Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster does not belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
FUT
To solve this problem, let's first determine the pattern or rule that the letter-clusters are following. We'll check each group of letters to see if they share a common characteristic based on their positions in the English alphabet.
- CEG: The position of the letters C, E, and G in the alphabet are 3, 5, and 7 respectively. Notice that they are separated by a gap of 2 between each successive letter: C (3) + 2 = E (5) + 2 = G (7).
- JLN: The positions are 10, 12, and 14. Similar to CEG, the letters have a gap of 2 between each successive letter: J (10) + 2 = L (12) + 2 = N (14).
- FUT: The positions are 6, 21, and 20. Here, the gap is not consistent. From F to U, the difference is 15, and from U to T, the difference is -1. This breaks the pattern seen in the other groups.
- TVX: The positions are 20, 22, and 24. There is a consistent gap of 2: T (20) + 2 = V (22) + 2 = X (24).
Based on this pattern analysis, the letter-cluster FUT does not belong to the group as it doesn't follow the consistent gap rule of 2 between the letter positions.
Important Questions from Resistance and Resistivity
Which of the following statements are correct about the electrical resistance and resistivity of a wire?
1. Both quantities depend on the area of cross-section of the wire
2. Both depend on the temperature
3. Resistance of the wire is directly proportional to the resistivity of the wire
4. Resistivity of the wire is directly proportional to the length of the
wireSelect the correct answer using the code given below:
A circular coil of single turn has a resistance of 20 Ω. Which one of the following is the correct value for resistance between the ends of any diameter of the coil?
Let us consider a copper wire having radius r and length l. Let its resistance be R. If the radius of another copper wire is 2r and the length is l/2 then the resistance of this wire will be
If the length of a conductor is doubled, then the resistance of the conductor will be: (other parameters are kept same)
Which factor does NOT affect the resistivity of a material?
