Step-by-step explanation:
<h3>Part A</h3><u>Multiply the energy produced in 1 second by the number of seconds:</u>
erg
10⁻³ is same as 0.001 times and 10³ is same as 1000 times.
1.6*1000 = 1600 mm = 160 cm = 1.6 m is way too big for the measurement of the distance between the tracks on a CD.
So the first option is correct.
