Answer:
2C charge will flow from ground and cloud
Explanation:
We have given rate rate of flow of charge 
Time is given as 
WE have to find the how much charge flows between the ground and cloud in this time
So the charge flow is given by 
So 2C charge will flow from ground and cloud
Answer:
Explanation:
This is a case of interference of sound , akin to YDSE in optics .
Here, like interference dark and bright fringes, region of silence and intense sound will be formed due to destructive and constructive interference respectively.
Here d = distance between two sources = 5 m
D = distance of source and screen = 12m
position of first destructive interference
= λ D /2d
1 = λ 12 /2x 5
λ = 5 / 6 m
frequency = v / λ
= 343 x 6/ 5
= 411.6 Hz
