Answer:
The primary purpose in creating national parks is to protect the land from development and pollution.
Explanation:
National parks are owned by the national government. This areas are strictly reserved for habitat of wild animals.
The main purpose for creating national parks is to reserve some space for nature. This area is protected from pollution and development.
Thus, answer for given question is protect the land from development and pollution.
C
Because magnet involves 2 opposite poles so therefore it would have to be C
Answer:
B) below the plane and behind it.
Answer:
Explanation:
Let the initial rotational inertia be I and final rotational inertia be I / 6 .
Let the initial angular velocity be ω₁ and final angular velocity be ω₂.
Applying conservation of angular momentum law
I x ω₁ = I / 6 x ω₂
6 ω₁ = ω₂
initial rotational kinetic energy = 1/2 I x ω₁ ²
Final rotational kinetic energy = 1/2 ( I / 6 ) x ω₂ ²
Final rotational kinetic energy / initial rotational kinetic energy
= ( 1 / 6 ) x ω₂ ² / ω₁ ²
= ω₂ ² / 6ω₁ ²
= 36 ω₁ ² / 6ω₁ ²
= 6 .
