Aparallel plate capacitor has two plates, both have an area of 1.7 m2 and the distance between the plates is 3.9 mm. the relative permittivity of the material between the plates is 9. what is the capacitance value, in units of nanofarads, for this parallel plate capacitor?

remember the permittivity of free space is equal to 8.85 x 10-12 c2n-1m-2 and the formula for a parallel plate capacitor is:

34.7 nF

Explanation:

The capacitance of a parallel-plate capacitor is given by:

where

is the permittivity of free space

is the relative permittivity of the material between the plates

is the area of the plates

is the distance between the plates

Substituting into the equation, we find:

dang that balls went far

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.
