N90
N50
N45
N5
Correct answer is C
P = 40 x 10 + 100 x 5
P = 400 + 500 = 900W
Cost = \(\frac{900 \times 10 \times 5}{1000}\)
Cost = N45

4.0Ω
3.0Ω
1.5Ω
1.0Ω
Correct answer is A
r = \(\frac{E}{I} - R\)
r = \(\frac{1.5}{0.3} - 1\)
r = 4\(\Omega\)

1.5x10-11N
1.5x10-12N
1.5x10-13N
1.5x10-14N
Correct answer is D
F = qE
F = 1.5 x 10-19 x 105
F = 1.5 x 10-14N
