Acceleration  of a body is defined as rate of chance in velocity with respect to time and its S.I. Units are meter/sec^{2}/ or m/s^{2}

Magnitude of average acceleration of a body = (final speed - initial speed)/time interval = (v- u)/t

where, final speed =v= 11 m/s; initial speed = u = 6 m/s; and time interval = t = 3 s

Hence acceleration = (11-6)/3 = 5/3 = 1.67 m/s^{2}

<h2>Answer:</h2>

The acceleration of the object is 1.667 m/s2.

<h3>Explanation:</h3>

Given data:

Initial velocity = v1 = 6 m/s

Final velocity = v2 = 11 m/s

Time period = t = 3 s

Solution:

Acceleration = a = ( v2 - v1)/t

By putting values in the above formula:

Acceleration = a = (11 - 6)/3

                        a = 5/3 = 1.6667

Explanation:

Acceleration of an moving object is the change of velocity of an object divided by the total time taken by the object which is time period. So by putting values it comes that acceleration of object is 1.6667 m/s2.

The unit is meter per second square.

The population change equation is Population Change = (Natality - Mortality) + (Immigration - Emigration). Which equation would
Snezhnost [94]

Answer:

B. natality + immigration = mortality + emigration

Explanation:

Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.

Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.

Some of the factors that influence migration selectivity are income level, age, education, gender etc.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Therefore, the equation which would create a stable population is given by the formula;

Natality + immigration = mortality + emigration.

How do animals and humans cause erosion ?​
erastova [34]

Animals cause erosion in other ways too. When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is much more likely to be eroded by wind and water. Animals cause weathering and erosion on rocky shorelines.

During respiration, members of the animal kingdom use ______ and then release ______ as a waste gas
raketka [301]

During respiration, members of the animal kingdom use oxygen and then release carbon dioxide as a waste gas.

Members of the animal kingdom have a respiratory system that is composed of muscles, and airways that functions together to transport air into lungs, and the oxygen is used by cells. Carbon dioxide is also transported away from the cells as a waste gas. Respiration relies on other systems, such as the circulatory system, to transport oxygen and carbon dioxide to and from cells.

Why is mechanical digestion and important to chemical digestion
dangina [55]
They are both important because mechanical has to do with physical - cause mechanical means physical, so chewing your mouth is physical (you break your food into smaller pieces physically). And then chemical digestion is when food and saliva mix together. They happen when breaking down food into nutrients - enzymes. Enzymes are important for that process, because they make a nutrient.



Hope this helps!!
