Answer:
The correct answer is C , because it increases and decreases
Explanation:
When you lay down your weight is distributed over a much larger surface area than while standing. You are putting a much greater force on a much smaller area standing.
Answer:
all objects in the universe.
The Correct Answer is <u>D.Infrared/</u> <em>INFARED has a lower frequency than visible light/</em>
The new rotational speed of the combined system is 32 rad/s
<u>Explanation:</u>
Given-
Moment of Inertia, I = 8 kg m²
speed of rotation, ω = 4 rad/s
Mass of the lump = 1 kg
distance = 1 m
New rotational speed = ?
We know,
When the lump is dropped on the rotating disc then the angular momentum remains conserved.
Angular Momentum of the disc, Lₐ = Iω
Angular momentum of the lump, L ₓ = mvR
Since the angular momentum remains conserved,
Lₐ = Lₓ
8 X 4 = 1 X v X 1
New rotational speed, v = 32 rad/s
Therefore, the new rotational speed of the combined system is 32 rad/s.
