Sounds waves are longitudinal waves because in longitudinal waves particles of medium vibrate about there mean position while light is electromagnetic waves which do not require a medium.

All waves have an amplitude, wavelength, and frequency.
Amplitude is how far away the wave moves from its resting place. When drawn on a graph, the amplitude is the distance between the upper (crests) and lower (troughs) points and their center on the wave.
Wavelength is the distance two crests or troughs are away from each other.
Frequency is the number of waves produced in a set amount of time. The unit used to measure frequency is Hertz (Hz).
With sound waves, the frequency determines the pitch. The higher the frequency, the higher the pitch, and vice versa. So, a bass drum, which has a low pitch, would have a lower frequency than a mosquito's whine, which is very high pitched.
Light waves are actually electromagnetic waves. Their frequency determines what kind of wave they are, whether it's gamma rays, ultraviolet, x-rays, or something else.

A mass attached to a 50.0 cm long string starts from rest and is rotated 40 times in one minute before reaching a final angular
ch4aika [34]

To solve this problem it is only necessary to apply the kinematic equations of angular motion description, for this purpose we know by definition that,

\theta = \frac{1}{2}\alpha t^2 +\omega_0 t + \theta_0

Where,

\theta = Angular Displacement

\alpha =Angular Acceleration

\omega_0 = Angular velocity

\theta_0 =Initial angular displacement

For this case we have neither angular velocity nor initial angular displacement, then

\theta = \frac{1}{2}\alpha t^2

Re-arrange for \alpha,

\alpha = \frac{2\theta}{t^2}

Replacing our values,

\alpha = \frac{2(40rev*\frac{2\pi rad}{1rev})}{60^2}

\alpha = 0.139rad/s

Therefore the ANgular acceleration of the mass is 0.139rad/s^2

How do mechanical waves to travel from one place to another?​
AnnZ [28]

Answer:

Mechanical waves require a medium in order to transport their energy from one location to another.

Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.

What are two situational examples of unbalanced forces?
polet [3.4K]

An example of a balanced force is two cards leaning against each other and not falling over, or two football players blocking each other but neither overpowering the other. An example of an unbalanced force is two cards leaning on each other then falling over, or two football players blocking each other, then one tackles the other.
