Answer:

In CONVECTION, heat energy is carried by the movement of particles of matter. In CONDUCTION, heat is transferred by particles vibrating. In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one.

What is the difference between point source and nonpoint source water pollution

Komok [63]

Point source means: the pollution that comes from a single point (examples)

Sewage pipes releasing sewage into a ditch

Smokestack style factory chimneys

Oil pipes

Pollution which is caused by rain fall or snow melting into the ground. As the runoff moves, it picks up and carries away natural and human made pollutants, Finally reaching a lake, river, ocean, groundwater.

After abdominal surgery a client returns to the unit with a nasogastric (ng) tube to low intermittent wall suction. the primary

Semmy [17]

The correct answer is: check for correct placement of the NG tube.

An adequately functioning nasogastric (NG) tube shouldprevent nausea and vomiting because stomach contents

are continuously being removed. Using the NG after abdominal surgery is a routine postoperative procedure until gastrointestinal tract start tofunction properly. The patency of the tube should be checked together with the amount and character of gastric drainage.

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (

Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

$|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}$

$|a| = \sqrt{9+16+49}$

$|a| = \sqrt{74}$

$|a| =8.6 \ mg/mL$

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

$|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}$

$|b| = \sqrt{9+16+49}$

$|b| = \sqrt{74}$

$|b| =8.6 \ mg/mL$

Hence, for both Lake A and B, the magnitude of change is the same.

Good afternoon everyone Umm What is refraction of light hope it's easy good day ✌️

jeyben [28]

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

Here you go, and i hope you have a good day too :)
