2 answers:
Answer: The amplitude is 15 cm and wavelength is 150 cm.
Explanation:
The wavelength is the distance between two consecutive compression.
The amplitude is the maximum displacement of the wave.
According to the figure,
This wave is longitudinal wave.
So, The amplitude is 15 cm approximate.
Now, the wave length will be
The wavelength is the distance between two consecutive compression is
Hence, The amplitude is 15 cm and wavelength is 150 cm.

Answer:
E1 = 10.15 * 10^4 N/C
E2 = 0
E3 = 10.15 *10^4 N/C
Explanation:
Given data:
Two 13 cm-long thin glass rods ( L ) = 0.13 m
charge (Q) = +11nC
distance between thin glass rods = 4 cm .
<u>Calculate the electric field strengths </u>
electric charge due to a single glass rod in the question ( E ) =
equation 1 can be used to determine E1, E2 and E3 because the points lie within the two rods hence the net electric field produced will be equal to the difference in electric fields produced
applying equation 1 to determine E1
E1 =
( distance from 1 rod is 0.01 m and from the other rod is 0.03 )
=
= 10.15 * 10^4 N/C
applying equation 1 to determine E2
E2 =
therefore E2 = 0
E1 = E3
hence E3 = 10.15*10^4 N/C
