Light is significantly faster than sound so we will not be able to recognize the difference between the light of the lightning bolt falling and the light actually reaching our eyes. So, we can ignore the time for the light flash to reach you.

Explanation:

The speed of sound in air is 331 m/s. This means that in 1 second sound covers a distance of 331 m. Lightning causes thunder. In order to know the distance of the lightning bolt we must measure the time thunder takes to reach our ears. After looking at the lightning bolt we must note down the time before we can hear the thunder. Then we multiply the speed of sound in air with the time and we will obtain the distance.

For example we hear thunder after 10 seconds of the bolt falling. Then we multiply the time with the speed and we get the distance i.e., 331×10=3310 m = 3.31 km.

Answer from: Quest

An atom (ours, not carroll's) consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6 nm. * if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
