Which variable is directly proportional to frequency?
zhuklara [117]

For this case we have by definition:

v = λf

We observe that we have a linear relationship, where λ is the constant of proportionality.

We have then:

  • <em>v: speed of propagation of the wave </em>
  • <em>λ: wavelength </em>
  • <em>f: frequency </em>

Answer:

The variable that is directly proportional to the frequency is λ, the wavelength.

Ali mixes 20g of Sodium Chloride in 100g of water at 15 Degree °C. Calculate the mass of the solution
Lera25 [3.4K]

Answer:

The mass of the solution is 120 g.

Explanation:

The mass of the solution is given by:

m_{sol} = m_{1} + m_{2}

Where:

m_{sol}: is the mass of the solution

m_{1}: is the mass of the solvent

m_{2}: is the mass of the solute

In the solution, the solvent is the majority compound (in mass) and the solute is the minority (in mass), so the solvent is the water and the solute is sodium chloride.          

Hence, the mass of the solution is:

m_{sol} = m_{1} + m_{2} = 100 g + 20 g = 120 g  

I hope it helps you!
