MCQ
Equivalent resistance between $A$ and $B$ will be ............ $ohm$
  • A
    $2$
  • B
    $18$
  • C
    $6$
  • $3.6$

Answer

Correct option: D.
$3.6$
d
The circuit reduces to

${R_{AB}} = \frac{{9 \times 6}}{{9 + 6}} = \frac{{9 \times 6}}{{15}} = \frac{{18}}{5} = 3.6\, \Omega $

A cylinder made of perfectly non conducting material closed at both ends is divided into two equal parts by a heat proof piston. Both parts of the cylinder contain the same masses of a gas at a temperature $t_0 = 27^o$ and pressure $P_0 = 1$ atm. Now if the gas in one of the parts is slowly heated to $t = 57^oC$ while the temperature of first part is maintained at $t_0$ the distance moved by the piston from the middle of the cylinder will be.... $cm$ (length of the cylinder $= 84\,\, cm$)
