g Design a simple op-amp oscillator-based function generator. Your generator must produce three different waveforms: Sinusoidal, square, and triangular waves. You may use switches to select the waveform sent to the output. The oscillator frequency should be 500 Hz, and produce a peak voltage of no less than 0.5 V. You may use batteries, or our DC power supplies to power your function generator. Standard devices may be obtained from the EE shop; if you need other devices you will have to purchase them.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

c)as speed changes, wavelength and frequency change.

everything changes!

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.
