Explanation:
Rubber has no free electrons, high resistivity. Silver best conductor. Copper widely used conductor. Graphite conducts (non-metal). Insulators: glass, plastic, wood.
Explanation:
Inertia is directly proportional to mass. Heavier object harder to accelerate/decelerate. Newton's first law defines inertia. Momentum is mass × velocity, depends on motion.
