The tuning fork has a frequency of 426.7 is found to cause resonance in a closed column of air measuring 0.186 (the diameter of

lidiya [134]

Answer:

The velocity of the tuning fork sound is 317.4648 m/s

Explanation:

The given parameters are;

The frequency of the fork, f = 426.7 Hz

The length of the closed air column, L = 0.186 m

The diameter of the tube, d = 0.15 m

At the fundamental frequency in a closed tube, we have;

λ = 4·L

Where;

λ = The wavelength of the wave

L = The length of the tube

From the equation for the velocity of a wave, we have;

v = f·λ

Where;

v = The velocity of the (sound) wave

f = The frequency of the wave = 426.7 Hz

λ = 4·L = 4 × 0.186 m = 0.744 m

∴ v = 426.7 Hz × 0.744 m = 317.4648 m/s

Therefore, the velocity of the sound produced by the tuning fork, v = 317.4648 m/s

What condition must be met when writing a formula for an ionic compound

babymother [125]

Answer:

The charge of ions must be balance

Explanation:

Ionic compound: It is that compound which consist of positive and negative ions and ions held together by electrostatic force.Electric force is that force which act between two charges.

The compound is neutral because negative ions is equal to positive ions in the ionic compound.

The charge of ions must be balance.It is necessary condition for writing a formula for an ionic compound.

Hence,the charge of ions must be balance is that condition which must be met when writing a formula for an ionic compound.
