your answer should be “How does the number of radioactive atoms change over time?”
mark me brainliest
If you decrease the pressure of a fixed amount of gas, its volume will increase.
For a wave:
v = fλ
v is the velocity, f is the frequency, and λ is the wavelength.
Assuming the velocity of the wave doesn't change...
If you increase its frequency, its wavelength will shorten.
