Source of error during electrolysis of iron nail

In this simple experiment we assemble a home device for electrolysis and break down water! ... An error occurred while retrieving sharing information. ... the beaker, which are connected to a source of direct current, for example a battery. ... chromium, zinc and others – the metal and hydrogen will be deposited on the anode.

i'm on my way to history not a mistory.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
