A substance sample has a Mass of 45.0 g, and the Data Safety
marishachu [46]

The volume of the sample is 48.39 cm³.

<h3 /><h3>What is volume?</h3>

The term volume refers to the amount of three-dimensional space taken up by an item or a closed surface

To calculate the volume of the sample, we use the formula below

Formula:

  • D = m/v
  • v = m/D................ Equation 1

Where:

  • m = Mass of the smaple
  • D = Density of the sample
  • v = Volume of the sample.

From the question,

Given:

  • m = 45 g
  • D = 0.93 g/cm³

Substitute these values into equation 1

  • v = 45/0.93
  • v = 48.39 cm³

Hence, the volume of the sample is 48.39 cm³.

If you increase the frequency of a sound wave four times, what will happen to its speed?
ozzi

The speed will increase four (4) times when the frequency of sound wave is increased four (4) times.

<h3>How to calculate the frequency of a wave.</h3>

Mathematically, the frequency of a sound wave is given by this formula:

F = \frac{V}{\lambda}

<u>Where:</u>

  • F is the frequency of a sound wave.
  • V is the velocity of a sound wave.
  • \lambda is the wavelength of a sound wave.

<u>Note:</u> The frequency of the sound wave is increased four (4) times.

  • F = 4F

Substituting the given parameters into the formula, we have;

4F = \frac{V}{\lambda}\\\\V=4F\lambda

Therefore, the speed will increase four (4) times when the frequency of sound wave is increased four (4) times.
