As chelsea removes her clothes from the dryer, she sees sparks, which are examples of a.) conduction b.) induction c.) static discharge d.) static electricity

C.) Static discharge

Explanation: Static discharge is the release of electron from an object charged by static electricity. static discharge is caused by an imbalance in the electric field within the charged particle,the spark seen when Chelsea removed her clothes from the dryer is an example of a static discharge.

The energy stored in  a particle and discharged by that particle is dependent on the particle size and capacitance of the particle.

the first, second, and fifth options

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
