The wavelength of the wave is 1.16m and the velocity is 23.64m/s.
To find the answer, we have to know more about the Transverse waves.
<h3>How to find different parameters of a wave?</h3>- The displacement of the string as a function of position and time, y(x,t), when the wave traveling along a string lying along the x-axis is given as,
- Comparing this with the general form of wave equation, we get,
- We have to find the wavelength of the wave, for this, we have the expression as,
- We have to find the velocity of the wave,
Thus, we can conclude that, the wavelength of the wave is 1.16m and the velocity is 23.64m/s

<h2>Answer: Gravity force</h2>
If we approximate the orbit of the planets around the Sun to circular orbits with a uniform circular motion, where the velocity is a vector, whose direction is perpendicular to the radius
of the trajectory; the acceleration
is directed towards the center of the circumference (that's why it's called centripetal acceleration).
Now, according to Newton's 2nd law, the force is directly proportional and in the same direction as the acceleration:
Therefore the net force resulting from the movement of a planet orbiting the Sun points towards the center of the circle, this is called Centripetal Force which is a central force that in this case is equal to the gravity force.
