It's a bit of a trick question, had the same one on my homework. You're given an electric field strength (1*10^5 N/C for mine), a drag force (7.25*10^-11 N) and the critical info is that it's moving with constant velocity(the particle is in equilibrium/not accelerating).
<span>All you need is F=(K*Q1*Q2)/r^2 </span>
<span>Just set F=the drag force and the electric field strength is (K*Q2)/r^2, plugging those values in gives you </span>
<span>(7.25*10^-11 N) = (1*10^5 N/C)*Q1 ---> Q1 = 7.25*10^-16 C </span>
According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.
Answer: I believe the answer is C. Higher Volume.
Explanation: I apologize if I am incorrect.
Answer:
12.5
Explanation:
If the half life is 25 days then in 50 days it will half twice
50/2=25
25/2=12.5
