Detailed Explanation:
Concept: Clock hands coincide when the minute hand catches up to the hour hand.
At 2:00, the hour hand is at 60° (2 × 30°/hour). The minute hand moves at 6°/minute, the hour hand at 0.5°/minute.
After t minutes: 6t = 60 + 0.5t → 5.5t = 60 → t = 120/11 = 1010/11 minutes past 2.
Standard electrode potential of three metals A, B and C are respectively 0.5 V, -3 V and -1.2 V. Reducing power of these metals would be
Detailed Explanation:
Reducing power is inversely related to standard electrode potential (E°) — the more negative the E°, the stronger the reducing agent.
Metal B (−3.0 V) has the most negative potential → highest reducing power. Metal C (−1.2 V) is moderately negative → intermediate reducing power. Metal A (+0.5 V) is positive → lowest reducing power. Order: B > C > A.
