Answer:
<h3>F=2,111.9</h3>
F= two thousand one hundred eleven point nine
Explanation:
Force equals <em><u>Mass(kg)</u></em> times acceleration (M/s^2)
F=<em><u>m</u></em>a
F= <u><em>215.5</em></u> x 9.8
I think they are right! When one of the answers is, all of the above, that is usually the correct answer. pH is important to all living things.
Using Coulomb's Law <span>
F = {k(Q1)(Q2)}/r²
Where F =force in Newtons, k = Coulomb constant, Q1 = - Q2=
charge of the objects in Coulumbs, and r is the distance between the objects.
Solving for r:
r = sqrt[{k(Q1)(Q2)}/F]
where k = 8.897 x 10^9 N•m²/C², Q1 = 2.5 C, Q2 = -2.5 C, and
F = -700 N
Note: Negative magnitude of Force indicates attraction.

If you'll looking for a metal that melts at exactly 1000 degrees celcius, then Red Brass melts at exactly 1000 degrees celcius
1) Equivalent resistance, 1/R = 1/15 + 1/40 + 1/60 = 8+3+2 /120 = 13/120
R = 120/13 = 9.23
2) Current, I = V/R = 115/9.23 = 12.45 A
