2.it is mathematically impossible for humans to fly like birds. A bird can fly because its wingspan and the wing muscle strength are in balance with its body size. ... Thus, an average adult male human would need a wingspan of at least 6.7 meters to fly.

3.When your car needs fuel, you “feed" it gasoline. Just like your body converts food into energy, a car engine converts gas into motion. ... The explosions force pistons in the engine to move. When the energy from the first explosion has almost run out, another explosion
