Answer:
the <u>Fundamental Frequency</u> of vibration of a wave is defined as that which has the lowest frequency
Explanation:
As we know that the frequency of vibrations on a string is given as
now we know that
N = number of harmonics
v = speed of the wave
L = length of the string
So here for the lowest frequency of the wave we know that
N = 1
so lowest frequency of the wave is known as fundamental frequency of the wave
the <u>Fundamental Frequency</u> of vibration of a wave is defined as that which has the lowest frequency

Explanation:
Forces are 100 pound and 150 pound and angles with x axis are 20°and 60°.
That is force 1 is 100 pound with x axis at 20°
F₁ = 100 cos 20 i + 100 sin 20 j
F₁ = 93.97 i + 34.20 j
That is force 2 is 150 pound with x axis at 60°
F₂ = 150 cos 60 i + 150 sin 60 j
F₂ = 75 i + 129.90 j
F₁ + F₂ = 93.97 i + 34.20 j + 75 i + 129.90 j
F₁ + F₂ = 168.97 i + 164.10 j
Resultant is 235.54 pounds at an angle 44.16° to X axis.
