Question

PLZ DO BOTH PARTS FOR 100 POINTS AND ILL DO ANYTHING!!!!

Answer 1

Step-by-step explanation:

Part A

Multiply the energy produced in 1 second by the number of seconds:

• $3.9*10^{33} * 1.55*10^7 = 6.045*10^{40}$ erg

Part B

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.

Answer 2

Multiply the energy produced in 1 second by the number of seconds:

Part A

3.9*10^{33} * 1.55*10^7 = 6.045*10^{40}

Part B

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.
