Sergeu [11.5K]

Answer:

here as we increase the distance the intensity will decrease and hence the amplitude of the electric field will decrease and vice-versa

Explanation:

As wee know that the amplitude of the wave will decide the energy of the wave

Here we know that energy density of electromagnetic wave is given as

$u = \frac{1}{2}\epsilon_0E_0^2$

now we have

$\frac{I}{c} = \frac{1}{2}\epsilon_0 E_0^2$

so here we can say that intensity of the wave at the given distance from the source is given by formula

$I = \frac{P}{4\pi r^2}$

so here as we increase the distance the intensity will decrease and hence the amplitude of the electric field will decrease and vice-versa.

As the shock waves travel in concentric outward circles from the epicenter, and the diameter is measured 120 miles,
area of a circle =πr*r

d=120
r=120/2r=6060*60=36003600*π=11309.734
11309.734 square miles
