Question Report Error

A 2 kg mass moving at 4 m/s collides elastically with a stationary 2 kg mass. After collision, first mass

A. Stops

B. Moves with 1 m/s

C. Rebounds with 4 m/s

D. Moves with 2 m/s

Answer: Option A

Solution (By JKExamLibrary)

Equal masses elastic collision: velocities swap. Moving mass stops, stationary moves with 4 m/s.

A body of volume 100 cc weighs 80 g in air. It will float in water with

A. 100 cc submerged

B. It will sink

C. 80 cc submerged

D. 20 cc above water

View Answer & Solution Discuss

Correct Answer: Option C

Explanation:
Density = 80/100 = 0.8 g/cc. Water density 1 g/cc. Fraction submerged = 0.8, so 80 cc submerged, 20 cc above. So option B correct.

Question #3 Report Error

The process of a solid changing directly into gas is

A. Evaporation

B. Sublimation

C. Condensation

D. Melting

View Answer & Solution Discuss

Correct Answer: Option B

Explanation:
Sublimation: solid → gas. Example: dry ice (CO₂), camphor. Deposition is reverse (gas → solid). Melting solid → liquid, evaporation liquid → gas.
