Answer:
a. f₀ = 6.355 Hz ; b. Δf = 6.35 Hz
Explanation:
Given Data:
Length of wire = l =347 m ;
Tension in wire = T = 65.2 * 10⁶N ;
Linear density = μ = 3.35 kg/m ;
Solution:
a)
Fundamental mode = f₀ = (1/2l)*(sqr.root(T/μ))
By putting the values, we get
f₀ = (1/2(347))*
f₀ = 6.355 Hz
b)
To find the frequency difference between successive modes we need to find frequency of second harmonic first
f₁ = (2/2l)*(sqr.root(T/μ))
f₁ = (2/2(347))*
f₁ = 12.71 Hz
Difference is:
Δf = f₁ - f₀ = 12.71 - 6.355
= 6.35 Hz

The statement 'diverse crops can become vulnerable to pests, disease, and climate change' is considered false regarding this last point (climate change).
<h3>What is adaptation?</h3>
Adaptation is an evolutionary process where a species fits certain environmental conditions.
Plant species are intrinsically vulnerable to climate change because they are adapted to certain climate (temperature) conditions.
In conclusion, the statement 'diverse crops can become vulnerable to pests, disease, and climate change' is considered false regarding this last point (climate change).
