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.
Impulses travel more slowly through unmyelinated nerve fiber.
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

An hot air balloon i think.
outercore
it traps air inside to slow it down
Longitudinal (also know as compression) waves travel more slowly through gasses than solids.
No
