B) 1950-1959
Sputnik I was launched on October 4, 1957
The potential difference comes out to be

Given:
σ = 8. 85 × 10-9 c/m2
we know,



given the potential difference between two equipotential surface=5v
E=∆v
∆d=∆v/E


Thus the potential difference is

Well, you would reply that that's not what theories are. Theories explain the how and the why, laws explain the what. So, the Big Bang theory isn't "just a theory". It's a theory, it explains the how. (Also, if someone tells you it's anti-God or whatever, tell them the thoery was created by a Catholic scientist. True fact.) I hoped this helped!!! (You don't have the include who created the theory if this is for homework.)
