The speed of sound is proportional to the (square root) of the stiffness of the material divided by the density.

Sound travels fastest in solids, so it would travel fastest in wood compared to air and water.
Sound travels best in iron because it is a denser material compared to cloth and wood. Denser materials allow sound waves to travel more effectively and with less loss of energy. Water is also a good medium for sound transmission because it is denser than air.
At the mantle-core boundary, there is a change in density and composition of the material. The increase in density and the solid state of the core allow P waves to travel through, with some refraction due to the change in velocity.
Sound waves travel fastest through solids because the particles in a solid are closely packed together, allowing the vibrations to propagate quickly. In comparison, sound waves travel slower through liquids and even slower through gases because the particles in these states of matter are further apart, causing more resistance to the wave motion. Therefore, materials with higher density and stronger intermolecular forces, such as solids, allow sound waves to travel at their maximum speed.
The fastest moving bullet can travel at speeds of around 4,000 feet per second (1,219 meters per second) for certain rifle bullets. These high velocities allow the bullet to cover a mile in less than two seconds.
The density of an object affects how well sound travels through it. Generally, materials with higher density, such as solids, allow sound to travel faster and more efficiently compared to less dense materials like gases. This is because higher density materials have molecules that are closer together, allowing sound waves to propagate more easily.
Seismic waves travel faster through solid rock than through water because solid rocks have higher density and stronger elastic properties, which allow the waves to propagate more efficiently. In contrast, water has lower density and weaker elastic properties, which result in slower wave propagation.

Not for Orthodox Jews, but the other branches of Judaism allow it.
Some freighters do allow for passenger travel. There are specialty travel agencies that accommodate this type of travel.
yes you can, it's not a limitation to travel
