How might an ecologist Measure population density of pine trees in an actual forest?

1 answer:

4 0

<span>Ans : The best way to estimate the population density of pine trees in an actual forest is to count the number of trees in a small area and than multiply to find the number in a large area. To get the most accurate estimate, your sample area should be typical of the larger area. Suppose you count 10 pine tree in 100 sq meters of the forest. If the entire forest were 100 times the size, you would multiply your count by 100 to estimate the total population density, or 1000 (10X100) pine trees.</span>

Answer:

a) d = 6.0 m

Explanation:

Since car is accelerating at uniform rate then here we can say that the distance moved by the car with uniform acceleration is given as

$d = \frac{(v_f + v_i)}{2} \times t$

here we know that

$v_f = 10 m/s$

$v_i = 0$

$t = 1.2 s$

now we will have

$d = \frac{(10 + 0)}{2}\times 1.2$

$d = 5 \times 1.2$

$d = 6.0 m$

inessss [21]

If the vertical component is 29.6 m/s down, and the horizontal component
is 54.8 m/s parallel to the surface, then the magnitude of the slanty vector is

√(29.6² + 54.8²) = √(876.16 + 3003.04) = √3879.2 = 62.28 m/s .

That's 139 mph ! Wow !
