Part a
power = 3.9 \times {10}^{33} erg \: {sec}^{ - 1}
energy \: in \: 3.25 \times {10}^{3} sec = 3.9 \times {10}^{33} \times 3.25 \times {10}^{3} = 12.675 \times {10}^{36}
part b
1.435 . 10^3 mm = 1.4m
1.435 . 10^-3 mm = 0.001435m
so the first one ie 1.4m is more reasonable as tge second one is too small quantity.
Hope it helps.
Answer:

Answer:
Han= 24 minutes
His sister= 24 minutes
His Dad= 36 minutes
Grandmother= 42 minutes
Step-by-step explanation:
Please see attached picture for full solution.
Where the working split, see the right hand side.
The question states that Han's Dad sits 1.5 times as long as both Han and his sister. There could be 2 interpretations for this:
- Dad sits for 1.5 times of (Han and his sister)
- Dad sits for 1.5 times of Han and 1.5 times of Han's sister
I've done the working for both scenarios and found out that the 1st case cannot be true since Dad would've sat for 50.4 minutes when the bus ride is only 42 minutes! Moreover, there wouldn't be enough information to know how long Han and his sister sat for.
The second case is possible and it's working is on the right.
Feel free to ask if you have any enquiries :)
Answer:
Sophia now has 39 cents.
Step-by-step explanation:
One quarter = 25 cents
Since Sophia had 64 cents until she spent 25 cents (1 quarter).
So we subtract 25 cents from 64 cents.

Therefore, Sophia now has 39 cents.
