Question

what is order of magnitude of 3600 sec ?​

Answer 1

Answer:

Explanation:

It's fractions of a degree.

24 hours is 360 degrees that sun casts it's rays on Earth.

Or one hour is euqal to 15 degrees the Earth rotates.

You may convert seconds in units of length taking the latitude on which you stand as circumference.circumference of Earth is 40000 km

One hour at equator is equal to 40000/15=2666.66 km

One second at equator = 2666.66/3600= 0.74 km

Or 740 meters

At poles one hour = 15 degrees.

And one second= 15/3600 degrees.= 4*10^-3 degrees.
