Relative motion can best be defined as B<span> the motion of one object as it appears to another object.
An example is when you are in a car the car has the actual motion because it is the one moving but you are also moving because of relative motion.</span>
Answer:
The answer is "
"
Explanation:
For point a:
Energy balance equation:
From the above equation:
because the rate of air entering the tank that is 
constant.
Since the tank was initially empty and the inlet is constant hence,
Interpolate the enthalpy between 
. The surrounding air
temperature:
Substituting the value from ideal gas:
Follow the ideal gas table.
The 
and between temperature 
Interpolate
Substitute values from the table.
For point b:
Consider the ideal gas equation. therefore, p is pressure, V is the volume, m is mass of gas. 
(M is the molar mass of the gas that is 
and R is gas constant), and T is the temperature.
For point c:
Entropy is given by the following formula:
Based on the situation above the the work done was 400 Joules. <span>Q = FS cos(theta) is the so-called work function. It's important to learn the work physics; you'll see it over and over in science/physics class. Theta is the angle between the force vector F and the distance vector S. In your problem we assume theta = 0, the two vectors were assumed aligned.</span>
2^4/2^7 = 16/128 = 0.125
(1/2)^3= 0.125
1/8= 0.125
a and f are equivalent
Radiation can carry thermal energy.
