouse gases released by human activity will overheat the Earth and cause harmful effects.</span><span>

The answer is if matter is created or destroyed :) Hope this helped you out at least some
Answer:
v / 2
Explanation:
Force F is applied for Δ t time so
impulse = FΔ t
impulse = m( v -u )
= m( v -0 )
= mv
If same force is applied for the same time on mass 2m
FΔ t = 2m v_x
= mv = 2m v_x
v_x = v / 2
