Answer:
The factors that affects the carrying capacity are the "food availability, water supply, environmental condition and living space"
Explanation:
The carrying capacity of an environment varies in different species and there are chances of being change over the time because of the various factors which is like food availability, water supply, environmental condition ad also the living space. The carrying capacity is mostly dependent upon the available resources and also the services available in the ecosystem. The symbol for the carrying capacity is K. If the population size will increase the carrying capacity are not sustainable and hence it will degrade the habitat.
To calculate the speed and velocity of the Ann`s we use the formula,
Here, d is distance and t is time and v if we take it with direction then it is called velocity and if we take it without the direction then it is called speed.
Given 
and 
.
Substituting these values in above equation we get
As Ann walked towards south direction therefore, Ann`s velocity is 3 mi/h south and her speed is 3 mi/h .
Answer:
Seismic waves are mechanical waves because they travel through the medium of the Earth.
Explanation:
Because it generates enough momentum to keep the train going with out really having to speed up
