Answer:
C. Decreasing the distance between the objects.
Explanation:
Gravitational force depends on mass and distance. The farther the objects are apart, the less gravitational force/pull they have.
Answer:
Angular velocity, 
Explanation:
The mass of the skater, M = 74.0 kg
Mass of each arm, 
( since it is 13% of the whole body and each arm is considered)
Mass of the trunk, 
Total moment of Inertia = (Moment of inertia of the arms) + (Moment of inertia of the trunks)
The final moment of inertia of the person:
According to the principle of conservation of angular momentum:
Answer:
For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Explanation:
Every force sent into an object will sent a force in return.
If you smack a table, you can feel the table "push back"
The sparse area surrounding a spiral galaxy is called its halo. Hoped this helped!
Answer:
b) Distance covered before stopping.
Explanation:
If you want to find the distance d required to come to a stop starting at some initial speed v, with braking acceleration a, use the kinematic relation
vf2 - vi2 = 2ad
vi = initial speed at the moment braking begins = v
vf = final speed = 0 (comes to a full stop)
-v2 = 2ad
d = -v2/(2a)
