खालील विधानांचे परीक्षण करा आणि योग्य पर्याय निवडा : विधान (A) : पृथ्वीच्या परिचलनामुळे प्रत्येक रेखाप्तावर स्थानिक वेळ भिन्न-भिन्न असते. विधान (B) : स्थानिक वेळेतील विसंगती दूर करण्यासाठी प्रमाणवेळ पद्धतीचा वापर केला जातो. Examine the following statements and select the proper options : Statement (A) : Every longitude has a different local time due to the rotation of the Earth. Statement (B) : Standard time system is utilized to remove the difference in the local time.
(a)पृथ्वीच्या परिवलनामुळे प्रत्येक रेखावृत्तावर स्थानिक वेळ भिन्न-भिन्न असते. / Every longitude has a different local time due to the rotation of the Earth.
(b)स्थानिक वेळेतील विसंगती दूर करण्यासाठी प्रमाणवेळ पद्धतीचा वापर केला जातो. / Standard time system is utilized to remove the difference in the local time.
The Earth's rotation causes different longitudes to experience different local times. Standard time systems are implemented to maintain uniformity across a country and eliminate discrepancies.
जर भारतामध्ये प्रमाण वेळ दुपारचे बारा अशी असेल, तर त्याचवेळी अनुक्रमे ग्रिनीच व आंतरराष्ट्रीय बार रेषा या रेखावृत्तावर वेळ काय असेल? If the time in India is 12:00 Noon, what would be the time simultaneously at the Greenwich meridian and the International date line, respectively?
(a)सकाळ 6:30 व सायंकाळ 6:30
(b)सायंकाळ 6:30 व सकाळ 6:30
(c)सकाळ 6:30 व सायंकाळ 5:30
(d)सायंकाळ 6:30 व सकाळ 5:30
India's standard time is GMT+5:30. When it is 12:00 Noon in India, Greenwich (GMT) is 5.5 hours behind, making it 6:30 AM. The International Date Line is 12 hours ahead of GMT, making it 6:30 PM.
