A fraction of a second
occurs in the tropopause- environmental lapse rate or normal elapse rate ELR
2.16 meters is halfway between.
The difference between 50 meters and 5 meters is 50 meters - 5 meters, which equals 45 meters.
Light travels at about 343 meters per second in air. With a 2-second delay, the lightning strike would be approximately 686 meters away from you.
Directly between 15 meters and 17 meters would be 16 meters. Though there are MANY numbers that may be between them. For example, 15.679, 16.00039, 16.09873522, etc.
The time lag between seeing the flash of lightning and hearing the thunder corresponds to the distance between you and the lightning strike. To calculate this distance, you can use the fact that sound travels at approximately 343 meters per second in air. So, for a 4-second time lag, the lightning strike is approximately 1372 meters away.
You can't convert between meters and square meters.
None.
8.5 meters is half way between 8 metres and 9 meters. 8.25 meters is a quarter of the way from 8 meters to 9 meters. Other measurements that are between 8 and 9 meters are 8.1, 8 3/4, 8.0000028. etc. 8 meters is about 26.2 feet. 9 meters is about 29.52 feet. So anything between 26.2 feet and 29.53 feet is also likely within 8 and 9 meters.
8.5 meters or 8 1/2 meters
meters are bigger
Square meters measure area but linear meters measure distance.
