Water enters a shower head through a pipe of radius 0.0112 m at 3.25 m/s. what is its volume flow rate?(unit=m^3/s) PLEASE HEL M

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
