- d) Linear Momentum
Answer:
10. In the solar system, which is conserved:
a) Total Energy
b) K.E.
c) Angular Velocity
d) Linear Momentum
Answer: a) Total Energy
Explanation: In the solar system, total energy (the sum of kinetic and potential energy) is conserved in the absence of external forces. According to the law of conservation of energy, the total energy of a closed system remains constant over time. While individual components (kinetic and potential energies) can change, the total energy remains constant unless affected by an external force.
