.

Answer:
omg i'm so sorry, i hope you get better <3!
Explanation:
Answer:
The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. Speed shows how long it takes for wavelengths to travel.
Answer:
new volume = 30.513L
Explanation:
V1 =17L , P1= 2.3atm , T1=299K , T2=350K , P2 =1.5atm, V2=?
To find the new volume of the gas we will use the combined gas law.
The combined gas law combines Boyle's law, Charles law and Gay-Lussac's law. Its states that the ratio of the product of pressure and volume to temperature is equal to a constant. its expressed mathematically below.




V2 =30.513L
