Answer:
The answer is C.) 300,000,000 m/s
Explanation:
Light travels at a constant rate of 300,000,000 m/s. this can be determined by dividing the distance (144,000,000,000 meters) by the time (480 seconds). that's pretty fast. in fact, nothing can travel any faster than this. ever.
The correct answer is D. Becquerel showed that uranium gave off radioactivity, and the Curies discovered other radioactive elements.
Explanation:
