Answer:
A) After the Space Age ended, many people moved to other states and the economy began to decline.
Explanation:
After the space age ended, businesses slumped, when the space shuttle program ended those made redundant could not be re absorbed due to a lack of follow-on by NASA. The 2008 recession also had impacted businesses in the area. As such many moved to other states, which had the effect of a brain drain.
After Apollo, in the late 70's, there was a similar decline of economic activities as workers were laid off and where finding it hard to sell off their properties as the real estate prices where low.
The charges are the same in absolute value, so the change of potential energy is the same. That means that the change in kinetic energy is also the same. Then:
1 = Ke/Kp = m_e *v_e^2 / m_p * v_p^2, or
v_e/v_p = sqrt( m_p/m_e),
So the speed of the electron will be sqrt( m_p/m_e) times greater than the speed of the proton
