Assume we have a 1D print pattern with a resolution (i. e., spatial sampling frequency) of 120 dots per cm, which equals approximately 300 dots per inch (dpi) and a total signal length of N= 2800 samples. Calculate the i. Sampling interval [2]
ii. Physical signal length [1]
iii. The fundamental frequency of this signal (again implicitly assumed to be periodic) [1]
iv. Maximum frequency that can be represented by this signal without aliasing [2]
v. A 1D optical scanner for sampling film transparencies is supposed to resolve image structures with a precision of 3,000dpi. What spatial distance (in mm) between samples is required such that no aliasing occurs?

small = small current large mag large current

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.
