  3. C.Element with 20 protons and 19 neutrons
  4. D.Element with 18 protons and 22 neutrons
Show answer
Correct answer: D. Element with 18 protons and 22 neutrons

Isobars are atoms of different elements with the same mass number, and 18 + 22 gives a mass number of 40, the same as calcium.

Q1580.General ScienceAsked in: CDS · CDS-II 2018, GKMedium

The direction of magnetic field at any location on the earth's surface is commonly specified in terms of

  1. A.field declination
  2. B.field inclination
  3. C.both field declination and field inclination
  4. D.horizontal component of the field
Show answer
Correct answer: C. both field declination and field inclination

A direction in space needs two angles, one in the horizontal plane and one in the vertical plane, and declination and inclination supply exactly these.
