Answer:


Explanation:
Given that height of the projectile as a function of time is

here we know that
h = 147 ft
so from above equation


now by solving above quadratic equation we know that


Answer:
AM has longer wavelength
Explanation:
The relation between the wavelength and teh frequency is given by
v = f x λ
Where, f is the frequency and λ be the wavelength.
It shows that the wavelength is inversely proportional to the frequency.
So, higher the frequency, smaller be the wavelength.
So, FM has high frequency than AM, thus, FM has lower wavelength as compared to AM.
