In this project, you will choose a system in which energy changes occur. Then you will develop and use two models, based on evidence, that illustrate the energy in that system. One of your models must be a potential-energy diagram. At least one of your models must show that a system's total energy is a combination of the energy associated with the motions of its particles and the energy associated with those particles' relative positions. Your models should also show any transformations of energy taking place in your system — for example, the transformation of potential energy to kinetic energy or of kinetic energy to thermal energy. In addition, your models should describe any flow of energy into or out of the system.

i guess it’s a and b

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

search it up!

explanation:

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.
