1. According to the laws of transformer
V(in) I (in)= V (out)I (out)
Since V(in)= 120V, I (in)= 0.5A
V(out)= 12V
thus: I(out)= V(in) I (in)/V (out)= 5A
2.
a. N1/N2= 130000/ 10000= 13
b. I( IN)= P/ V(IN)= 1000A
c. P(RESISTENT HE

1.
fm(Cu)= M/NA=64/6.02e-23=1.063e-22
Therefore, the copper atomic is about 1.063e-22g.
Number of Cu is
39/ 1.063e-22=2.833e+22=2.833* 10^22
Electrons= 29*2.821 * 10^22= 8.183* 10^23
Therefore, A penny in
