1st derivative gives velocity;
d r(t)/ dt = 2t i + 6 j + 4/t k
2nd derivative gives acceleration;
d^2 r(t)/ dt^2 = 2 i - 4/ t^2
Speed ;
Square root of (4 t^2 + 36 + 16/ t^2)
For a given time, like 2 seconds, t will be 2. And answer of speed will be scalar.

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
