The answer is true about the cabins in commercial airliners that require pressurization.
<h3>Why are the cabins of commercial airplanes pressurized?</h3>
Airplanes are pressurized because the air is very thin at the high altitude where they fly. The passenger jet has a cruising altitude of about 30,000 - 40,000 feet. At this altitude or height, humans can't breathe very well and our body gets less amount of oxygen. Most aircraft cabins are pressurized to an altitude about 8,000 feet. This is called cabin altitude. Aircraft pilots have access to the control's mode of a cabin pressure control system and if needed it can command the cabin to depressurize.
So we can conclude that cabins in commercial airliners require pressurization because of the greater pressure of the surrounding environment.

Answer:
I can't do the sketch
the direction of elections would move though the wires opposite direction
the 3rd one I'm not sure
The circuit shown has a battery and two resistors, with R1>R2. Which of the two resistors dissipates the larger amount of power? Explain
Rank in order, from largest to smallest, the three currents I1 TO I3. And explain why?
The two batteries are identical and the four resistors all ahve exactly the same resistance.
a) Compare change in V(ab), V(cd), and V(ef). Are they all the same? In not, rank them in decreasing order. Explain you reasoning
b) Rank in order, from largest to smallest, the five currents I1 to I5, and ezplain why
The measurements used in the experiment is the amount of speed over time.
The measurement of speed is indicated along the “y” axis.
Upon viewing the graph, the highest point along the “y” axis shown is 25 m/s. This would be the maximum.
The maximum speed of the car would be 25 m/s.
