Answer:
3
Step-by-step explanation:
Since we know QR and RS are the same, we can add them together
6 + 6 = 12
Since the whole line is 15 we subtract 12 from 15
15 - 12 = 3
Hey there!
In the equation mentioned,
f represents function.
Hope my answer helps!
A photo of 6 and 8 is scaled down to 1/2 the size
To find this, you multiply both by 1/2 or divide by 2
The new dimensions are 3 by 4
6 divided by 2=3
8 divided by 2=4
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
