Marysya12 [62]

Answer:

7.5cm

Explanation:

Velocity vs Time Graph:

When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.

Velocity vs time graph:

Is shown in the attached image

A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.

Height of the triangle is the velocity (v) = 0.75m/s

The base of the triangle is the time interval (t) = 0.2sec

Distance travelled = Area of triangle

Distance travelled

= 1/2(V) * t

= 1/2(0.75m/s) * 0.2s

= 0.0075m

=7.5cm

Thus, during one beat blood flows  7.5 cm

What is a non-example of diffusion?
prisoha [69]
<span>A non-example of diffusion is a brick.
Diffusion is termed as movement of molecules from a region of high concentration to a region of low concentration. A good example is how oxygen enters the body during external respiration which is referred to as breathing.
 Some of examples of diffusion are diffusion of mineral salt in the soil water into the root hairs cells. Diffusion of oxygen into the carbon dioxide and cell out of the cell in a unicellular like an amoeba, Diffusion of oxygen through the lungs and carbon dioxide out to the lungs of mammals.
 Diffusion of carbon dioxide and oxygen out by the leaf through the stomata.</span>

Passive transport can be explained by which
Sedaia [141]

Answer:

It must be large particles move into cells, unless there is another option

Explanation:

Passive transport does not require energy, so the first one is incorrect

Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect

So it should be large particles can move into cells, unless of course there is another option
