Answers:
The transportation industry is no stranger to the manipulation of everyday physics. Cars and trains utilize the wheel, which provides a smooth, steady motion. 
The ears hear sounds which occur through the movement of air molecules, and the chemistry that drives all of biology depends on the physics of energy and molecules. Every day, for example, plants absorb sunlight, water, and carbon dioxide, creating glucose and releasing oxygen as a byproduct.

Explanation:
It is known that wave intensity is the power to area ratio. 
Mathematically,    I = 
As it is given that power is 28.0 W and area is  .
.
Therefore, sound intensity will be calculated as follows.
              I = 
                = 
                 = 
or,             = 
Thus, we can conclude that sound intensity at the position of the microphone is  .

The speed of tsunami is a.0.32 km. 
Steps involved  : 
The equation s = 356d models the maximum speed that a tsunami can move at. It reads as follows: s = 200 km/h d =? 
Let's now change s to s in the equation to determine d: s = 356√d 200 = 356√d √d = 200 ÷ 356 √d = 0.562 Let's square the equation now by squaring both sides: (√d)² = (0.562) ² d = (0.562)² = 0.316 ≈ 0.32 
As a result, 0.32 km is roughly the depth (d) of water for a tsunami moving at 200 km/h.
