Most experts feel that in spite of possessing all the technical skills required to be a batsman of the highest order, he is unlikely to be so due to lack of requisite temperament. he was guilty of throwing away his wicket several times after working hard to lay a strong foundation. His critics pointed out that until he addressed this problem, success at the highest level will contiunue to elude him. 

Which of the statements(s) below is/are logically valid and can be inferred from the above passage?

i. He was already a successful batsman at the highest level.

ii. He has to improve his temperament in order to became a great batsman.

iii. he failed to make many of his good starts count. 

iv. Improving his technical skills will gurantee success.

In an unconsolidated undrained triaxial test, it is observed that an increase in cell pressure from 150 kPa to 250 kPa leads to a pore pressure increase of 80 kPa. It is further observed that, an increase of 50 kPa in deviatoric stress results in an increase of 25 kPa in the pore pressure. The value of Skempton’s pore pressure parameter B is:

In a two-dimensional steady flow field, in a certain region of the x-y plane, the velocity component in the x-direction is given by v_x = x² and the density varies as ρ = 1/x . Which of the following is a valid expression for the velocity component in the y-direction, v_y?

A circular pipe has a diameter of 1 m, bed slope of 1 in 1000, and Manning’s roughness coefficient equal to 0.01. It may be treated as an open channel flow when it is flowing just full, i.e., the water level just touches the crest. The discharge in this condition is denoted by Q_full. Similarly, the discharge when the pipe is flowing half-full, i.e., with a flow depth of 0.5 m, is denoted by Q_half. The ratio Q_full / Q_half is:
