QUES: In Sri Lanka, the Supreme Court of Sri Lanka was created in 1972 after the adoption of a new Constitution. The Supreme Court is the highest and final superior court of record and is empowered to exercise its powers, subject to the provisions of the Constitution. The court rulings take precedence over all lower Courts. The Sri Lanka judicial system is complex blend of both common-law and civil-law. In some cases such as capital punishment, the decision may be passed on to the President of the Republic for clemency petitions. However, when there is 2/3 majority in the parliament in favour of president (as with present), the supreme court and its judges' powers become nullified as they could be fired from their positions according to the Constitution, if the president wants. Therefore, in such situations, Civil law empowerment vanishes.

What was created in 1927?
What is the answer?

QUES: Some species use vibrations for communicating within members of the same species, such as to attract mates as in the songs of the shield bug Nezara viridula. Vibrations can also be used to communicate between entirely different species; lycaenid (gossamer-winged butterfly) caterpillars which are myrmecophilous (living in a mutualistic association with ants) communicate with ants in this way. The Madagascar hissing cockroach has the ability to press air through its spiracles to make a hissing noise as a sign of aggression; the Death's-head Hawkmoth makes a squeaking noise by forcing air out of their pharynx when agitated, which may also reduce aggressive worker honey bee behavior when the two are in close proximity.

Living in association with ants is called what?
What is the answer?
ANS: myrmecophilous
QUES: DC commutating electric motors, if fitted with laminated pole pieces, become universal motors because they can also operate on AC; reversing the current in both stator and rotor does not reverse the motor. But the now-standard AC distribution frequencies of 50 and 60 Hz caused difficulties with inductive reactance and eddy current losses. Many railways chose low AC frequencies to overcome these problems. They must be converted from utility power by motor-generators or static inverters at the feeding substations or generated at dedicated traction powerstations.

How can DC motor turn universal?
What is the answer?
ANS:
if fitted with laminated pole pieces
