(3) The amount of energy a sound wave transmits is directly related to the wave's amplitude.
We can even tell this physically because the larger the amplitude, the louder sound is.
Answer:
66.42 N
Explanation:
Torque is defined as the product of force and the perpendicular distance.
Where, r be the distance, f be the force and θ be the angle between the force vector and the distance vector
Case I :
F = 53 N, r = 28 cm = 0.28 m, θ = 90°
So,
case II :
F = ?, r = 0.28 m, θ = 53°
Let the force be F for the same toque.
F = 66.42 N
Thus, the force required is 66.42 N.
I think the correct answer from the choices listed above is option A. Wave motion is a movement of energy through space or a medium . Some waves are visible light waves, heat waves, sound waves and the like. Hope this answers the question.
It is the last number minus 3
