The resistance of a liquid to flowing is its? a. pressure. b. temperature. c. viscosity. d. volume.

the correct answer is viscosity

c. viscosity.

Explanation:

Pressure of the gas is defined as the force exerted by the particles on the walls of the container.

Temperature of the gas is defined as the degree of hotness or coldness of a body.

Volume of the gas is defined as the space occupied by a substance.

Viscosity is defined as the resistance to the flow of a fluid. More are the inter molecular forces between the particles of a liquid, the more the viscosity of the liquid and thus it will flow slowly.

Example: Oil is more viscous than water and thus has higher resistance to flow than water.

answer: b.

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.
