Study the given information carefully and answer the question given below: Shikhar walked 18 km towards east, took right turn and walked 20 km. He then took a left turn and walked 25 km. Then, he took a left turn walked 20 km. Then, he took a right turn and walked 10 km. then, he took a left turn and walked 24 km. Finally he took a left turn and walked 35 km. How far was he from the starting point?

A

22 km

B

25 km

C

28 km

D

30 km

Consider the following statements: 1. A kinematic chain is the combination of kinematic pairs joined in such a way that the relative motion between them is completely constrained. 2. The degree of freedom of a kinematic pair is given by the number of independent coordinates required to completely specify the relative movement. Which of the above statements is/are correct?

A

1 only

B

2 only

C

Both 1 and 2

D

Neither 1 nor 2

Statement I: In four-bar chain, whenever all four links are used, with each of them forming a turning pair, there will be continuous relative motion between the two links of different lengths. Statement II: For a four-bar mechanism, the sum of the shortest and longest link lengths is not greater than the sum of remaining two links.

A

Both Statement I and Statement II are individually true, and Statement II is the correct explanation of Statement I

B

Both Statement I and Statement II are individually true, but Statement II is not the correct explanation of Statement I

C

Statement I is true, but Statement II is false

D

Statement I is false, but Statement II is true

Consider the following two-process synchronization solution. Process 0 - - - - - - - - Entry: loop while (turn == 1); (critical section) Exit: turn = 1; Process 1 - - - - - - - - Entry: loop while (turn == 0); (critical section) Exit: turn = 0; The shared variable turn is initialized to zero. Which one of the following is TRUE?

A

This is a correct two-process synchronization solution.

B

This solution violates mutual exclusion requirement.

C

This solution violates progress requirement.

D

This solution violates bounded wait requirement.
