Since the equation for density is d=m/v, you can multiply both sides by m in order to get m by itself {d(v)=m}. Plug the volume and density in (1.1x7.9) and you will get 8.69. If you are using proper sig figs, then it will be 8.7g.

Answer:
The shortest wavelength of an AM radio signal is 250 m
The longest wavelength of an AM radio signal is 468.75 m
Explanation:
where,
= Frequency of wave =
c = speed of light =
= wavelength
As we can see that frequency and wavelength are inversely proportional to each other. So wave with high frequency will have shorter wavelength and wave with lower frequency will have longer wavelength.
a) The shortest wavelength of an AM radio signal:
b) The longest wavelength of an AM radio signal:
