Answer:
Option C. 4 Hz
Explanation:
To know the correct answer to the question given above, it is important we know the definition of frequency.
Frequency can simply be defined as the number of complete oscillations or circles made in one second.
Considering the diagram given above, the wave passes through the medium over a period of one second.
Thus, we can obtain the frequency by simply counting the numbers of complete circles made during the period.
From the diagram given above,
The number of circles = 4
Thus,
The frequency is 4 Hz
The tension, T, in each rope is T= mg/2Sinθ
<h3>What is tension force?</h3>
Tension refers to the pulling force in a string which acts in an opposite direction to the force pulling on it.
The tension in each of the ropes are equal since they both make the same angle with the vertical.
Assume the angle the ropes make with the vertical are both θ.
Let the tension in each be T₁ and T₂
Also, T₁ = T₂ = T
T₁Sinθ + T₂Sinθ = mg
2TSinθ = mg
T = mg/2Sinθ
Therefore, the tension, T, in each rope is T = mg/2Sinθ
