Answer: A. carrying capacity
A carrying capacity of the ecosystem or the environment refers to the maximum number of individuals in a population of species that an ecosystem can support in terms of available resources like food, habitat, water and other necessities. If the size of the population exceeds the environmental carrying capacity, this will result in death as all individuals will not be able to derive resources and the population size will return to previous levels.
Answer:
12.5 ft/s
Explanation:
Height of person = 6 ft
height of lamp post = 10 ft
According to the question,
dx / dt = 5 ft/s
Let the rate of tip of the shadow moves away is dy/dt.
According to the diagram
10 / y = 6 / (y - x)
10 y - 10 x = 6 y
y = 2.5 x
Differentiate both sides with respect to t.
dy / dt = 2.5 dx / dt
dy / dt = 2.5 (5) = 12.5 ft /s
Answer:
minimum length of a surface crack is 18.3 mm
Explanation:
Given data
plane strain fracture toughness K = 82.4 MPa m1/2
stress σ = 345 MPa
Y = 1
to find out
the minimum length of a surface crack
solution
we will calculate length by this formula
length = 1/π ( K / σ Y)²
put all value
length = 1/π ( K / σ Y)²
length = 1/π ( 82.4 
/ 345× 1)²
length = 18.3 mm
minimum length of a surface crack is 18.3 mm
Speed = distance/time
Time = 90/60 = 1.5 hours
Speed = 54/1.5
Speed = 36km/h
<u>Softly, surrounded by a fringe of inquisitive bright creatures</u>, itself a silver shape beneath the steadfast constellations, Simon's dead body moved out toward the open sea.
This excerpt is from 'Lord of the Flies', by William Golding. It is inspired by the following concepts:
- adolescent cruelty tendencies
- his tenure as a teacher at a school for males only
- his military service
- the Coral Island
According to Golding, the subject of the book is that the community is imperfect because humankind is flawed. Considering this, we know that the "flies" in the novel stand for death.
