Plus one Onam Physics Answer Key 2025

1.

Answer:
(b) Temperature
Explanation: Temperature is a fundamental quantity. The others (velocity, force, and density) are derived quantities.

2.

Answer:
False
Explanation: The stretching of a coil is determined by its Young’s modulus, not shear modulus. Shear modulus relates to the shape deformation due to shear forces.

3.

Answer:
Water
Explanation: Water has the highest specific heat capacity, meaning it requires more heat to raise its temperature by 1°C compared to most substances.

4.

Answer:
The average kinetic energy of a molecule is given by:
E = (3/2) k T

5.

Answer:

Retardation is 3.06 m/s².
