a place x situated at 20 degree east longitude while y at 60 degree east which place which place will experience the Sun rise first also find the difference and time of sunrise of two places
Answers
Answer:
Sun will rise after 2hr 40 minutes at 20°East in comparison to 60°East
Explanation:
A place x situated at 20 degree east longitude while y at 60 degree east which place which place will experience the Sun rise first also find the difference and time of sunrise of two places
60° East will experience the sun rise first
From East to west
360° = 24 hours
=> 1 ° = 24/360 hr
=> 1° = 1/15 hr
=> 1° = 4 Minutes
20°East - 60°East
= - 40°East
= 40° West
20°East is 40°West relative to 60°East
so 40 * 4 = 160 minutes = 2hr 40 minutes
Sun will rise after 2hr 40 minutes at 20°East in comparison to 60°East
Answer:
As mother earth turns towards the East, the site with location Y, 60 deg E longitude will experience sunrise earlier than the location X ,20 deg E longitude, the angular distance between the two is 40 degrees (60–20) and earth rotates at a rate of 15 degrees per hour, so 40/15=2.666 hours or 2 hours 40 minutes.
As a matter of fact, the earth rotates toward the east, higher east longitudes experience receipt of light faster following night time.
Therefore, location Y will experience the sunrise first unless it is in a polar point during the year when the sun is constantly above the horizon.
