Question

do advertice of something, its an activity for you​

Answer 1

Answer:

Calculate the flow rate (Q) using,

Q = (Density)*(Flow area of tap) *(velocity of water)

Calculate the volume of the cylinder using,

V = (pi)*(r^2)*(h)

And finally calculate the time required using,

t = V/Q

(Logic: if Q litres of water is being poured into the container per second, how long will it take to fill V litres ?)

a tap with internal diameter 10 CM flows with the velocity of 10ms after travelling for 20 CM find it's diameter.

Explain the concept of electric potential difference in terms of the work done in transferring the charge.
