Ques 27 GATE 2023

How many triangles are present in the given figure?

Ques 28 GATE 2023

Students of all the departments of a college who have successfully completed the registration process are eligible to vote in the upcoming college elections. However, by the time the due date for registration was over, it was found that surprisingly none of the students from the Department of Human Sciences had completed the registration process.
Based only on the information provided above, which one of the following sets of statement(s) can be logically inferred with certainty?
(i) All those students who would not be eligible to vote in the college elections would certainly belong to the Department of Human Sciences.
(ii) None of the students from departments other than Human Sciences failed to complete the registration process within the due time.
(iii) All the eligible voters would certainly be students who are not from the Department of Human Sciences.

(i) and (ii)

(i) and (iii)

only (i)

only (iii)

(d) is the correct answer.

Ques 29 GATE 2023

Which one of the following options represents the given graph?

f(x)=x²2^-|x|

f(x)=x2^-|x|

f(x)=|x|2^-x

f(x)=x2^-x

(b) is the correct answer.

Ques 30 GATE 2023

Which one of the options does NOT describe the passage below or follow from it?
'We tend to think of cancer as a 'modern' illness because its metaphors are so modern. It is a disease of overproduction, of sudden growth, a growth that is unstoppable, tipped into the abyss of no control. Modern cell biology encourages us to imagine the cell as a molecular machine. Cancer is that machine unable to quench its initial command (to grow) and thus transform into an indestructible, self-propelled automaton.' [Adapted from The Emperor of All Maladies by Siddhartha Mukherjee]

It is a reflection of why cancer seems so modern to most of us.

It tells us that modern cell biology uses and promotes metaphors of machinery.

Modern cell biology encourages metaphors of machinery, and cancer is often imagined as a machine.

Modern cell biology never uses figurative language, such as metaphors, to describe or explain anything.

(d) is the correct answer.

Ques 35 GATE 2023

The four stator conductors (A, A', B and B') of a rotating machine are carrying DC currents of the same value, the directions of which are shown in the figure (i). The rotor coils a-a' and b-b' are formed by connecting the back ends of conductors 'a' and 'a'' and 'b' and 'b'', respectively, as shown in figure (ii). The e.m.f. induced in coil a-a' and coil b-b' are denoted by E_a-a' and E_b-b', respectively. If the rotor is rotated at uniform angular speed ω rad/s in the clockwise direction then which of the following correctly describes the E_a-a' and E_b-b'?

E_a-a' and E_b-b' have finite magnitudes and are in the same phase.

E_a-a' and E_b-b' have finite magnitudes with E_b-b' leading E_a-a'.

E_a-a' and E_b-b' have finite magnitudes with E_a-a' leading E_b-b'.

E_a-a'=E_b-b'=0

(d) is the correct answer.

Ques 39 GATE 2023

When the winding c-d of the single-phase, 50 Hz, two-winding transformer is supplied from an AC current source of frequency 50 Hz, the rated voltage of 200 V (rms), 50 Hz is obtained at the open-circuited terminals a-b. The cross-sectional area of the core is 5000 mm² and the average core length traversed by the mutual flux is 500 mm. The maximum allowable flux density in the core is B_max=1 Wb/m² and the relative permeability of the core material is 5000. The leakage impedance of the winding a-b and winding c-d at 50 Hz are (5+j100π×0.16) Ω and (11.25+j100π×0.36) Ω, respectively. Considering the magnetizing characteristics to be linear and neglecting core loss, the self-inductance of the winding a-b in millihenry is _______. (Round off to 1 decimal place).

(500.0) is the correct answer.
