What is the magnetic declination at a place if the magnetic bearing of the sun at noon is 184°
Answers
Answer: 4° towards West
Explanation:
The angle between true North and magnetic North on the horizontal plane is known as Magnetic Declination. This angle varies from place to place and time.
It is given that the Magnetic Bearing of Sun at Noon at a place is 184°
The magnetic declination is given by the formula
TRUE BEARING - MAGNETIC BEARING = MAGNETIC DECLINATION
The true bearing of Sun at noon is 0° or 180°
Substituting the values:
Magnetic declination =180°-184°=-4°
The negative sign shows that it is towards West.
Answer:
declination = 4*W
Explanation:
At noon means 12 PM. the sun is exactly at the poles or you must be knowing its actually overhead. Since in question it says in Southern hemisphere, therefore it lies exactly at south pole ( True south), thus true bearing of sun becomes 180 degree and since magnetic bearing given as 184 degree. it being more implies that magnetic north will lie to the west of true north(so that this declination gets added to the true bearing to form the magnetic bearing of 184 degrees).
thus declination = (magnetic bearing - true bearing) = 4*W
