Two balloons with charges of 6.08 mircoCoulomb and 8.2- microCoulomb attract each other with a force of 0.0648 Newton. Determine the separation distance between the two balloons.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

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.
