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:
y=–8, x=–1
Step-by-step explanation:
I don't have time to explain
Here we have a point and dilation factor and the dilation factor or the scale factor is 12 . SO we need to multiply each coordinate by 12, that is 0 times 12=0 and 4 times 12=48 .
So the image of point after dilation is (0,48) .
