Answer:
option (c) 14.7 lbs
Explanation:
Data provided in the question:
Area of the column = 1 square inch
Now,
we know Air pressure at the ground surface level from the atmosphere
= 14.7 Psi
also, it can be represented as
14.7 Psi = 14.7 pounds per square inch
Therefore,
Weight of the air weigh within a column that is 1 square inch in area
= Air pressure × Area
= 14.7 pounds per square inch × 1 square inch
= 14.7 pounds i.e 14.7 lbs
Hence,
The answer is option (c) 14.7 lbs
Answer:
Actually the radiation belts are a negative side effect of the earths magnetic field as well as the Suns magnetic field. As cosmic particles collide with particles in the atmosphere they decay into energetic protons while the outer belt is mostly electrons made in geomagnetic storms.
if it didn't exist we could launch more satellites or have larger space stations without the worry of perpetual radiation exposure as for earth there would be no negative consequences to the loss of the energy.
Non-price rationing system is commonly done by queuing (to resolve rationing problems brought by price ceilings) and by coupons (to restore buyer equilibrium). Favored customers who received special treatment from dealers when there is an excess demand, which means: owners giving goods and services to their friends, is another non-price rationing mechanism.
Answer: C.
Air masses that are hot and dry, and are responsible for heatwaves of summer in the western half of the United States.
Explanation: Air masses have fairly uniform temperature and moisture content in the horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the underlying surface properties where they originate.
Air that stands over the Caribbean Sea, for example, becomes a warm, humid maritime tropical air mass, while air that lies in the Arctic regions of northern Canada takes on the cold and dry characteristics of its surroundings and becomes a continental polar air mass.
