the total charge of 9.0 mC passes through a cross-sectional area of a nichrome wire in 3.5 sa What is the current in the wire? b. How many electrons pass through the cross-sectional area in 10.0 s? c. If the number of charges that pass through the cross-sectional area during the given time interval doubles, what is the resulting current?

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

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.
