Answer:
I think it's C.
Step-by-step explanation:
A. and D. don't make any sense so I assume they're incorrect. B. just seems wrong also by a small margin.
F = kq2 / r2
q = ne
F = k(ne)2 / r2
n = âš(r2F / ke2) = (r/e) âš(F/k)
k = 9 x 109 Nm2/C2
e = 1.6 x 10-19 C
n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
the answer is 15 complete passes
Answer:
A right triangle or right-angled triangle is a triangle in which one angle is a right angle.
<u>Therefore, one of the angles must be 90 degrees to be a right angle triangle.</u>
Substitute (-11) in for x. You will get 2(-11)-19. Then, use the order of operations to get -22-19=
-41.
Hope that helps!
