According to Einstein's Theory of Relativity, an object at rest experiences the time differently from an object moving: a moving clock would be slower than a resting clock.
Two objects experiencing the same acceleration, do experience the same time dilation, therefore a person on Earth's surface experiencing a gravitational acceleration of 9.8m/s² will feel the same effects of a person on a spaceship accelerating at 9.8m/s².
Hence, the correct answer is: <span>D) Acceleration in space and gravity on Earth have the same effects on objects.

Explanation:
Metals are by far better conductors of electricity than most solids because individual atoms in a metal form a matrix which their outer electrons can move freely. These atoms form a "sea" of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
Solids are usually rigid substances with their atoms in a fixed place unable to move freely.
