2 they move in place, molecules only stop moving at absolute zero and away from each other in gases, they move around each other in liquids

The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. ... For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state.

A bicyclist travels 4.5 km west, then travels 6.7 km at an angle 27.0 degrees South of West. What is the magnitude of the bicycl
Dimas [21]

Answer:

<em>10.90km</em>

Explanation:

Magnitude of the total displacement is expressed using the equation

d = √dx²+dy²

dx is the horizontal component of the displacement

dy is the vertical component of the displacement

dy = -6.7sin27°

dy = -6.7(0.4539)

dy = -3.042

For the  horizontal component of the displacement

dx = -4.5 - 6.7cos27

dx = -4.5 -5.9697

dx = -10.4697

Get the magnitude of the bicyclist's total displacement

Recall that: d = √dx²+dy²

d = √(-3.042)²+(-10.4697)²

d = √9.2538+109.6146

d = √118.8684

<em>d = 10.90km</em>

<em>Hence the magnitude of the bicyclist's total displacement is 10.90km</em>

How do the nonliving parts of earth's systems provide the basic materials to support life?
MatroZZZ [7]
The abiotic community of the ecosystem or the nonliving objects in the earth's biosphere influences the survival, growth and development of the organism. They provide basic mmaterials to support life by the biogeochemical processes which is composed of many biological and environmental cycles which profoundly has factored the intiation and continuation of life on earth. They also provide the basic materials to support life by the undergoing process which is also initiated by the living creatures or the biotic society of the ecosystem.

The graph below shows the variation with distance r from the nucleus of the square of the wave function, Ψ^2, of a hydrogen atom
Ludmilka [50]

The region a represents the distance of the electron from the nucleus.

According to the wave mechanical model of the atom, the probability of finding an electron within a given volume element (representing the atom) is the square of the wave function psi.

Since a is the region in space where there is the greatest probability of finding the electron in the atom, it follows that distance of the electron form the atom is always a.
