Answer:
86400 seconds
Explanation:
To convert a mean solar day to second :
Number of hours in a solar day = 24 hours
Number of minutes per hour = 60 minutes
Number of seconds per minute = 60 minutes
Hence, the number of seconds in a solar day is :
(Number of hours in a solar day * number of minutes in an hour * number of seconds in a minute)
(24 * 60 * 60) seconds = 86400 seconds
Hence, 1 mean solar day = 86400 seconds
