Assume distance of seperarion is 1m
F.elec = kQq/r^2
charge of a proton: 1.6×10^-19 C
charge of a neutron: 0 C
F.elec = 0 N
F.grav = GMm/r^2
mass of a proton: 1.672621898×10^-27 kg
mass of a neutron: 1.674927471×10^-27 kg
F.grav = (6.67408×10^-11)×(1.674927471×10^-27)×(1.672621898×10^-27)÷(1^2)
F.grav = 1.8699588×10^-64 N
This is happened because "the air" above "moves faster" and "the pressure" is "lower"
.
Option: 1
<u>Explanation</u>:
Air movement take place from the region where air pressure is more than the region where the pressure is low. When we "blow" air above the "paper strip" paper rises because "low pressure" is created above the strip as high speed winds always travel with reduced air pressure. Hence due to higher air pressure below the strip, it is pushed upwards. This difference in pressure results into fast air moves. This happen because "speed" of the wind depends on "the difference between the pressures" of the air in the two regions.

I believe that the answer to the question provided above is that <span>the most important process in cooling earth’s surface is the production of oxygen by trees , since it has cooling effect and CO2 is reduced.</span>
