Perpetual motion machine of second kind violates the Correct Answer Kelvin-plank statements

Perpetual motion machine of the second kind (PMM2): A fictitious machine which produces net work in a complete cycle by exchanging heat with only one reservoir is called the PMM2.

It violates the Kelvin plank statement.

If Q2 = 0

i.e. Wnet = Q1

or Efficiency = 100%

The heat engine will produce network in a complete cycle by exchanging heat with only signal reservoir thus violating the Kelvin-Plank statement.

Thus, PMM2 violates the second law of thermodynamics and It is a hypothetical machine.

Thus a perpetual motion machine is a hypothetical machine whose operation would violate the law of thermodynamics.

In a press there are three types of printing machines A, B, and C. Machine A can print ten thousand pages in 8 hours, machine B can do the same task in 10 hours, and machine C can do the same task in 12 hours. All three machines start the task at 9∶00 a.m. Machine A breaks down at 11∶00 a.m. and machines B and C continue working. At 12∶00 noon machine B also breaks down and machine C alone has to complete the remaining task. What is the approximate time of completion of the task?
Suppose we want to design a synchronous circuit that processes a string of 0’s and 1’s. Given a string, it produces another string by replacing the first 1 in any subsequence of consecutive 1’s by a 0. Consider the following example. Input sequence: 00100011000011100 Output sequence: 00000001000001100 A Mealy Machine is a state machine where both the next state and the output are functions of the present state and the current input. The above mentioned circuit can be designed as a two-state Mealy machine. The states in the Mealy machine can be represented using Boolean values 0 and 1. We denote the current state, the next state, the next incoming bit, and the output bit of the Mealy machine by the variables s, t, b and y respectively. Assume the initial state of the Mealy machine is 0. What are the Boolean expressions corresponding to t and y in terms of s and b ?
