Answer:
Substance 1 because it became a liquid faster
Explanation:
Answer:
The value is
Explanation:
From the question we are told that
The length of the string is
The mass is 
The frequency produced at fourth harmonic vibration(i.e n =4 ) is 
Generally the wavelength of the string is mathematically represented as

=>
=>
Answer:
Surface
Explanation:
Rayleigh Waves—surface waves that move in an elliptical motion, producing both a vertical and horizontal component of motion in the direction of wave propagation. Particle motion consists of elliptical motions (generally retrograde elliptical) in the vertical plane and parallel to the direction of propagation.
initial velocity is given as 41 km/h at 60 degree North of West


After some time the velocity is given as

now we can find the acceleration



now the distance is given by




so the magnitude of distance is
