784 Newton ( mass x gravity = 80 x 9.8)
Answer:
15 miles
Explanation:
my opinion is 15 because 15 is the most reasonable answer
To solve this problem, we will define speed as the amount of distance traveled per unit of time. We will clear the value of time and in parallel we will convert the Units to an international system to facilitate the calculation since we know the speed of light in a vacuum. The speed defined in terms of distance and time would be
The speed of light in a vacuum is and 1ft is equivalent to , so the estimated time would be
We know that 1 second is equivalent to , therefore
Therefore the time is 1.02ns
The answer is C. an electron in an orbit has a fixed energy.
