Analyzing Lissajous Figures: Answer these questions about the last part assuming the function generators are always outputting sine waves.

Same Frequency, special cases: What do you expect to see if the two function generators are at exactly the same frequency and in-phase? What if they are out of phase (by 180 degrees)? What if they are 90 degrees out of phase?
Same Frequency, general case: In general, what do you expect to see if the two function generators are at exactly the same frequency with arbitrary phase?
Perfect n:m ratio: Suppose the two frequencies were exactly in an integer ratio (2:1, so one is twice the other; 3:2, so one is 3/2 of the other; etc.). What do you expect to see (as a static image) in this case? (Again, you may consider phase shift as well.)

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.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
