The sun produces 3.9 ⋅ 10 to the 33th power ergs of radiant energy per second. How many ergs of radiant energy does the sun prod
arlik [135]
So the sun produces 3.9x10³³/ second

Using this ratio (3.9x10³³/ second) we can use the porpotions to calculate time taken (T) to produce 1.55x10⁷.

\frac{3.9(10^3) ergs}{1 second} =  \frac{1.55(10^7)ergs}{T}

Then isolate T and find the time

\frac{T3.9(10^3)ergs}{1 second} = {1.55(10^7)ergs
T3.9(10^3)ergs = ({1.55(10^7)ergs)seconds
T =  \frac{(1.55(10^7)ergs)seconds}{3.9(10^3)ergs}
T =  \frac{(1.55(10^7)seconds}{3.9(10^3)}
T = \frac{1.55}{3.9}(10^4)seconds
T = 0.397(10^4)seconds
T = 3.97(10^-^1)(10^4)seconds
T = 3.97(10^3)seconds

Thus it took 3.97x10³ seconds for 1.55x10⁷. of ergs to be produced
Hope that helped and if it did, a Brainliest rating would be much appreciated

(-7)-(-44)/22+((-4)*59) with calculation
Pavel [41]

Hi,

\frac{ ( - 7) - ( - 44)}{22 + (( - 4) \times 59)}

\frac{  - 7 - ( - 44)}{22 + (( - 4) \times 59}

\frac{ - 7 + 44}{22 + (( - 4) \times 59}

\frac{ - 7 + 44}{22 + ( - 236)}

\frac{37}{22 + ( - 236)}

\frac{37}{22 - 236}

\frac{37}{ - 214}

good look :)
