NC means North Carolina.
Answer:
The temperatures will increase.
Explanation:
What will happen is that the temperature will increase. This is because, in wind direction and weather forecasting, a wind that shifts from the south means that warmer air/temperatures are approaching whereas a wind shift from the north implies that cooler air/temperatures are approaching.
Answer:
173.45 K
Explanation:
This an Adiabatic process because no energy is lost by thermal conduction on expansion. We will be using this Adiabatic condition and ideal gas equation to solve the question.
From idea gas equation;
PV = nRT
-----(1)
where
P is pressure of the gas
V is volume of the gas
n is number of moles
R is gas constant 8.31441 J K-1 mol-1.
T is temperature in Kelvin
For Adiabatic Condition;
----(2)
Substituting equation(1) into equation(2)
Eliminating the constants and simplify with exponent
Making T₂ the subject of the formula;
The temperature when the initial volume has quadrupled ⇒ V₂ = 4V₁
⇒
Since air is diatomic, we assume k = 1.4
∴
T₂ = 173.45 K
Answer:
a. one line down one line to the right one live to the northwest from the object
b. t1=190 t2=310
Explanation:
The answer is the electron microscope. It is a kind of
microscope that uses electrons to light a sample and make an enlarged
image. These kinds of microscopes have much better determining
power than light microscopes and can get much higher magnifications.
Rise in altitude is directly proportional to decrease in pressure
The earth's atmosphere has its own pressure known as atmospheric pressure.The pressure level is highest right at the surface of the earth because the air at this level is supporting the weight of all the air above it. More weight above means a greater downward gravitational force. As we move up through levels of the atmosphere, the air has less air mass above it and gravity isn’t strong enough to pull down a greater number of particles. So the balancing pressure decreases. This is why atmospheric pressure drops as we rise in altitude.
