Energy - of whatever kind - is measured in Joules. Power (energy per time unit) is measured in Watts.
You can't use a sundial in the night when its dark but you can tell the time using a sundial in daytime
It should be measured in sec.
the importance of a sundial is for people to tell time.
Time is measured in seconds.
In the International System of Units (SI Units), time is measured in seconds.
He used a portable sundial.
Yes, but it would be difficult, as the markings on a sundial must firstly be measured very accurately (the markings are not evenly spaced) and tend not to show particularly low figures. However, theoretically, it would be possible - just find an accurate enough sundial.
Time - it is measured in seconds.
Watts. A watt is a joule per second.
It is measured in seconds (s).
You can use ANY unit of speed - but the logical unit of speed in this case would be the one you obtain by dividing the specific unit of length by the specific unit of time, so in this case, miles per hour.
