Answer:
Because there is nothing out in space , the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears.
It is a mechanical wave and cannot travel through a vacuum.
We know, I = Q / t
Here, Q = 150 C
t = 30 s
Substitute their values,
I = 150 / 30
I = 5 A
In short, Your Answer would be 5 Ampere
Hope this helps!
