Question

2. Why are air-filled tubes used to prevent swimmers from drowning?

3. How do your clothes get dirty, even when you do not sit or play in dirty places?

4. What would happen if there is no air in the tyres of your bicycle?​

Answer 1

Answer:

2.The inflatable rubber jacket is worn by swimmers because it protects them form drowning as air is much lighter than water and keeps afloat. The jacket with air in it is less denser than water and will float on it. ..

3.dirty clothes can transfer dirt and bacteria into the hair follicle, causing it to clog and become infected." When that happens, it's possible to get "bacne," as well as pimples on your chest and shoulders where clothes rub against your skin all day.

4.Without it, you could roll over a quarter and know if it was heads or tails. Because the tires are the suspension, they support the load (rider and bike) and filter out some shock and vibration. The great thing about tires as suspension is that they are easily adjustable.
