Answer:
option 4
Explanation:
Light's velocity in air ( 3 × 10^8 m/s ) is much greater than sound's velocity in air ( 343 m/s )
Hence due to difference in velocities , during lightning light is seen first & sound is heard later
The way in which objects exert forces on each other is described by Newton’s 3rd law of motion

Explanation:
The equation that relates the conductance G with the conductivity
is given by
where A is the cross-sectional area while L is the length of the conduit.
In our problem, the area is
and the length is
, while the conductance G is
, therefore re-arranging the equation we can find the conductivity:
