Answer:
C
Step-by-step explanation:
<h2>—Math</h2>
38% = 38/100
= 19/50
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
Answer:
This is late you said it was due 5 min. yet I this was posted 5 hours. No one can help now.
Step-by-step explanation:
Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5
