Pls help!! Why do scientists use models?

Question 1 options:

because some systems are so large, small, or complex they are difficult to predict

all answers are true

to aid in the development of questions and explanations about systems

to replicate and simplify physical reality to allow for precise experiments

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
