Why were wolf populations removed from Yellowstone national park
Oduvanchick [21]

In the 1800s, westward expansion brought settlers and their livestock into direct contact with native predator and prey species. Much of the wolves’ prey base was destroyed as agriculture flourished. With the prey base removed, wolves began to prey on domestic stock, which resulted in humans eliminating wolves from most of their historical range. Predator control, including poisoning, was practiced here in the late 1800s and early 1900s. Other predators such as bears, cougars, and coyotes were also killed to protect livestock and “more desirable” wildlife species, such as deer and elk.

19. A satellite goes along an elliptical path around earth. The rate of change of area swept by the line joining earth and the s
grigory [225]

Answer:

r^\frac{1}{2}

Explanation:

Angular momentum, L = m v r

areal velocity = \frac{dA}{dt}

according to kepler's 2nd law

\frac{dA}{dt}=\frac{L}{2m}

since, we know that

v=\sqrt{\frac{Gm}{r} }

areal velocity= \frac{mvr}{2m} = \frac{vr}{2}

now substituting value of v in areal velocity we get

\frac{1}{2}\sqrt{GMr}

hence from above equation of rate of change of area swept i.e. areal velocity is proportional to   r^\frac{1}{2}
