Answer:
YESS well it is partly nessary but it depends on the situation
Explanation:
Answer:
1.196 m
Explanation:
Given the wave equation :
y= 0.05 cos(5.25x-1775t)
Recall the general traverse wave relation :
y(x, t) = Acos(kx - wt)
A = Amplitude
To Obtian the wavelength ;
We compare the both equations :
Take the value of k ;
kx = 5.25x
k = 5.25
Recall;
k = 2π/λ
5.25 = 2π/λ
5.25λ = 2π
λ = 2π / 5.25
λ = (2 * 3.14) / 5.25 = 1.196 m
I believe the answer is node, but I'm not totally sure.
Answer:
Electrons
Explanation:
Conductors can be charged by electrons, while insulators cannot. Insulators inhibit the flow of electrons; conductors allow free flow of electrons.
