An ideal Carnot's engine with an efficiency of \(30 \%\) operates between a source and a sink. If the temperature of the source is \(500 \mathrm{~K}\), that of the sink is
- A \(27^{\circ} \mathrm{C}\)
- B \(57^{\circ} \mathrm{C}\)
- C \(77^{\circ} \mathrm{C}\)
- D \(107^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(C) \(77^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
Efficiency of Carnot's engine, \(\eta=30 \%=0.3\) Temperature of source, \(T_1=500 \mathrm{~K}\) Temperature of sink, \(T_2=\) ? We know that, efficiency of Carnot engine,…

- A rough inclined plane \(B C E\) of height \(\left(\frac{25}{6}\right) \mathrm{m}\) is kept on a rectangular wooden block \(A B C D\) of height \(10 \mathrm{~m}\), as shown in the figure. A small block is allowed to slide down from the top \(E\) of the inclined plane. The coefficient of kinetic friction between the block and the inclined plane is \(\frac{1}{8}\) and the angle of inclination of the inclined plane is \(\sin ^{-1}(0.6)\). If the small block finally reaches the ground at a point \(F\), then \(D F\) will be (Acceleration due to gravity, \(g=10 \mathrm{~ms}^{-2}\))
