Final answer:
The effectiveness of satchel charges in destroying a wooden wall depends on various factors, but typically only one charge is required.
Step-by-step explanation:
In physics, the effectiveness of satchel charges in destroying a wooden wall depends on various factors, such as the size and thickness of the wall, the material of the satchel charges, and the distance between the charges and the wall. However, a single satchel charge is typically enough to destroy a wooden wall, as the explosion generates enough energy to break through the structure.
For example, let's consider a wooden wall with a thickness of 10 centimeters. A satchel charge, when detonated, creates a high-pressure wave that exerts a force on the wall, causing it to collapse. This force is typically enough to break through the wooden wall, regardless of its size or distance from the charge.
Therefore, it generally requires only one satchel charge to destroy a wooden wall.
