The operation of hydraulic brakes in a car is based upon. principle. fill in the blank

It is based upon the principle of Pascal's law

Explanation:

As we know by the Pascal's law that when we apply pressure at any point of the fluid then that applied pressure is transferred to all points of fluid equally without any change in all direction.

In hydraulic brake system it will be same that occurs in the system. When we push the brake pedal then the pressure is exerted into the brake oil inside it

This pressure is transmitted by the fluid in all directions without any change or without any loss.

Now this pressure is exerted at larger area then due to this it will exert large force as we know that

Force = (Pressure)(Area)

So The operation of hydraulic brakes in a car is based upon the Principle of Pascal's law.

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.
