PLZ DO BOTH PARTS FOR 100 POINTS AND ILL DO ANYTHING!!!!
Kitty [74]

Step-by-step explanation:

<h3>Part A</h3>

<u>Multiply the energy produced in 1 second by the number of seconds:</u>

  • 3.9*10^{33} * 1.55*10^7 = 6.045*10^{40} erg
<h3>Part B</h3>

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.

What is the length of CD ? In this diagram ABC EDC ?<br> Please help !!!!
n200080 [17]
Answer:
CD = x = 4 units

Explanation:
We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:
\frac{BC}{CD} =  \frac{CA}{CE} =  \frac{AB}{ED}

W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5

Substitute in the above proportionality and solve for x as follows:
\frac{20-x}{x} =  \frac{20}{5} = 4

4x = 20 - x
5x = 20
x = 4

Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units

Hope this helps :)
