I believe the answer is free electrons
I believe the correct answer is A, Wave 1 has a longer wavelength and a higher amplitude than wave 2. Both A and B are transverse wave, therefore, the wavelength is the distance between two successful crest (highest point) or two successful trough (lowest point). In this case, wave 1 has a longer wavelength than wave 2. Amplitude is the maximum displacement of particles in a wave on either side from the equilibrium point. From the diagram wave 1 as a higher amplitude compared to wave 2.
Answer:
Explanation:
Given a mass spring system
At t = 0.1s, the positions is at x=8cm
x(0.1) = 8cm = 0.08m
Spring constant k=16N/m
Mass attached m = 4kg
Amplitude of oscialltion A=10cm = 0.1m
The angular frequency can be calculated using
w = √k/m
Where k is spring constant in N/m
m is mass attached object to the spring in kg
w = √16/4 = √4
w = 2rad/s.
Generally, the equation of a spring is given as
x = ACos(wt+Φ)
Where,
A is amplitude in metre
w is angular frequency in rad/sec
Φ is phase in radian
x(t) = 0.1Cos(2t + Φ)
At t=0.1 x = 0.08
0.08 = 0.1Cos(0.2+Φ)
Cos(0.2+Φ) = 0.08/0.1
Cos(0.2+Φ) = 0.8
0.2+Φ = ArcCos(0.8), note angle in radiant
0.2+Φ = 0.644
Φ = 0.644 — 0.2
Φ = 0.444 rad.
The phase of the SHM is 0.444rad
The answer is E = 0.44 rad

Generally flow of charge at that point is mathematically given as
Where L is length of the cylinder as given the question
The potential difference that is between the cylinders is
Where is the radius
Where E is the electric field that would be experienced at that point which is mathematically represented as
Where is the is the resistivity as given the question
considering the formula for potential difference we have
To get V we integrate both sides
According to Ohm law
Now making R the subject we have
Substituting for V
