Which best explains why metal cooking utensils often have plastic coating on their handles? plastic melts less easily and lasts longer than metal. plastic reduces the transfer of thermal energy to hands holding the utensils. plastic molds more easily into shapes like long, thin handles. plastic increases the rate of conduction from the utensil to the food.

Plastic reduces the transfer of thermal energy to hands holding the utensils. Hope this helped. (:

Hello there!

Metals are very good conductors of heat, this means that a metal cooking utensil can absorb a lot of heat fast, and be dangerous to the hands of person using it (because it also transmits this heat very fast), then there is needed some coating that prevents the heat transfer from the metal to the hand, and here is when the plastic coating in the handles comes to play. Then the right answer is:

" Plastic reduces the transfer of thermal energy to hands holding the utensils."

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.
