A.
uniform and parallel to the axis of the solenoid
-
B.
inversely proportional to the current
-
C.
zero
-
D.
stronger near the edges
Correct Answer:
A. uniform and parallel to the axis of the solenoid
Explanation:
The logic follows a pattern of shifting each letter backward in the English alphabet by a specific number of positions.
In the first pair, SKIB becomes OGNG: - S moves back 4 places to O
- K moves back 4 places to G
- I moves back 5 places to D (The example OGNG suggests a pattern: S-4=O, K-4=G, I-5=D, B+5=G. However, looking at the second pair CUCV to YQHA: C-4=Y, U-4=Q, C-5=X, V+5=A).Applying the consistent shift of -4, -4, -5, +5 to QIRK: - Q minus 4 positions is M
- I minus 4 positions is E
- R minus 5 positions is M (Wait, checking logic again: Q-4=M, I-4=E, R-5=M, K+5=P).
- Following the -4, -4, -5, +5 pattern:
Q (17) - 4 = M (13)
I (9) - 4 = E (5)
R (18) - 5 = M (13)
K (11) + 5 = P (16)Therefore, QIRK relates to MEMP. However, looking at the provided options (MWEP, MWPE, MEPW, MEWP), the shift for the third and fourth letters in the examples actually follows:
SKIB to OGNG: S(-4)=O, K(-4)=G, I(+5)=N, B(+5)=G
CUCV to YQHA: C(-4)=Y, U(-4)=Q, C(+5)=H, V(+5)=A
Applying -4, -4, +5, +5 to QIRK: - Q (17) - 4 = M (13)
- I (9) - 4 = E (5)
- R (18) + 5 = W (23)
- K (11) + 5 = P (16)The resulting code is MEWP.
