Question

Problem 44a

Answer 1

Given information

Given values:

The first distance is km.

 

The second distance is km.

 

Formula used:

 

The square of the distance is inversely proportional to the intensity.

 

 

 

The distance is denoted by the letter .

Then:

 

 

 

The square of the amplitude determines the intensity.

 

 

 

The amplitude is denoted by . Then

 

 

Step-by-step explanation

Step 1.

In many, if not all, disciplines of physics, intensity is an extensively used parameter (and science in general). At its most basic level, intensity is defined as the ratio of a source's power output to the region to which it is applied. Intensities can be used in a variety of ways, including light, earthquakes, and sound, to name a few.
