Why is there a maximum vibration of the air molecules at the open end of a resonance tube?
The air molecules can vibrate more freely at the open end of the tube allowing them
to achieve maximum displacement.

Charge in an Electric Field: An electron is projected with an initial velocity v0 = 8.4 × 107 m/s along the y-axis, which is the centerline between a pair of charged plates, as shown in the figure. The plates are 1.0 m long and are separated by 0.10 m. A uniform electric field of magnitude E in the +x-direction is present between the plates. If the magnitude of the acceleration of the electron is measured to be 8.9 × 1015 m/s2, what is the magnitude of the electric field between the plates? (e = 1.6 × 10-19 C, melectron = 9.11 × 10-31 kg)
