CAT (VARC) PYQs

the arrow of time has not yet been tested for atomic clocks.

quantum computers are likely to produce more heat and, hence, more entropy, because of the emphasis on their clocks' accuracy

grandfather clocks are likely to produce less heat and, hence, less entropy, because they are not as accurate.

a clock with a 50-nanometre-thick membrane of silicon nitride has been made to vibrate, producing electric currents.
