- Question
Which is the point from where an azimuth originates?
Options- A. South
- B. North
- C. East
- D. West
- Correct Answer
- North
ExplanationThe azimuth originates at true North i.e, the azimuth originates from the north point. It is a measure of how far an object forms the observer's north point.
Azimuth is a technical mapping term which is used to describe the direction of an angle between north and south on a compass circle through which the circle line passes. It is the most common military method to express direction. When using an azimuth, the point from which the azimuth originates is the center of an imaginary circle.

Correct Answer: 20
Correct Answer: Cylindrical lens
Explanation:
Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea is irregularly shaped or sometimes because of the curvature of the lens inside the eye.
Correct Answer: Velocity
Explanation:
The rate of change of velocity is called as Acceleration.
Correct Answer: fossils
Explanation:
Radiocarbon dating also referred to as carbon dating or carbon-14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
Correct Answer: Argon, copper, silver
Correct Answer: might be accelerated
Correct Answer: 2N
Explanation:
Weight is mass x g. Since mass is constant and g is only of that on the earth. The weight on the moon is only of that on the earth.
Therefore 2N i.e (b) is the answer.
Correct Answer: the red ray
Explanation:
Red is deviated the least and violet the most
Correct Answer: frequency is same but the wavelength is smaller in water than in air
Correct Answer: 4 C
