Assume a nerve of 0.50 m in length is stimulated and sends electrical impulses to the brain. along this section of nerve the velocity of the signal is around 0.40 m/s. how long does a signal take to travel the length of the nerve? assuming the charge traveling through the nerve to be that of 100.0 electrons, what would be the current traveling through the nerve? what would be the magnetic field strength 0.01x10 m away from the nerve? what would the maximum force generated by the current through the nerve be at that same distance?

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

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.
