Which unit is part of the si system?

gram

pint

quart

gallon

Explanation:

The SI system refers to the International System of Units and it's the most used around the globe. The use of this system is due to the necessity of using the same units in researches from different countries.

This system was first call the MKS system (Meter-Kilogram-Second). The SI system uses these fundamental magnitud units too, meter for length, kilogram for mass and second for time.

Therefore, the right answer here is gram, because it's the base of kilogram which is used in the SI system.

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.

the answer to this is proletariats.

hope this : )
