How can speed be described?
Select one:

The mass multiplied by the acceleration of an object.

The force on an object divided by the mass of an object.

The distance an object travels at a certain velocity.

The distance travelled by an object in a certain time.

Answers

Answer 1

The correct answer is:  [D]:

___________
→  " The distance traveled by an object in a certain time."

___________

Explanation:

Choice:  [A]:  "the mass multiplied by the acceleration of an object."
 refers to:  "force".    " F = m*a " .   → Rule out:  Choice: [A].
___________

Choice:  [B]: "the force on an object divided by the mass of an object."
 refers to:  "acceleration".  " F /m = a ". → Rule out:  Choice: [B].
___________
Choice:  [C]:  "the distance an object travels at a certain velocity."
 refers to: " the time period traveled at a specific speed AND direction."
___________

Choice:  [D]: " the distance traveled by an object in a certain time"."

refers to:  "speed".  which is our answer!

___________

Note:  " speed = distance / time ";  That is:  " s = d/t " ;

Note that for "speed" ; the "direction of travel is irrelevant."

 → So; we can rule out: "Choice:  [C]."

___________

The correct answer is:  Answer choice:  [D]:

  →  " the distance traveled by an object in a certain time."
___________

Oxygenated blood leaves the lungs and enters which heart chamber?

Answers

left atrium

Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

What happens when you heat a sugar and water mixture?

Answers

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

Answer:

[tex]beinggreat78~here~to~help![/tex]

When you heat a sugar-water mixture, the sugar rapidly dissolves, because the electrons in the heat molecules intensify and work to dissolve the sugar molecules into a solution. The scientific formula the heat molecules break is known as [tex]C_{12} H_{22}O_{11}[/tex], which is also referred to as sugar.

C. the model shows how salinity of water affects its density

D. the model shows how the density of water differs between the north Atlantic and other parts of the ocean.

Answers

Answer:

d

Explanation:

The ocean conveyor belt shows the movement of the oceanic water and the salinity. The model represents the density of the water in different regions of the world. Thus, option d is correct.

What are ocean conveyor belts?

Ocean conveyor belts are the oceanic current movement in their oceans across others and how the water moves across the water bodies across the globe.

The model shows that high salinity water gets heavy and sinks in the ocean of North Atlantic but the water of the Indian and the pacific oceans are less saline and remains at the surface.

Therefore, option D. the water differs in oceans based on density.
