The main source of carbon dioxide in an ecosystem is the carbon dioxide gas present in the atmosphere. This carbon dioxide is used by the  plants and animals in different ways.

The plants use this carbon dioxide to perform the process of photosynthesis.This is carried out by the help of green pigment called chlorophyll that absorbs light from the sun, water from soil and carbon dioxide from atmosphere.

The carbon in animals comes when they eat these plants.

Approximately how far, in cm, does the blood move during one beat? Express your answer to two significant figures and include th
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
