Sound is a kind of longitudinal (and mechmaical too) wave i.e the medium to transfer energy from one point to another though vibrations.


It is produced with the production of vibrations.
Pachacha [2.7K]3 years ago

Sound is the name of the term that describes mechanical waves. These mechanical waves are produced through vibration. Then, it uses particle to particle interaction to pass on the effect of the original vibration. This is where the concept of ‘Sound needs matter to travel ‘ comes into action, because these particles are only present in what they call ‘matter’. The effect of vibration, is then, carried on from one particle to another, to another and so on till it ultimately reaches the receiver.

Hope this helps.

When a wave has λ=3 m and f=15 Hz, what is the speed of the wave?
Tamiku [17]

Wave speed = (wavelength) x (frequency)

Wave speed = (3 m) x (15 Hz)

<em>Wave speed = 45 m/s</em>

a person dives off the edge of aa cliff 33m above the surface of the sea. assuming that air resistance is negligible, how long d
USPshnik [31]

Answer:

The time is t = 2.595 \  s

The speed is v = 25.43 \ m/s

Explanation:

From the question we are told that

    The height of the cliff is  h =  33 \  m

 Generally from kinematic equation we have that

       h  =  ut + \frac{1}{2} gt^2

before the jump the persons initial velocity is  u =  0 m/s

 So

        33   =  0 * t + \frac{1}{2} 9.8 * t^2

=>      t = 2.595 \  s

Generally from kinematic equation

     v= u + gt

=>  v= 0 + 9.8 * 2.595

=>  v = 25.43 \ m/s
