Answer:
5.09 Pa
Explanation:
Area of the circle = πr²
The diameter is given, so 100/2 = 50 m is the radius.
π x 50² = 7854 m²
Pressure = force/area
Pressure = 40000/7854
Pressure = 5.09 Pa
Hope this helps!

The sound waves pass through the door and will then go further from the space near the door making the sound hear outside the door also.
<u>Explanation:</u>
Waves can twist around corners in view of an impact called diffraction. The sum that a wave will twist around a corner as a result of diffraction is about equivalent to its frequency. So it is a lot simpler to see the bowing of the sound waves, since it is around a million times greater than the bowing of the light waves.
As the waves pass through the door, they bend and travel into the space near the door. Because they spread out into the space beyond the door, a person near the doorway can hear sounds from inside the room.
