Oscilloscope time base problem. you are asked to display a 1 khzsine wave signal on the screen. since the period t is related tothe frequency f by the formula t = 1 / f, the period of this waveis 1/(103/s)=1ms, so a reasonable setting for the"time/div" dial is 1 ms/div. but suppose you select aninappropriate setting for the time/div dial by mistake. what wouldyou see if you set the dial on 1 μ s/div? 100 ms/div? a. asine wave shifted to the left on 1 μ s/div and to the right on100 ms/divb. a(nearly) horizontal line on 1 μ s/div andmany (nearly) vertical lines of 100 ms/divc. nothing on either (no trigger)d. anormal sine wave in both casese. none of these

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

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.

connectedness in handwriting analysis is a useful tool in establishing the writer’s method of thinking and its perception in where he/she fits in to the environment around him in the social sense. in addition, the more connected the writing of an individual, the more he/she is flexible and single minded.
