d) entire universe is governed by a single set of fundamental physical laws.
Explanation:
Astronomy is the field of study that researches and studies about the objects beyond Earth. The phenomena occurring in the universe and their effects on the planet Earth are all death under the subject of astronomy. The discovery and the origin of the Earth, the heavenly bodies and their existence are covered under astronomy. The fundamental laws of the astronomy proves to be equivalent for all the bodies. These laws are universal that helps in the research of the science of universe.
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v choice: D
