The main purpose of the turbine in the turbojet engine is to "<span>compress the air". There is also the added factor of pushing the air, which increases mobility. </span>
When a gas is inside the tube, the individual air molecules travel the length of the tube.
<h3>What is molecules?</h3>
The individual particle of a gas element moving randomly inside the element structure.
When the gas contained in a container, the molecules move randomly inside it. According to the kinetic theory of gases, molecules travel the mean distance. The air molecules vibrates horizontally parallel to the length of the tube.
In an open tube, air molecules are distant from each other. So, they can travel the length of the tube.
Thus, individual air molecules travel the length of the tube.

Total resistance = voltage / current = 220 / 5 = 44 ohms .
Even one 176-ohm resistor is too much. The current through it is 1.25 A,
and more than one of them in series reduces the current even further.
Connecting them in <em><u>parallel</u></em>, however . . .
Four resistors of 176-ohms each, in <u>parallel</u>, have a net effective resistance
of 176/4 = 44 ohms ... exactly what you need to do the job.
ΔK = -2334.66J. The kinetic energy loss is -2334.66J.
This is an example of elastic collision which means that the two bodies remain united after the collision, as we know the amount of movement is preserved that is called conservation of momentum. So, we can write the equation as follow:
Where 
is the initial momentum and 
is the final momentum.
Substituting the values:
After the collision the bodies are united and move at the speed of 33.33 m/s.
To calculate the kinetic energy lost in the impact we only have to calculate the energy of each body before the impact and compare it with the energy of the whole after the impact.
