<h2>Answer:    8.69 × 10⁻¹ Hz </h2>

<h3>Explanation: </h3>

Frequency = Speed of Light ÷ Wavelength

                    = (2.99 × 10⁸ m/s) ÷ (3.44 × 10⁻⁸ m)  

                    = 8.69 × 10⁻¹ Hz

The frequency of a light of wavelength 34.4 nm is 8.69 × 10⁻¹ Hz.

<u>Notes:</u>

Hz ≡ /s

1 m = 10⁹ nm

When you add the metal the volume increases from 25.0 to 28.9 how would you find the volume of the metal?
Rzqust [24]

3.9L

Explanation:

Initial volume = 25L

Final volume = 28.9L

The initial volume is the volume of the liquid without the metal in originally in the container. It is 25L

After adding the metal, the volume changes to 28.9L

 Final volume = Initial volume + volume of metal

To find the volume of metal make it the subject of the expression;

    Volume of metal = Final volume - initial volume = 28.9  - 25 = 3.9L

The volume of irregular solids are measured by immersing them in water. The change in volume gives their volume.

Sometimes the volume of water displaced is the volume of the solid.
