Question 9 2 pts
As an airplane rises through the atmosphere, machines cause the pressure inside the cabin to
decrease. Based on your observations from the Can Crush Lab, why is this change in pressure
necessary? (2 points)
Air pressure inside the plane should match the air pressure outside the plane.
Air pressure inside the plane should be less than the air pressure outside the plane.
Air pressure outside the plane should be less than the air pressure inside the plane.
Air pressure outside the plane should be more than the air pressure inside the plane.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
