A skydiver - he uses a parachute that slows him down as a result of air resistance acting on the surface of the parachute
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
Light can travel through undistorted
Sound travels more slowly through a medium when it is at a low temperature because in a low temperature the molecules move slower and in a high temperature the molecules move faster. For Example: ice that is frozen and boiled water in ice the water doesn't move as fast so the molecules were slower than in the boiled water. HOPE I HELPED YOU!!
Spongy materials are the most difficult for sound to travel through. Vacuum is the best acoustic insulation but it doesn't really count for the purpose of this question, since it is not a material but a lack of material.
An hot air balloon i think.
Land tortoises travel slowly but can sometimes manage human walking speeds
Yes it can cause sound waves can travel through solids,liquids,but slowly in gases and air

it traps air inside to slow it down
Sound waves travel most slowly through gases because the particles in gases are more spread out compared to liquids and solids, which hinders the transfer of energy from one particle to another.
Longitudinal (also know as compression) waves travel more slowly through gasses than solids.
No
The outer core is the layer through which P waves travel slowly and S waves cannot travel at all. This is due to the outer core being composed of molten iron and nickel, which hinders the transmission of S waves.
Air.
to allow nutrients to come into contact with the intestinal walls
Sound travels slower through materials that are denser and have a higher elasticity. For example, sound travels more slowly through water, glass, and solids compared to air because the particles are more tightly packed together, causing sound waves to move more slowly through them.
