Answer to Question 1

Light travels at 300,000 km/sec, so the flash of light is almost instantaneous from a few miles away; sound travels at about a fifth of a mile per second, so if the thunder follows the lightning by five seconds, the bolt hit about a mile away.

Answer to Question 2

As with the making of our Moon and Earth's axial tilt, a large impact is possibly the factor that flipped Uranus over on its side.
