It Travels a few centimeters in air as the have weak energy.

It depends upon the size of the fragments. Very small fragments can be blown into the air and carried by air currents around the world.
Surprisingly no. Air is a gas which means that the molecules are far apart. Even a liquid is better that air for sound to travel through because the molecules are closer together. But, a solid is the best for a sound to travel through. This is because the molecules are very close together so the vibration is transferred much quicker though the material.
That depends on the energy of the beta particles and the medium they are passing through. In air beta can travel several inches to several feet. Beta cannot pass through a single layer of aluminum foil.
because alfa particle have a tendency to move in air then beta particles

Discounts on air travel vary as far as the company that offers them, Often times companies will have special deals mainly after holiday times to offer a certain percent off travel tickets. As far as general price goes it will depend on how far one will travel, the amount of luggage or weight of luggage, and how many passengers will travel to name a few examples.
A average hot air balloon can travel around 25 miles. But it all depends on how big it is and how much gas you have
